Wireless earbuds with 48-hour case

The No Sew I63 are true-wireless in-ear headphones that use Bluetooth 5.4 for audio and calls. A 14.2 mm dynamic driver in each bud delivers stereo sound with 32-ohm impedance. The charging case extends total listening time to 48 hours and recharges in 1.5 hours.

Commuters and office workers needing long battery

Buyers who want extended playtime between charges and clear voice pickup from four ENC microphones will appreciate the 8-hour bud runtime and 15-metre wireless range. Listeners who require wired connectivity, aptX or LDAC codec support, or active noise cancellation should consider other models.

14.2 mm driver size

The 14.2 mm dynamic driver is the core component that determines bass depth, mid-range clarity and overall loudness. If your priority is maximum low-end impact or audiophile-grade detail retrieval, the driver diameter is the single figure to compare against alternatives.

Questions about this item

How can I confirm the Bluetooth 5.4 link is active after pairing?

The earbuds automatically reconnect to the last device once paired; a stable connection within 15 metres and audio that stays in sync with video show the link is working.

What comes in the box and what must I buy separately?

The package includes the I63 earbuds, a portable charging case and three sizes of soft eartips (S/M/L); a USB-C charging cable and a power adapter are not included.

Which capacity version should I choose for the longest playtime?

The I63 model provides up to 48 hours total playtime with the charging case and 8 hours on a single earbud charge, so this version gives the maximum listening time available.
