Description
OPN-672 open-ear listening for workouts and daily wear
The Oraimo OpenCirclet 2 (model OPN-672) sits outside the ear canal so ambient sound remains audible while you listen. Xccessories Lab lists this pair for users who want music, calls, and optional step logging without sealing the ears.
Fit hardware
A built-in ø 0.6 mm memory steel wire works with ultra-soft, skin-friendly silicone so the frame follows your ear shape. The touch-free open-ear layout supports air circulation and hygienic wear compared with in-ear tips.
Drivers and bass processing
An 18×11 mm dynamic driver uses air conduction together with an open-ear bass boost algorithm. The tuning targets deep low end and clear treble for stereo playback in an open format.
Step tracking in the app
An exercise pedometer counts steps in real time and tracks daily activity while audio plays. The counter is disabled until you turn it on inside the oraimo sound app.
Calls and awareness
Dual noise-canceling microphones reduce background noise and echo during voice calls, including while you move. Because the ear stays open, traffic and other environmental cues remain easier to notice during runs, rides, or outdoor sessions.
Weather and sweat
IPX5 waterproofing plus a nano sweat-resistant coating suit training and light rain; the design is aimed at active outdoor use rather than submerged swimming.
Power and port
Expect up to 16 hours of playtime after a full charge. A 10-minute top-up can deliver up to 6 hours of use. USB Type-C charging takes about 1.5 hours.
Wireless features
- Bluetooth V5.4 with roughly 10 m range, low-latency game mode, and stable audio for video and games
- Dual device connection to link two phones or tablets and switch sources; incoming calls get automatic priority
- Google pop-up pairing on nearby handsets (Android 6.0+ with Google Play services) so you skip manual Bluetooth searches
oraimo sound app EQ
Preset curves include Standard, HavyBass™, and Vocal, or adjust bass, mids, and treble manually from the app.
On-ear controls
Touch controls on the headset let you manage playback and calls without reaching for your phone.
