How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a business Bluetooth headset that doubles as an all-day UC workstation companion with a boom mic, flip-to-mute and a dongle in the box, choose Yealink BH70; if you need a lightweight in-ear Bluetooth headset with a pocket charging case and dual noise-cancelling mics for calls on the move, choose COMEXION Headset V5.3.
• Yealink BH70 — biggest strength: a proper on-ear business headset with a flip-up boom mic, 3 MEMS mics with acoustic shield noise blocking, a Busy Light, and up to 35 hours of talk time (43 hours music) via Bluetooth 5.1 with a BT51 dongle and 50 m range.
• Yealink BH70 — biggest trade-off: it is an on-ear mono headset built for desk and softphone work, so it is not something you tuck in a pocket, and the full feature set lives in the Yealink USB Connect client rather than being plug-and-play for everyone.
• COMEXION Headset V5.3 — biggest strength: an in-ear, hook-style headset with dual noise-cancelling microphones, Bluetooth 5.3, an included dongle, and a 500 mAh charging case that lets you top up on the go.
• COMEXION Headset V5.3 — biggest trade-off: a 30 ft Bluetooth range, a 2-hour charge time, no headphone jack, and only a single eartip set with left/right wear options — it is a call headset first, not a music-first or all-day desk headset.
• Who each is for: pick the BH70 if you live in Teams, Zoom, Webex or Cisco Jabber meetings at a desk; pick the COMEXION V5.3 if you want a discreet in-ear headset for phone calls, driving, deliveries or roaming around an office.
The BH70 is a work headset in the traditional sense. It sits on your ear rather than inside it, weighs about 90 g, and pairs a 35 mm dynamic driver with 140 ohm impedance. The mic arm flips up to mute — faster than hunting for a button — and there is also a physical mute button with an LED indicator that syncs with Teams and Zoom, plus an audio confirmation so you never talk into a muted mic. If you have ever delivered half a sentence before realising you were muted, that detail matters more than it sounds.
Where it earns its place is the open office and the home office with background noise. Yealink's acoustic shield technology uses 3 MEMS microphones to block background noise while you speak, so keyboard clatter, a busy household or a shared workspace gets pushed down without cutting off what reaches your ears. There is also a Busy Light that signals to colleagues you are on a call, which is a small thing that saves a lot of awkward interruptions.
Battery is the headline number: up to 35 hours of talk time and 43 hours of music, with a 90-minute charge. For remote call centre agents, support staff and anyone whose day is back-to-back calls, that is the difference between charging nightly and charging whenever you remember. Connectivity is Bluetooth with a BT51 dongle (USB-C to A) for the computer, plus simultaneous phone and PC pairing, and a 50 m wireless range. It is UC-optimised across platforms and now works with Cisco Webex and Jabber, including answer, hang up and mute from the headset.
Buy it if you want one headset for meetings, softphone calls and music at a desk, and you value the boom mic, mute ergonomics and long battery. Skip it if you want something pocketable for calls in the car or on a warehouse floor — that is simply not what an on-ear 90 g headset is for.
The COMEXION V5.3 goes the other way entirely. It is an in-ear, hook-style headset with a 32 ohm driver, a 20 Hz – 20,000 Hz frequency range, and Bluetooth 5.3 for stable, anti-interference connections — handy in crowded wireless environments with lots of devices around. It ships with a one-to-one dongle for computers, and if you are already connected to one device you can hold the mute button for 5 seconds to enter pairing mode and add a second device, then switch between them. A single click on the mute button mutes the call.
The dual-microphone setup with an upgraded noise-cancelling chip targets exactly the noises that ruin mobile calls: subway rumble, wind, keyboard tapping. That makes it a natural fit for truckers, delivery drivers, field staff and anyone taking calls while moving. It is also a genuinely practical pick for people who dislike wearing something over their ear for eight hours — you get different eartip sizes at the bottom of the box compartment and can wear it on either ear.
The 500 mAh charging case is the real differentiator. You are not tied to a desk to charge; drop the headset in the case in your bag and top it up as you go. There is even a slot inside for the dongle so it does not go missing. Two things to weigh honestly: the 30 ft Bluetooth range is far shorter than the BH70's 50 m, and charging takes 2 hours. There is also no headphone jack, so this is a Bluetooth-only device.
Buy it if you want a light, discreet in-ear headset for phone and computer calls, value the pocketable charging case and travel-friendly design, and do not need a boom mic. Skip it if your day is long video meetings at a fixed desk and you want the mute ergonomics, Busy Light and 35-hour talk battery of a dedicated UC headset.
• Best for all-day talk battery → Yealink BH70. Up to 35 hours of talk time versus a standby-focused design on the COMEXION; the BH70 is built for people who are on calls continuously.
• Best for desk-based UC meetings → Yealink BH70. The BT51 dongle, simultaneous PC and phone pairing, and Cisco Webex/Jabber support make it the more natural fit for softphone-first workflows.
• Best for mute ergonomics → Yealink BH70. Flip the mic arm up to mute, or use the LED mute button that syncs with Teams and Zoom — plus audio confirmation so you know your state.
• Best for open office and noisy homes → Yealink BH70. 3 MEMS mics with acoustic shield noise blocking, a Busy Light, and active noise cancellation on the ear.
• Best for calls on the move → COMEXION Headset V5.3. In-ear hook design, dual noise-cancelling mics, Bluetooth 5.3 and a dongle make it easy to take calls anywhere.
• Best for charging flexibility → COMEXION Headset V5.3. The 500 mAh case charges the headset in a bag, so you are not chained to a desk or a cable.
• Best for discreet, comfortable long wear → COMEXION Headset V5.3. Multiple eartip sizes and left/right wear options suit people who dislike on-ear pressure.
• Best for wireless freedom around a building → Yealink BH70. Its 50 m Bluetooth range comfortably beats the COMEXION's 30 ft.
In my opinion, the Yealink BH70 is the better business Bluetooth headset for anyone whose calls happen at a desk — the boom mic, flip-to-mute, Busy Light, 35-hour talk battery, 50 m range and Cisco/Teams/Zoom compatibility add up to a tool built for work rather than for convenience. I would buy the COMEXION Headset V5.3 instead if my calls happen in a truck, on a shop floor or between meetings on the move, because the in-ear fit and charging case solve problems the BH70 does not try to solve. Match the headset to where you actually take calls, and either one will do its job well.
how to use business wireless headset
Charge it fully first, then connect it to your computer or phone — the BH70 pairs over Bluetooth and can also use its BT51 dongle, while the COMEXION V5.3 pairs over Bluetooth 5.3 or its one-to-one dongle. After that, use the on-headset controls: the BH70 mutes by flipping the mic arm up, and the COMEXION mutes with a single button click.
how to pair business wireless headset
Put the headset in pairing mode and select it from your device's Bluetooth list. On the BH70 you can pair a phone and a computer simultaneously; on the COMEXION V5.3, if one device is already connected, hold the mute button for 5 seconds to enter pairing mode and connect a second device.
can bluetooth headsets talk to each other
No — Bluetooth headsets are designed to connect to a host device such as a phone, computer or dongle, not to stream audio directly to another headset. Both the BH70 and the COMEXION V5.3 connect to your devices through Bluetooth or their included USB dongles, so two people on two headsets still need a call platform to talk to each other.
what is the difference between these two business bluetooth headsets
The Yealink BH70 is an on-ear UC headset with 3 MEMS mics, a flip-to-mute boom arm, a Busy Light, 35 hours of talk time and 50 m range, aimed at desk and softphone work. The COMEXION V5.3 is an in-ear hook headset with dual noise-cancelling mics, Bluetooth 5.3, a 500 mAh charging case and 30 ft range, aimed at mobile and on-the-go calling.
