Audio performance and noise reduction
Two precisely tuned microphones work together to isolate your voice from surrounding noise. The first mic captures your speech while the second samples ambient sound, then our enhanced DSP chip subtracts the unwanted frequencies in real time. This dual-mic array handles wind, traffic, and office chatter without requiring you to raise your voice or cup your hand over the mic.
Wideband audio support reproduces frequencies up to 6.8 kHz, nearly double the range of standard phone audio. Callers hear the natural tone and clarity of your voice instead of the muffled, compressed sound common on older Bluetooth devices. The M25 automatically adjusts volume based on background noise levels, so you don’t manually tweak settings mid-conversation.
Battery life and Deep Sleep technology
When you place the M25 on its charger or power it off manually, Deep Sleep mode kicks in after two hours of inactivity. This hibernation state draws only a trickle of power, preserving enough charge for up to five months of standby. The moment you pick up the headset or press the call button, it wakes instantly and reconnects to your phone within three seconds.
A full 90-minute charge from empty delivers 11 hours of continuous talk time or 10 days of active standby. The battery meter announces remaining time when you power on, and voice alerts warn you 10 minutes before shutdown. If you’re in a rush, a 20-minute quick charge provides two hours of talk time to get you through urgent calls.
Multipoint pairing and device switching
The M25 maintains active Bluetooth connections to two phones or tablets at once, eliminating the need to unpair and re-pair when you switch devices. We designed this multipoint feature for professionals who carry separate work and personal phones, or anyone who shares a tablet and smartphone throughout the day.
Incoming calls ring through from whichever device is calling, and you answer with a single button press. If you’re already on a call when the second device rings, the M25 holds the active call and alerts you to the new incoming line. You can ignore the second call or switch between them using the multipoint button. The headset remembers the last two paired devices and reconnects automatically when they come into range.

Common questions about the M25
The M25 delivers up to 11 hours of continuous talk time or 10 days of active standby on a full 90-minute charge. When you activate Deep Sleep mode by powering off or docking the headset, standby time extends to five months. A quick 20-minute charge provides approximately two hours of talk time for urgent calls.
Yes, multipoint technology lets the M25 maintain active Bluetooth connections to two devices simultaneously. You can answer calls from either phone with a single button press, and the headset automatically reconnects to the last two paired devices when they come into range. This feature is ideal for managing separate work and personal phones without manual switching.
The M25 is fully compatible with Siri, Google Assistant, and Cortana. Press and hold the call button for two seconds to activate your phone’s voice assistant, then speak your command. You can dictate messages, set reminders, ask for directions, or control music playback without touching your phone.
Every M25 ships with the headset, three soft gel ear tips in small, medium, and large sizes, a USB charging cable, and a quick-start guide. The package does not include a wall adapter, but you can charge the headset using any standard USB port on a computer, car charger, or phone adapter.
Deep Sleep activates automatically after two hours of inactivity when the M25 is powered off or placed on its charger. This hibernation state draws minimal power to preserve battery for up to five months. The headset wakes instantly when you press any button or remove it from the charger, reconnecting to your phone within three seconds.
At 0.3 ounces, the M25 is one of the lightest Bluetooth headsets available. The curved earhook distributes weight across the back of your ear rather than pressing into the canal, and the three included ear-tip sizes let you customize the fit. The rotating earhook adjusts to either ear and angles the speaker for optimal alignment.
The M25 uses two microphones with enhanced DSP processing to isolate your voice from ambient sound. One mic captures your speech while the second samples background noise, then the DSP chip subtracts unwanted frequencies in real time. This system handles wind, traffic, and office chatter effectively, though it’s not designed for extremely loud environments like construction sites.
