If you want over-ear headphones for big ears, choose Yamaha HPH-MT120BL; if you need a wireless in-ear monitor system for live performance, choose LMBGM UHF. The Yamaha’s over-ear, closed-back design makes it the more relevant option for shoppers who prioritize room around the ears. The LMBGM is built around wireless stage monitoring, not over-ear comfort.
Yamaha HPH-MT120BL vs LMBGM UHF at a Glance
• LMBGM UHF: Wireless in-ear monitoring with 16 selectable channels, mono/stereo switching, and a stated range of up to 164 feet; the trade-off is an in-ear fit and battery-powered operation.
• Yamaha is for listeners who want a conventional over-ear headphone design and do not need wireless monitoring.
• LMBGM is for performers who need to hear an audio feed while moving around a stage, rehearsal space, or studio.
• Neither product’s listed specifications establish a particular fit for every ear; for big ears, the Yamaha’s over-ear format is the more sensible place to start.
The Yamaha HPH-MT120BL is a wired, over-ear headphone with a closed-back design and dynamic 40 mm drivers. Its listed frequency range is 20 Hz to 22,000 Hz, and its sensitivity is 96 dB SPL. Those figures describe the product, but they do not tell me exactly how it will sound to each listener or how much room its earcups provide.
For someone searching for headphones for big ears, the over-ear format is the relevant distinction. It places the earpieces around the ears rather than inside them, which may be a better starting point than an in-ear monitor if you dislike having earpieces inserted into your ears. Still, the product information does not give earcup dimensions, so I would not assume a guaranteed fit based on the design label alone.

The 3.5 mm jack and wired connection make the Yamaha a straightforward option for listening from compatible equipment without depending on a wireless link or listed battery runtime. Skip it if your main need is wireless freedom during a live performance: it is a wired headphone, not a UHF transmitter-and-receiver system. It is also not described as having a built-in microphone or Bluetooth, so shoppers looking specifically for “with microphone bluetooth headphones for big ears” should not treat this model as meeting those requirements.
The LMBGM UHF is a wireless in-ear monitor system aimed at stage, studio, rehearsal, and vocal-coaching use. It uses RF wireless technology in the 572.5–587.5 MHz range and offers 16 selectable channels. The system is specified for a range of up to 164 feet, with latency under 5 ms. These are features for sending an audio monitor feed to a performer, not the usual setup for casual Bluetooth listening.
It can switch between mono and stereo, with independent left- and right-channel control. That gives performers flexibility over how they receive their monitor signal. A 3.5 mm input and output are listed for connecting with mixers, instruments, and headphones. The system’s TFT display shows channel, frequency, and battery status, which is useful information when setting up or checking a wireless monitor connection.
The trade-off is that this is an in-ear system. Its lightweight, tilt-fit design is intended for extended wearing, but the listed information does not give earbud dimensions or establish that it will suit unusually large ears. Battery life is listed as up to six hours for the transmitter and four to six hours for the receiver; a full charge is specified at about three to four hours in the feature details. If you want simple over-ear headphones for listening at a desk, or gaming headphones for big ears, the LMBGM is a specialized and less direct fit. It is not described as a Bluetooth headset or as having a microphone.
• Want an over-ear design for big ears? → Yamaha HPH-MT120BL. It goes around the ears, while the LMBGM is explicitly an in-ear system. Since neither sheet gives earcup or earpiece dimensions, fit still cannot be guaranteed from the format alone.
• Need wireless audio for a performer? → LMBGM UHF. Its transmitter-and-receiver system uses RF, with 16 selectable channels and a stated range up to 164 feet.
• Prefer a simple wired headphone connection? → Yamaha HPH-MT120BL. It has a 3.5 mm jack and does not require the battery-powered wireless setup described for the LMBGM.
• Need to switch between mono and stereo monitoring? → LMBGM UHF. Those modes are part of its stated functionality, along with independent left- and right-channel control.
• Need a listed frequency range for headphone playback? → Yamaha HPH-MT120BL. Its range is 20 Hz–22,000 Hz; the LMBGM’s listed range is 20 Hz–20,000 Hz.
• Have a limited stretch between charges? → Consider the Yamaha. The LMBGM lists four to six hours for the receiver and up to six hours for the transmitter, while the Yamaha is wired and has no battery runtime listed.
• Shopping for Bluetooth headphones with a microphone? → Neither is a clear match. The Yamaha is wired, and the LMBGM uses RF; neither product information sheet lists a microphone or Bluetooth.
• Looking for extra bass in ear headphones for big ears? → Neither sheet confirms that combination. The LMBGM is in-ear, but no specific extra-bass tuning is listed; the Yamaha is over-ear, not in-ear.
I would choose the Yamaha HPH-MT120BL if my priority were an over-ear headphone for big ears, because its format is the closer fit for that need and its wired setup is uncomplicated. I would choose the LMBGM UHF only when wireless in-ear monitoring, mono/stereo selection, and stage-oriented use mattered more than over-ear comfort. For big ears, my recommendation is the Yamaha—but the missing earcup dimensions mean I would not assume every wearer will get a roomy fit.
