Plantronics Marque 2 M165 Bluetooth Headset
We designed the Plantronics M165 to be your everyday wireless companion — compact enough to disappear in your pocket yet powerful enough to handle calls in any environment. This single-ear Bluetooth headset delivers our signature audio clarity through dual-microphone noise cancellation and wideband audio technology.
Whether you’re on conference calls, navigating traffic, or managing back-to-back conversations, the M165 keeps you connected without the bulk. Our engineers optimized every millimeter for comfort and performance, creating a headset that weighs just 7 grams while delivering up to 7 hours of continuous talk time.
Technical specs & what’s included
AudioIQ2 noise cancellation technology
Our dual-microphone system does more than capture your voice — it actively listens to your environment and cancels unwanted sound before it reaches the other end of your call. The M165 employs AudioIQ2 digital signal processing to separate your speech from background chatter, wind noise, and street traffic.
Wideband audio extends the frequency range beyond traditional narrowband telephony, preserving the natural tone and inflection that make conversations feel face-to-face. You’ll hear the difference immediately on your first call — consonants sound crisper, vowels carry more warmth, and the person on the other end won’t ask you to repeat yourself.
DeepSleep mode and battery performance
We built the M165 for people who don’t use a headset every hour of every day. DeepSleep hibernation mode kicks in after the headset sits idle, preserving battery charge for up to six months between uses. When you need it again, a quick press of the call button wakes it instantly.
A full 90-minute charge delivers seven hours of continuous talk time or up to eleven days of active standby. The voice alert system announces remaining battery level when you power on, so you’ll never be caught off-guard mid-conversation. Our engineers chose lithium-polymer cells specifically for their charge retention and compact form factor.
Comfort and moisture resistance
Secure fit options
We include three sizes of soft gel ear tips in the box because every ear is different. The curved earbud design distributes weight across the outer ear rather than relying on pressure inside the ear canal. Most users forget they’re wearing it after the first ten minutes.
P2i nano-coating protection
The entire internal circuit board carries a P2i moisture-resistant treatment that repels sweat, light rain, and humidity. While the M165 isn’t submersible, it handles the moisture exposure that comes with daily outdoor use. This coating also protects against corrosion in high-humidity climates.

Common questions about the Plantronics M165
You’ll get up to seven hours of continuous talk time or eleven days of standby on a full charge. The headset charges completely in ninety minutes using the included micro-USB cable. DeepSleep mode extends standby to six months if the headset sits unused, so it’s always ready when you need it.
Yes, multipoint technology lets you pair the M165 with two Bluetooth devices simultaneously. You can stay connected to both your work phone and personal phone, and the headset will automatically route incoming calls from either device. Voice prompts let you switch between active calls without touching your phone.
The M165 features a P2i nano-coating on internal components that resists moisture from sweat, light rain, and humidity. While it’s not designed for submersion or heavy rain exposure, the coating protects against the moisture you’d encounter during normal daily use, including outdoor activities and humid environments.
The headset maintains a stable Bluetooth connection up to ten meters from your paired device in open space. Actual range depends on obstacles like walls and interference from other wireless devices. Most users find the range more than sufficient for moving around an office or home while staying connected.
We include small, medium, and large gel tips in the box so you can test each size. The medium tip fits most users, but you’ll know you have the right size when the headset sits securely without pressure or discomfort. The curved earbud should rest naturally in your outer ear rather than pushing deep into the ear canal.
The headset supports voice commands on compatible smartphones. Press and hold the call button to activate your phone’s native voice assistant — Siri on iOS devices or Google Assistant on Android. You can make calls, send messages, and control music playback through voice commands while the headset is connected.
The headset announces remaining battery level through a voice alert when you power it on. You’ll also hear a low-battery warning when charge drops below ten percent, giving you about thirty minutes to finish your call or find a charger. The LED indicator flashes red when battery is critically low.
