If you want a wireless in-ear monitor system for mobile, personal listening during video calls, choose Phenyx Pro UHF Mono; if you need a desk-based studio bundle for recording and listening through speakers, choose M-AUDIO BX4.
These products solve different audio problems, so my choice comes down to how you work: Phenyx Pro provides a wireless bodypack receiver and mono monitoring, while M-AUDIO combines studio monitors, headphones, and a dual XLR interface. Neither is a dedicated video-call headset, but one is built to move with you and the other to support a home-studio setup.
• Phenyx Pro UHF Mono’s biggest strength: wireless in-ear monitoring with 50 selectable UHF frequencies and an operating range of up to 164 feet. Trade-off: it provides mono monitoring, not stereo.
• M-AUDIO BX4’s biggest strength: a home-studio bundle with monitors, headphones, a dual XLR interface, and Bluetooth connectivity. Trade-off: its speaker-based setup is less suited to moving around during a call.
• Choose Phenyx Pro if you need personal wireless monitoring and freedom to move around a stage, room, or event space.
• Choose M-AUDIO BX4 if you need speakers and recording connections for a stationary home studio, podcast, or streaming setup.
The Phenyx Pro PTM-11 is a wireless in-ear monitor system, not a conventional gaming headset or a pair of open-ear earbuds. Its transmitter sends audio to a bodypack receiver, letting the listener monitor through the included earphone without staying beside the sound source. The system works in the UHF 900 MHz band, offers 50 selectable frequencies, and has a stated operating range of up to 164 feet. The specifications note that walls, glass, and metal can interfere with longer-distance use.
Its mono design is a practical choice when a clear, focused personal mix matters more than stereo separation. The transmitter has left and right inputs, separate line outputs, and a PAD switch intended to reduce overly strong input signals. One transmitter can support multiple receivers, and the system can accommodate up to five IEM systems working together. That makes it a more natural fit for performers, hosts, or presenters who need monitoring in a live or shared setting than for someone seeking a simple plug-in headset for casual calls.
For video calls, the appeal is mobility: an in-ear receiver lets you listen without being tethered directly to a desk. But the listed features do not establish that this system is a complete call headset with a microphone, computer-call controls, or stereo sound. I would skip it if those are the main things you want, or if you specifically want an open-ear listening style. Despite searches for “hifi stereo open ear earbuds for video calls,” this is a mono in-ear monitor system, not that kind of product.

The M-AUDIO BX4 bundle is aimed at people building a home audio workspace. It includes studio monitors, a dual XLR audio interface, and headphones, with Bluetooth connectivity for streaming music to the monitors. The product information positions the monitors for detailed listening and mixing, while the interface supports recording multiple sources. Together, those features are more relevant to music production, podcasting, and streaming than to portable personal monitoring.
The bundle’s biggest advantage is that it brings several studio components into one setup. Someone recording a podcast or streaming at a desk can connect audio sources through the interface, listen through the monitors, and use the included headphones for more isolated monitoring. Bluetooth adds another way to play music through the speakers. That combination gives the BX4 a wider studio role than a standalone headset, but it also assumes you want speakers and a fixed listening area.
For video calls, the BX4 may make sense as part of a desk-based workspace if you want speaker playback and also have a separate way to handle your call microphone. The listed details do not identify it as a wireless headset or specify a microphone built into the headphones, so I would not buy it expecting a ready-to-wear call solution. People searching for the “best wireless gaming headset for video calls” or the “best gaming headset for video calls” should note the mismatch: this is a studio monitor bundle, not a gaming headset.
• Best for moving around while listening → Phenyx Pro UHF Mono. Its bodypack receiver and stated 164-foot operating range are designed for wireless monitoring, with the caveat that physical obstructions can affect longer-distance use.
• Best for a desk-based studio → M-AUDIO BX4. It combines monitors, headphones, and a dual XLR interface in one bundle.
• Best for mono personal monitoring → Phenyx Pro UHF Mono. The system is explicitly designed for mono listening, with left and right inputs and separate line outputs.
• Best for recording multiple sources → M-AUDIO BX4. Its dual XLR interface is described as supporting simultaneous recording of multiple sources.
• Best for a live performance or presentation setup → Phenyx Pro UHF Mono. The transmitter, receiver, multiple selectable frequencies, and support for multiple receivers align with stage and event monitoring.
• Best for Bluetooth music playback through speakers → M-AUDIO BX4. Its monitors include Bluetooth connectivity for wireless music streaming.
• Best for a video-call listener who needs freedom to move → Phenyx Pro UHF Mono, with a caveat. Its wireless monitoring format supports movement, but the listed features do not make it a complete microphone-equipped call headset.
• Best for a video-call workspace that also serves as a recording or streaming desk → M-AUDIO BX4. The interface and monitoring gear suit that broader workflow, though the data does not specify a built-in call microphone.
I would choose the Phenyx Pro UHF Mono if my priority were moving freely while listening during video calls or presentations. Its wireless bodypack setup and 164-foot stated range make it the more relevant of these two for mobile monitoring, though it is mono and isn’t specified as a complete call headset.
If I were building a stationary production desk, I’d choose the M-AUDIO BX4 instead. Its monitors, headphones, dual XLR interface, and Bluetooth address more studio tasks. For video calls specifically, my pick is Phenyx Pro—but only when wireless listening matters more than having an all-in-one headset.
FAQ
It may suit someone who wants wireless in-ear monitoring and room to move. The listed features do not specify a built-in microphone or dedicated computer-call controls, so don’t assume it replaces a full headset.
The M-AUDIO BX4 is the more directly suited option because the bundle includes studio monitors, headphones, and a dual XLR interface for recording multiple sources. The Phenyx Pro is built around wireless in-ear monitoring instead.
The M-AUDIO BX4 bundle is the more appropriate direction if you want speaker-based studio listening, but the supplied details do not specify a particular stereo configuration. The Phenyx Pro system is explicitly mono, so it is not the right choice for stereo in-ear monitoring.
