The wireless boom microphone is one of those things we get asked about regularly. Especially when VMK25 headphones are used at work and colleagues complain that you sound like you’re speaking from the bottom of a well. A perfectly understandable concern.
Unfortunately, the answer isn’t what you’d hope.
VMK25 does not support the wireless boom microphone
The wireless boom microphone is an accessory that works only with the VMK25.2 model. It attaches via the USB-C port and requires the newer model’s firmware to operate.
VMK25 is an excellent pair of headphones – which is why it’s been selling like hotcakes – but its USB-C port is for charging only. The microphone add-on wasn’t designed for the original model because it simply didn’t exist back then.
So, in short:
- VMK25 – does not support the wireless boom microphone
- VMK25.2 – supports the wireless boom microphone (accessory, sold separately)
What about the VMK25’s built-in microphone?
The VMK25 has a built-in microphone with CVC8 noise reduction. It handles regular calls and Teams meetings just fine as long as conditions are reasonable. A quiet office or home office – no problem. A noisy open-plan office or café – that’s where it starts to reach its limits.
If your colleagues have complained about your voice quality, try these first:
- Check the Bluetooth connection – if the headphones are connected to two devices (multipoint), the quality of the talk microphone may suffer. Disconnect the other device for the duration of the call.
- Check the app’s settings – Teams, Zoom, and others sometimes like to pick the wrong microphone. Make sure the headphones are selected as both the speaker and the microphone.
- Distance to the phone/computer – keep the device reasonably close. Bluetooth doesn’t like walls and long distances.
If you need a better microphone
You have two options:
- Upgrade to the VMK25.2 model and buy the wireless boom microphone as an accessory. You’ll also get improved battery life (55h vs. 50h) and a newer Bluetooth 5.4 chipset. The headphones look the same on the outside, but the internals are new.
- Use a separate desktop microphone with your computer and keep the VMK25 for listening only. This is, honestly, the best solution if you don’t want to buy new headphones.
We don’t push unnecessary upgrades, but if microphone quality is critical for work, VMK25.2 + the wireless boom microphone is a combination that gets the job done. That’s just how it is.
Anything else?
If you’re not sure which model you have, check the batch code on the inside of the headphones. The VMK25.2 model says "VMK25.2" and the older one says "VMK25". If the text has worn off, send us a message at info@valco.fi and we’ll figure it out. At the same time, we can calculate how much closer we are to the Death Star if you decide to upgrade.
