Single-ear design for discreet use

The No Sew Invisible Earbud is a single in-ear headphone weighing 3 grams and finished in a nude colour. Bluetooth 5.0 provides a stable wireless link up to 10 metres for iOS, Android and Windows devices. The button control handles playback, calls and pairing with one hand. It is built for users who need a barely noticeable earpiece for work or daily wear.

Four-hour runtime with magnetic charging case

The lithium-polymer cell delivers 4 hours of operating time per charge and replenishes in roughly 1 hour via the USB charging case. Magnetic retention keeps the bud secure inside the case during storage. IPX5 resistance protects against splashes and rain during active use. The supplier cautions against using quick-charge adapters and recommends a maintenance charge every 20 days if the unit sits idle.

Check ear fit and charging habits before buying

This model uses a single-ear coupling, so it will not suit buyers who want stereo sound or a pair of buds. The 32-ohm impedance and ~3 K-ohm microphone are standard for mobile devices, but no noise-cancelling function is present. Verify that you can avoid quick-charge adapters and commit to the suggested maintenance routine to preserve battery health.

Questions about this item

Will the earbud stay connected to an older Bluetooth laptop I still use?

Yes, the earbud pairs with any Bluetooth-enabled device including legacy laptops running Windows, macOS or Linux.
