If you want a wired, dual-mic USB headset built for all-day desk work with active noise cancellation and a Teams-optimized design, choose Yealink UH37; if you need an open-ear, wireless headset that keeps your ears free for your surroundings with a lightweight bone-conduction build, choose ShenzhenShokzCo.Ltd OpenComm2.
• Yealink UH37 biggest strength: Dual noise-canceling microphones with Acoustic Shield technology, professional-grade 35mm stereo speakers, and dynamic EQ that switches between call and music mode.
• Yealink UH37 biggest trade-off: Wired USB-only connection, so you are tethered to your PC or laptop with no wireless freedom.
• ShenzhenShokzCo.Ltd OpenComm2 biggest strength: Bone conduction open-ear design weighing only 35g, with up to 16 hours of talk time and a 5-minute quick charge giving 2 hours of talk time.
• ShenzhenShokzCo.Ltd OpenComm2 biggest trade-off: Open-ear design means no active noise cancellation, and it relies on Bluetooth or the Loop120 adapter rather than a direct wired connection.
• Who Yealink UH37 is for: Office, call center, and desk-based professionals who want focused, immersive audio in a fixed workstation setup.
• Who ShenzhenShokzCo.Ltd OpenComm2 is for: Mobile workers and hybrid professionals who move around and want to stay aware of their environment while on calls.
The Yealink UH37 is a wired USB headset that leans hard into call clarity. Its standout feature is the dual noise-canceling microphone setup paired with Yealink's Acoustic Shield technology, which is designed to shield background noise and pick up only the speaker's voice. In a crowded office or a busy home workspace, that combination is meant to cut interference on both ends of a call. If your priority is being understood clearly on every call, this is the part of the design that matters most.
Buy the Yealink UH37 if you work primarily at a desk, take a lot of calls, and want a single wired connection you can trust. It is compatible with Windows and macOS, and it is certified for major voice platforms, so software integration on a PC or laptop is straightforward. Skip it if you need to walk around during calls, want wireless freedom, or prefer an open-ear design that lets you hear your surroundings. This is a tethered, workstation-first headset.
ShenzhenShokzCo.Ltd OpenComm2: Who It's For
The ShenzhenShokzCo.Ltd OpenComm2 is a very different animal: an open-ear, bone-conduction headset built for mobility. At just 35g, it is one of the lightest designs in this comparison, and it uses a flexible frame with an IP55 water-resistant soft silicone finish. That combination is aimed at people who wear a headset for hours and move between rooms, floors, or even outdoors. Because it sits outside the ear canal rather than over it, your ears stay open to your surroundings — useful in a shared office, at home, or anywhere you need situational awareness.
For calls, it relies on Shokz 7th-generation bone conduction technology, PremiumPitch 2.0 audio, and a noise-canceling microphone with DSP. The frequency range runs from 20 Hz to 20,000 Hz, broader on paper than the Yealink, though bone conduction delivers sound differently than traditional drivers. Connectivity is wireless via Bluetooth 5.1 with a 98-foot range, and the included Shokz Loop120 USB-C adapter is designed to keep a PC or Mac connection stable. It is Zoom-certified, and physical buttons handle volume, mute, and play/pause.
Battery is a headline here: up to 16 hours of talk time and 8 hours of listening time per charge, with a 5-minute quick charge yielding 2 hours of talk time. A full charge takes about 1 hour. Buy the OpenComm2 if you are a hybrid or mobile worker who wants wireless freedom, light weight, and open-ear awareness. Skip it if you need active noise cancellation to block out a noisy room, or if you prefer the guaranteed stability of a wired USB connection with no charging to think about.
• Best for call clarity in a noisy office → Yealink UH37. Dual noise-canceling mics plus Acoustic Shield target voice pickup directly.

• Best for a fixed desk setup with zero charging hassle → Yealink UH37. Wired USB means no battery to manage.
• Best for staying aware of your surroundings → ShenzhenShokzCo.Ltd OpenComm2. Open-ear design keeps your ears free.

In my opinion, the right pick comes down to how you work, not which headset is "better." If you sit at a desk, take back-to-back calls, and want maximum call clarity with no charging to worry about, I would buy the Yealink UH37 — its dual noise-canceling mics, dynamic EQ, and wired reliability fit that life perfectly. If you move around, want to stay aware of your surroundings, and value a 35g open-ear build with long battery life, I would buy the ShenzhenShokzCo.Ltd OpenComm2 instead. One is a workstation tool; the other is a mobile companion. Match it to your day and you will be happy either way.
