If you want a shared, low-latency listening setup for a call center, choose Avantree Quartet 2; if you need open-ear Bluetooth audio with a hands-free camera for active use, choose VibeLens MusicCam Bone Conduction. For a team listening to the same audio, Quartet 2 is the more relevant fit. For someone who wants to move around while keeping their ears uncovered and recording a point-of-view video, MusicCam is built for a different job.
Avantree Quartet 2 vs VibeLens MusicCam Bone Conduction at a Glance
• VibeLens MusicCam Bone Conduction: Its open-ear Bluetooth design combines audio with 1080P hands-free recording; the trade-off is that it is a single-user wearable, not a multi-headphone listening system.
• For shared listening: Quartet 2 suits households, classrooms, and groups that need the same audio in multiple headsets.
• For active individual use: MusicCam suits people who want to listen and capture a first-person view while walking, cycling, or doing other activities.
• For call-center-style group audio: Quartet 2 is the more practical match when several people need to hear one source; neither product sheet describes dedicated call-center features such as a boom microphone.
Avantree Quartet 2 is a wireless group-listening system built around a transmitter and four over-ear headphones. Connect the transmitter to a compatible source using Optical, AUX, or Bluetooth, then share that audio among the included headsets. The system uses a 2.4GHz link, and each listener can adjust their own headphone volume without changing anyone else’s level.
That setup makes the Quartet 2 a stronger candidate for a room where several people need to follow the same material: a training session, a classroom activity, a family movie, or a church gathering. The system can also expand to as many as 100 users with compatible additional headphones. For a call center, that group-oriented design may make sense when the task is listening together to a shared source—not when each agent needs an independent headset and microphone for separate calls.
How We Research

VibeLens MusicCam combines open-ear Bluetooth audio with a built-in camera for hands-free point-of-view recording. Its listed camera resolution is 1080P, and six-axis stabilization is intended to reduce movement in recorded footage. The wraparound frame weighs 50 g and has soft silicone contact areas, while the open-ear design leaves the ears uncovered during listening.
That combination is aimed at an individual who wants audio and video capture in one wearable while walking, cycling, hiking, or exercising. It pairs with iOS or Android devices over Bluetooth and uses app and button controls for recording. Those details make it a more natural choice for active outings than a transmitter-based over-ear system.
But MusicCam is not a shared-listening solution. It does not come with a transmitter and multiple headphones, and its listed features do not describe a call-center microphone or multi-user audio setup. I would skip it if your priority is sending one audio feed to several listeners or giving each person a separate volume control. It is aimed at personal mobility and recording, not group monitoring.

Its included transmitter and headsets are designed to work together without direct Bluetooth pairing between the headphones and a phone.
The wording shoppers use can blur very different products together. Someone searching for the best on ear headphones for call center may mean a headset for individual calls, but Quartet 2 is specifically an over-ear group-listening system, not a dedicated agent headset. Someone looking for the best open ear headphones for call center may value awareness, which points toward MusicCam’s open design, but the listed details do not identify a call-center microphone. And best clip on earbuds for call center is not quite the right description for either product: Quartet 2 is over-ear, while MusicCam uses a wraparound open-ear frame.
I would choose Avantree Quartet 2 if my priority were shared audio for a call-center-style training or listening session. Four included headphones, separate volume controls, and the option to expand the system are more useful for that job than MusicCam’s camera and outdoor-focused design. For individual calls, I would look for a product whose specifications explicitly describe call-center use and a microphone. But between these two, Quartet 2 is my pick for group listening in a call-center setting.
No. The headphones connect through the included transmitter and its 2.4GHz wireless link; they are not designed to pair directly with a phone or tablet as Bluetooth headphones. The transmitter can connect to a source using Optical, AUX, or Bluetooth.
Its open-ear Bluetooth audio may suit someone who wants to hear surrounding sounds while listening, but the listed features do not describe a dedicated call-center microphone or shared multi-user audio. For several people listening to one source, Quartet 2 is the closer fit.
MusicCam is the purpose-built option for that use. It combines open-ear audio with hands-free 1080P recording, six-axis stabilization, and listed IP68 protection for specified outdoor and water activities.
The system includes four headphones and can expand to as many as 100 users with compatible additional headphones. Each listener can adjust their own volume without changing the levels for others.
