Plantronics M25 Bluetooth Headset
Our M25 represents pure simplicity in wireless communication. This compact headset delivers up to 11 hours of talk time on a single charge, keeping you connected through back-to-back calls without interruption. The Deep Sleep mode activates after an extended period away from your phone, preserving battery life for months between uses.
We built the M25 with everyday reliability in mind. The ergonomic eartip rotates 180 degrees for either-ear wearing, and the soft gel tip conforms gently to your ear canal for hours of comfortable use. Voice commands let you answer, ignore, or redial calls without touching a button. Whether you’re driving, working from home, or managing a busy schedule on the move, the M25 adapts to how you communicate.
M25 technical highlights
Battery life and power management
The M25 runs for 11 continuous hours of talk time on a full charge, which translates to roughly a week of typical daily use for most professionals. When you’re away from your phone for an extended period, Deep Sleep mode kicks in automatically, dropping power consumption to near zero. We’ve tested units that remained in Deep Sleep for over five months and powered on instantly when reconnected.
Charging takes about 90 minutes from empty to full using the included micro-USB cable. A quick 10-minute charge provides roughly an hour of talk time when you’re in a rush. The voice prompt announces remaining talk time when you power on, so you always know whether you need to top up before heading out.
Comfort and wearing options
We designed the earbud assembly to rotate a full 180 degrees, letting you switch ears mid-call or wear the headset on whichever side feels more natural. The soft silicone gel tip comes in three sizes to match different ear canal dimensions. Most users find the medium tip provides a secure seal without pressure.
Secure fit during movement
The eartip hooks gently into the outer bowl of your ear rather than relying solely on canal insertion. This approach distributes contact across a wider surface area, reducing fatigue during extended wear. We’ve heard from drivers, warehouse supervisors, and field technicians who wear the M25 for eight-hour shifts without discomfort. The 7-gram weight disappears once the unit is seated properly.
Voice commands and call handling
Say “Answer” or “Ignore” when a call comes in, and the M25 responds without requiring you to press anything. The “Redial” command reconnects you to the last number you called. These voice prompts work reliably in quiet to moderate noise environments. Heavy wind or loud machinery can reduce recognition accuracy, but the multi-function call button provides a manual fallback.
Multipoint pairing lets you connect the M25 to two devices simultaneously. When a call arrives on either phone, the headset announces which device is ringing so you can decide whether to take it. Switching between devices happens automatically based on which one has an active call.

Common questions about the M25
The M25 provides 11 hours of continuous talk time and up to 16 days of standby on a single charge. If you don’t use the headset for an extended period, Deep Sleep mode activates automatically and preserves the battery for months. Most users charge once per week with typical daily call volumes.
Yes, the M25 supports multipoint pairing for two Bluetooth devices simultaneously. When a call comes in, the headset announces which device is ringing so you can decide whether to answer. You can switch between devices without manual re-pairing.
The M25 focuses on voice calls and does not support A2DP audio streaming for music or podcasts. You’ll hear audio from calls and voice prompts only. If you want to stream media alongside calls, our M50 model includes A2DP for music and GPS directions.
The M25 features a P2i nano-coating that protects internal components from moisture, sweat, and light rain. It is not rated as waterproof and should not be submerged or exposed to heavy downpours. The coating handles everyday humidity and perspiration without issue.
The M25 includes small, medium, and large soft gel eartips. Most users find the medium tip provides a comfortable seal, but try all three to see which feels most secure. The eartip should rest gently in your ear canal without pressure. If it falls out during movement, step up one size.
Voice commands are always active when the headset is powered on and connected. When a call arrives, say “Answer” or “Ignore” clearly. To redial the last number you called, say “Redial” when no call is active. The multi-function button provides a manual fallback if voice recognition doesn’t respond.
Yes, the earbud rotates 180 degrees so you can wear the M25 on your left or right ear. Rotate the eartip boom until the microphone points toward your mouth, then hook the gel tip gently into your ear. You can switch ears mid-call without disconnecting.
