Open-Ear Clip Headphones
The No Sew M97 uses a C-shaped hook that rests outside the ear canal, keeping the wearer aware of traffic and conversation. Bluetooth 6.0 provides a stable link up to 10 metres. The 12 mm dynamic drivers deliver clear mids and highs with a natural soundstage rather than sealed bass. Weighing only 4 grams, they suit runners, cyclists and gym users who need all-day comfort without isolation.
50-Hour Case and Quick Charge
A compact charging case extends total listening time to 50 hours from a single 6-hour bud charge. A 10-minute top-up adds two extra hours when time is short. Touch controls handle playback, calls and voice assistants without reaching for a phone. IPX5 rating protects the buds against sweat and rain during outdoor sessions.
Simple Pairing and Common Fixes
Opening the case initiates pairing; the buds reconnect automatically afterwards. If audio drops or only one side plays, place both buds in the case, close the lid, then reopen to force a re-sync. Persistent single-side silence usually means the buds lost mutual sync — repeat the case reset or hold the touch area to re-pair manually.

Questions about this item
Will the lithium-polymer battery in the charging case need replacing after a certain number of cycles?
The case provides 50 hours total playtime with a 10-minute quick charge adding 2 hours; lithium-polymer cells typically retain most capacity for several hundred cycles.
Does the 80 ohm input impedance limit volume when paired with a phone over Bluetooth 6.0?
The 80 ohm rating is a driver specification; the built-in amplifier drives the 12 mm dynamic units to ample loudness for outdoor use.
How warm do the clip-on earbuds get during a full 6-hour session?
At only 4 grams each, the open-ear design dissipates heat naturally and stays comfortable for the entire 6-hour continuous playtime.
