Comparison: Quick Verdict
DJI Mic 2 is my pick for a small creator kit, especially two-person interviews and work split between a phone and camera. The Sennheiser ew 112P G4 camera lavalier kit makes more sense when you want a wired lavalier feeding an established UHF bodypack workflow and can manage its regional frequency band. DJI adds internal backup recording and a compact two-transmitter receiver option; the G4 kit has replaceable AA power but no internal recorder. Neither brand name guarantees better dialogue in every location.
This DJI Mic 2 vs Sennheiser comparison concerns the ew 112P G4 camera kit: SK 100 G4 transmitter, EK 100 G4 receiver and an ME 2 omnidirectional lavalier. Sennheiser also sells EW-DP and Profile Wireless systems with different features. Their specifications do not describe this G4 kit. On the DJI side, I compare the Mic 2 two-transmitter, one-receiver and charging-case package; a transmitter-only listing is a different purchase.
Having used both styles of system in videography, I favour DJI’s quick handling for small creator projects. The touchscreen receiver and small clips are convenient when I am also managing the camera. With a bodypack-and-lavalier setup, I give more attention to cable placement and receiver settings. Those are workflow preferences, rather than a new laboratory sound or range test.
The important decision is what reaches your recorder, how many people need microphones and what happens if the wireless feed fails. Below I compare design, recording, power, compatibility, setup and real shooting jobs, then explain what to check in a current or used offer.
Key Takeaways
Choose a complete signal path. DJI can send two transmitters to its receiver, while the specified G4 camera kit serves one transmitter and receiver. Two speakers require a different G4 system budget and enough recording inputs.
Separate three different clocks. DJI’s six-hour operating specification, approximately 18-hour total with case recharging, and 14-hour 24-bit storage capacity are different claims. None means one uninterrupted 18-hour take.
Check the actual mode. DJI’s 32-bit float files are recorded inside the transmitter. Bluetooth-to-phone operation has restrictions; it does not preserve every receiver-based feature. G4 sends analogue audio to your camera or recorder and has no built-in file backup.
Quick Comparison Table of DJI Mic vs Sennheiser
| Buying question | DJI Mic 2, 2 TX + 1 RX + case | Sennheiser ew 112P G4 camera lavalier kit |
|---|---|---|
| How many speakers? | Two transmitters into one receiver; check output channel mode | One SK 100 G4 transmitter and one EK 100 G4 receiver |
| Wireless system | 2.4 GHz receiver link; separate Bluetooth mode | Analogue UHF, regional frequency-band variants |
| Backup files | 8 GB inside each transmitter; 24-bit or 32-bit float WAV | No internal recorder in the specified transmitter/receiver |
| Power per session | Up to six hours under DJI’s stated test conditions | Typically eight hours from two AA batteries in each unit |
| Long-day power | Case supplies approximately two additional charge cycles; around 18 hours total | Carry suitable spare batteries or compatible rechargeable packs |
| Camera connection | Receiver 3.5 mm camera output; verify cable and camera input | Receiver 3.5 mm analogue output; supplied camera/XLR cables depend on package |
| Phone/computer route | Compatible receiver adapter/USB connection; Bluetooth app limitations | Requires a suitable analogue input interface and cabling |
| Published range | Up to 250 m FCC or 160 m CE, unobstructed and interference-free | Up to 100 m manufacturer’s range claim; location still matters |
| Controls | 1.1-inch touchscreen and dial on receiver | Physical buttons, backlit display and frequency setup |
| Before buying | Check exact kit, adapters, batteries and recording workflow | Check exact G4 components, legal regional band, lavalier and cables |
The table is useful for eliminating unsuitable packages, not declaring a winner from one large number. A 250-metre advertised range does not prove that DJI will outperform G4 in your venue. A different RF band, antenna position, crowded Wi-Fi environment, body obstruction or camera cable can change the outcome. Test the actual working positions before an important recording.
Likewise, digital file depth is not a G4 radio specification. G4’s analogue output becomes a digital file in the connected recorder. The recorder’s settings, microphone positioning and gain path all affect that file. Do not compare DJI’s internal 32-bit float setting with an invented G4 24-bit recorder.
Overview of DJI Mic 2 vs Sennheiser
DJI Mic 2
DJI Mic 2 combines small clip-on transmitters, built-in microphones, optional external lavalier input and a compact receiver. The two-transmitter kit suits an interviewer and guest without mounting two separate receivers. A charging case stores and recharges the main components, which reduces loose-item handling between short shoots.
Its distinctive advantage is the option to record a separate file inside each transmitter. That can give an editor another source when the camera feed has a problem, provided internal recording was enabled and the transmitter remained powered. You still need to export, identify, synchronise and listen to those files. Backup recording is a workflow to manage, not a promise that every bad take is recoverable.
Sennheiser ew 112P G4
The G4 kit is a different arrangement: an ME 2 lavalier connects to the SK 100 G4 bodypack, which transmits to the EK 100 G4 camera receiver. The receiver feeds analogue audio into a camera or recorder. This keeps the microphone itself small on clothing and leaves the transmitter elsewhere on the subject, but introduces a lavalier cable to dress and secure.
G4 makes sense for someone already comfortable with UHF frequency selection, bodypacks and recorder gain. The exact regional band matters, particularly for imported or used equipment. A lower-priced unit is no bargain if its frequency range is unsuitable or not permitted for your location. Check the unit’s label and local requirements before paying.
Core Features Comparison
My choice starts with the recording job. A solo creator moving between phone and mirrorless camera has different needs from an operator adding one lavalier to an established camera rig. DJI simplifies a compact two-person setup; G4 provides a familiar single-channel camera-lavalier path with replaceable power. Neither requires a blanket claim that creators get inferior audio or professionals must choose Sennheiser.
Design and Build Quality
Physical Layout and Aesthetics
DJI puts the microphone and transmitter together in a small visible clip-on unit. That is convenient when appearance is acceptable and there is little time to fit a concealed lavalier. Its receiver provides an at-a-glance screen for the two transmitters. Plan the receiver mounting position so you can still see the camera display and reach the controls.
G4 separates the capsule and bodypack. The small lavalier can be placed near the speaker’s mouth while the larger pack sits on a belt or in a suitable pocket. The receiver needs space on the camera rig and a clear cable run. Sennheiser specifies approximately 160 g including batteries for each G4 bodypack unit, compared with DJI’s 28 g transmitter specification; those figures describe different assemblies, not complete-kit carry weights.
Material and Durability
The G4 transmitter and receiver use metal housings. Do not assume that an older-looking bodypack is a lightweight plastic alternative or that the DJI kit automatically wins durability. Inspect battery doors, antenna condition, clips, connectors and charging contacts on the actual equipment. A solid housing cannot prevent damage to an exposed lavalier lead.
For used equipment, ask for clear photographs of the labels and powered displays as well as the front panel. Corroded battery contacts, a loose locking connector or intermittent cable can matter more than cosmetic scuffs. For DJI, check that both transmitters charge and that the receiver, case and required phone adapters are present. A listing photograph should show the model you are buying.
Clip Mechanism and Portability
I find DJI’s small clip-on layout useful for quick changes between subjects. A magnet is convenient, but it still needs a secure clothing position. DJI cautions about heavy clothing, vigorous movement and proximity to items such as pacemakers and bank cards. A magnet does not make every fabric or activity suitable.
With the G4 lavalier, leave sensible cable slack and prevent clothing from rubbing the capsule. Put the bodypack somewhere the subject can move comfortably without pulling the cable. For either system, a short movement check with headphones is more useful than judging how tidy the setup looks while everyone is standing still.
Technical Specifications
Audio Quality and Recording Capabilities
DJI specifies 8 GB of storage in each Mic 2 transmitter: up to 14 hours of 24-bit audio or about 11 hours of 32-bit float audio. These are storage capacities, not battery endurance. The files are WAV, and the transmitter does not accept an external memory card. Export recordings over USB to a computer before clearing them.
32-bit float gives an editor useful level-adjustment latitude in the internal recording, but it does not move a badly placed microphone closer to the speaker or remove clothing rustle. It also does not convert the camera’s analogue input into a 32-bit float recording path. Listen to the delivered camera recording and the backup separately rather than assuming they are identical.
G4 has no comparable internal recorder. Its analogue wireless link uses Sennheiser’s HDX companding system. The supplied lavalier, transmitter sensitivity, receiver output and camera input need to work as a chain. A wider published frequency response alone does not establish warmer speech or a superior listening result; mic and line-input specifications also describe different scopes.
Connectivity Options
DJI’s receiver-based 2.4 GHz link is distinct from connecting a transmitter directly to a phone over Bluetooth. DJI says internal recording and intelligent noise cancelling are unavailable when its transmitter is connected to a smartphone by Bluetooth. App and operating-system compatibility matter, so verify the exact recording app rather than assuming the phone’s native camera will use it.
The specified G4 kit is an analogue UHF system. It does not become a Bluetooth microphone or a USB digital interface because other Sennheiser products have those capabilities. A phone or computer needs a suitable interface for the receiver’s analogue output. Include that interface, cable and monitoring route in the budget.
Battery Performance and Charging Features
DJI lists six hours for both transmitter and receiver under a stated camera-connected test with internal backup recording off. The case can recharge two transmitters and one receiver approximately twice, giving the advertised roughly 18-hour total across charges. Recharging takes time, so schedule breaks and test the required mode for a long interview.
Sennheiser specifies typical eight-hour operation using two AA batteries or its compatible BA 2015 rechargeable pack in each G4 unit. Replacing batteries interrupts that unit’s operation; it is not hot-swapping without a break. Carry a consistent set of suitable spares and track which ones are fresh. Compare complete-day power plans rather than calling either product an uninterrupted all-day system.
Compatibility with Devices
Smartphone and Computer Connectivity
DJI is the easier starting point when the same kit must move between a camera, phone and computer. Check whether the actual bundle includes the required USB-C or Lightning receiver adapter, whether the phone case obstructs the connector and whether the selected app accepts the microphone. A transmitter-only bargain does not include the full receiver workflow.
The marketing illustration above groups several Mic 2 features. Its 14-hour figure refers to 24-bit storage capacity; 32-bit float storage is approximately 11 hours, and the 18-hour figure includes case recharging. Those numbers should not be read as simultaneous battery promises.
For a computer session, select the intended input in the recording software, check left/right channel routing and make a short recording before the call or livestream. For direct Bluetooth phone use, check DJI’s mode restrictions before relying on internal backups. A successful pairing icon is not proof that your recording app captured the external microphone.
G4 can feed a suitable computer or phone interface, but the interface must accept the receiver’s output correctly. A passive plug-shape adapter is not automatically an analogue-to-digital audio interface. Confirm the connection path and monitoring on the actual equipment instead of ordering several inexpensive adapters on the assumption that they are interchangeable.
Integration with Cameras and Handheld DJI Products
Both systems can feed cameras with appropriate microphone inputs and cables. Set the receiver output and camera input so normal speech has useful headroom, then listen to a recorded clip. A cold-shoe mount secures hardware; it does not itself guarantee an audio connection. A camera lacking a suitable input needs a different recording path.
DJI also supports direct Mic 2 transmitter connections with compatible products such as Osmo Pocket 3 and Osmo Action 4. These are handheld/action-camera workflows, not proof of microphone integration with a flying drone. Check the exact device, firmware and supported mode before buying a transmitter without a receiver.
Functionalities and Ease of Use
Interface and Control Elements
I like the Mic 2 receiver’s touchscreen and dial for quick changes while handling a small camera setup. Before a take, make sure the correct transmitter is selected and that both speakers are reaching the intended channels. Locking down a reliable setup is more useful than changing processing repeatedly while the subject is speaking.
G4 uses buttons and a backlit display for frequency, RF/audio indication and settings. Its transmitter sensitivity and receiver output adjustment serve different purposes. Do not copy a gain number from DJI into the G4 menus: the ranges and points in the signal path differ. Learn the menus with headphones and an ordinary speaking voice before an important job.
Setup and Operational Flexibility
A DJI receiver can handle two transmitters, but recording mode decides what reaches the camera. Stereo separates the transmitters into channels; mono combines them; mono safety-track mode provides a lower-level track. Check the manual for the selected output and split the channels appropriately in editing. A second channel is only useful if the recorder and editing workflow preserve it.
G4’s single camera kit does not capture two independent transmitters at once. Adding a second speaker normally means another suitable channel and receiver plus enough inputs or a mixer. Its bank/channel choices and infrared synchronisation help configure the radio link, but frequency planning still matters when several systems operate together.
Additional Accessories and Customisations
Price the complete job: lavaliers if you prefer concealed microphones, suitable wind protection, mounting, cables, adapters and spare power. DJI’s kit configurations vary. Sennheiser’s ew 112P G4 and ew 122P G4 packages differ in the included lavalier, so an ME 4 cardioid listing should not be treated as the same ME 2 omnidirectional package.
The DJI charging case is for storing, linking and recharging the microphone components. Do not buy it expecting a general-purpose phone power bank. For either system, check the manufacturer’s supported maintenance instructions and exact model before installing firmware or replacing parts; instructions for EW-DP or Profile Wireless are not G4 instructions.
Decision Matrix: Build the Recording Path First
| Your recording job | Start here | Check before the first important take |
|---|---|---|
| Two speakers, one small camera rig | Mic 2 two-transmitter receiver kit | Separate channels, both voices, camera input and internal files |
| One lavalier into an existing UHF camera workflow | ew 112P G4 with the correct regional band | Frequency permission, scan/sync, output level and spare AA sets |
| Phone-only recording with a backup requirement | Mic 2 receiver and a compatible phone adapter | App captures receiver input; selected backup mode works |
| Bluetooth transmitter directly to a phone | Mic 2 only if the app/mode meets the job | Internal recording and noise cancelling restrictions |
| Existing G4 owner needing a second speaker | Price a second compatible channel and recorder inputs | Complete receiver/input/power requirement, not one extra lavalier |
This is why I start with the destination device and speaker count. Once those are fixed, the package list becomes clear. Buying around a single headline such as range or float recording can leave you with no practical way to capture both people, monitor the camera or power the kit through the session.
User Experience and Performance
Real-World Application for Content Creators
My preference for DJI on small creator projects comes from handling: small clips, a compact receiver and a case that keeps the main components together. That makes it easier to move between short pieces to camera and an interview without building a larger audio rig. I would still check placement and record a sample before committing the conversation.
The G4 approach suits a deliberate lavalier setup. Cable dressing and receiver settings take attention, but keeping a small capsule near the speaker can be preferable to displaying a larger transmitter. The useful question is whether that approach suits your subjects and crew. It does not follow that every professional job needs G4 or every beginner should avoid it.
Audio Recording and Output for Filmmakers
For either system, keep the capsule near the intended speaker, protect it appropriately outdoors and check for clothing noise. Noise processing can change how a voice sounds; listen to the result in the actual setting before leaving it enabled for an entire shoot. Good source placement reduces work that no menu setting can reliably undo.
With DJI, verify that internal recording is actually running, then export a sample and confirm your editor can open it. Identify the transmitter files for each speaker and keep them with the camera recording until delivery and backup are complete. The existence of a backup feature is different from having a usable backup of that take.
With G4, the camera or external recorder is the recording destination. Check its record status, available space and channel setup as well as RF reception. If the production requires independent backup audio, budget and plan that separately. Do not assume that a receiver display or a transmitter’s power light means a file is being saved.
Reliability and Interference Management
DJI quotes up to 250 metres under FCC conditions or 160 metres under CE conditions in an unobstructed, interference-free setting. Sennheiser quotes up to 100 metres for this G4 system. These are manufacturer conditions, not my matched walk-away test or a guarantee inside a crowded building.
Walk the actual route with the subject wearing the transmitter, listen at the recorder and include the positions where a body, wall or camera rig obstructs the path. With G4, use an appropriate legal band and sensible frequency coordination. With DJI, consider nearby 2.4 GHz activity. If a take matters, improve the setup or shorten the working distance rather than trusting a maximum-range claim.
For sensitive speech, do not infer encryption or a security advantage from a brand’s reputation. The analogue G4 kit should not be described using the security features of other digital Sennheiser ranges. Confirm the exact system’s suitability with the production’s requirements before recording confidential material.
Conclusion and Personal Recommendation
Best Use Cases
DJI Mic 2 remains my recommendation for most small creator setups in this comparison. The two-transmitter option, internal recording and flexible receiver connections solve practical problems for interviews and work divided between a camera and phone. Choose the complete package that matches your devices, then practise exporting and using the backup files.
Choose the ew 112P G4 kit when its camera-lavalier workflow fits your existing equipment. Replaceable AA power, a separate lavalier and UHF setup can be useful, especially if you already understand the controls and own compatible accessories. Confirm the band, condition and complete recording path. It is not a substitute for researching a newer Sennheiser digital system with different requirements.
Alternatives
If the deciding feature is internal backup, compact two-person recording or a particular connector, compare exact competing kits using that requirement. Our DJI Mic 2 vs Lark Max comparison and Rode Wireless Pro comparison cover other choices. Check model generations and complete-package costs rather than carrying a brand-level ranking across unrelated products.
For an existing G4 owner, replacing a damaged cable or suitable lavalier may solve the problem more economically than changing systems. For a new buyer, include the second-speaker, phone-interface and power requirements before judging price. A cheap incomplete used kit can cost more to make usable than a complete alternative.
Final Word
I would choose DJI for its compact creator workflow, while keeping G4 on the shortlist for a specific camera-lavalier job. Neither choice removes the need for a short recording check. Confirm the right voices reach the right channels, monitor the saved clip, verify the backup plan and make sure the power arrangement covers the session. Those steps make the purchase useful.
Frequently Asked Questions
What distinguishes the audio quality between the DJI Mic 2 and Sennheiser models?
Compare the exact G4 camera-lavalier kit rather than the whole Sennheiser range. Mic placement, the lavalier, gain path and recording device affect dialogue. DJI offers internal recording and optional noise processing; the analogue G4 kit feeds a separate recorder. Neither published frequency response nor brand reputation proves a better listening result.
What improvements does the DJI Mic 2 offer over its predecessor?
Mic 2 adds internal 32-bit float recording, intelligent noise cancelling and a different receiver control layout. Its components and phone adapters are not interchangeable with the original DJI Mic. Check the exact package and connection mode rather than assuming every feature works over Bluetooth.
How does the battery life of the DJI Mic 2 compare to that of similar microphones?
DJI specifies up to six hours per transmitter and receiver under its stated test conditions, with about 18 hours total across case recharges. That is not six plus an additional 18 hours, or an uninterrupted 18-hour take. G4 specifies typical eight-hour operation with suitable AA batteries in each unit.
What is the operational range of the DJI Mic 2 in typical usage scenarios?
DJI’s published maximum is 250 metres under FCC conditions or 160 metres under CE conditions, with no obstruction or interference. Walls, bodies and radio activity can reduce the useful distance. Check the actual route while monitoring and recording; these figures are not a matched test against G4.
Are there any notable advancements or features in the DJI Mic 2 that stand out?
Internal 32-bit float files, two-transmitter receiver operation and compact controls are useful features. Each transmitter stores up to 14 hours at 24-bit or about 11 hours at 32-bit float, but storage is separate from battery life. Internal recording and intelligent noise cancelling are unavailable in Bluetooth smartphone mode.
