S42 Bluetooth 5.3 headset

The No Sew S42 is a pair of true wireless in-ear headphones built for listeners who want active noise cancellation and long total playtime from a compact case. They connect via Bluetooth 5.3 and are compatible with most Bluetooth-enabled phones, tablets and computers. Touch controls handle playback, volume and calls without reaching for a device.

60-hour case capacity and 6-hour buds

Each earbud delivers up to six hours of music or talk time on a single charge, while the charging case extends total playback to 60 hours. A dual LED display shows the remaining charge for both buds and case so you can plan top-ups. The 10-metre operating range covers typical indoor use, but the buds will need a return to the case after roughly six hours of continuous listening.

IPX7 build with USB-C case and three tip sizes

The earbuds carry an IPX7 rating, meaning they resist heavy sweat and rain during workouts or outdoor runs. An ergonomic shape and three included silicone tip sizes (small, medium, large) aim to keep the fit secure for long sessions. The case charges via USB-C and the whole set weighs 0.132 kilograms, making it light enough to carry in a pocket or gym bag.

Questions about this item

Will the S42 earbuds stay connected to my phone if I keep the handset in another room up to 10 metres away?

Bluetooth 5.3 maintains a stable link up to 10 metres, so the earbuds stay paired while you move around the house.

How can I confirm the ANC is actually reducing background noise after I put them in?

Switch the active noise cancellation on and listen for a noticeable drop in ambient sound; the ENC microphone also cuts background noise by up to 90 % during calls.

Which ear-tip sizes are included so I can get a proper seal without buying extras?

Medium tips come pre-fitted, and small plus large pairs are supplied in the box for a secure in-ear fit.
