Wireless earbuds with Bluetooth 5.3

The No Sew i25 are true wireless in-ear headphones built around Bluetooth 5.3 and a 14.2 mm composite diaphragm driver. They deliver stereo sound across a 20 Hz to 20 kHz range using AAC and SBC codecs. An ENC microphone handles calls, while IPX7 waterproofing and ear hooks keep them secure during workouts. A 400 mAh charging case extends total listening time to 48 hours.

Who these suit and who should look elsewhere

Commuters, gym-goers and office workers who want stable, low-latency audio with quick top-ups will find the 10-minute charge for two hours playback practical. The hook design and IPX7 rating suit sweaty sessions and outdoor rain. Buyers who need active noise cancellation, wireless charging, multipoint pairing or a transparency mode should consider other models because those features are not included.

Battery capacity and real-world headroom

Each earbud provides six to eight hours of continuous play on a single charge, and the case stores enough energy for several full recharges to reach the 48-hour total. A ten-minute top-up restores roughly two hours of listening, useful for short breaks. Heavy users who regularly exceed eight hours between case recharges or who want weeks of standby without plugging in will find the capacity limiting.

Questions about this item

What Bluetooth version must my phone or laptop support to pair with the i25 earbuds?

The i25 earbuds use Bluetooth 5.3 and support HSP, HFP, A2DP and AVRCP profiles, so any device with Bluetooth 5.3 or earlier that implements those profiles will pair and stream audio.

Will the i25 earbuds stay connected if I keep using a Bluetooth 5.2 laptop?

Yes, Bluetooth 5.3 is backward compatible with Bluetooth 5.2, so the i25 earbuds will connect and work normally, although you will not see the 150 % speed increase or 50 % stability improvement quoted for 5.3-to-5.3 links.

How can I confirm the i25 earbuds are charging and holding power after I put them in the case?

The charging case has an LED percentage display that shows the case battery from 1 % to 100 %; when the earbuds are seated correctly the indicator will rise, confirming they are charging toward the 8-hour single-charge playtime.
