Open-Ear Single Earbud

The No Sew F22 is a single open-ear Bluetooth 5.3 headphone that rests outside the ear canal. Weighing 0.64 ounces, it uses bone conduction to deliver audio while leaving the ear completely uncovered. A flexible earhook and skin-friendly ABS construction keep it stable during movement. IPX5 rating protects against sweat and rain.

Suited For Situational Awareness

Runners, cyclists and warehouse workers who must hear traffic, alarms or colleagues will benefit from the open design. Dual microphones with ENC algorithm aim to keep calls clear in noisy settings. Users who want stereo music, deep bass isolation or a pair of buds for immersive listening should look at a different form factor.

15-Hour Battery Decides Fit

Rated playtime is 15 hours at 50 percent volume, with a 1-hour USB-C recharge and 75 mAh cell. If a full work shift or marathon training session exceeds that window, the single bud will need a mid-day top-up. The 10-metre Bluetooth 5.3 range covers phone-in-pocket use but not whole-room roaming.

Questions about this item

What comes in the box and do I need a separate charger?

The package includes the single open-ear earbud with adjustable earhook and a USB-C charging cable; a USB power adapter is not included so use any standard 5 V charger or powered port.

Should I expect 15 hours or 30 hours of playtime from the F22?

The specification lists about 15 hours at 50 % volume; the 30-hour figure appears in promotional text but the rated battery capacity is 75 mAh with a one-hour charge time.

How far can I move from my phone while using Bluetooth 5.3?

The rated transmission distance is 10 metres (33 feet) in open space; walls or interference will reduce the practical range.
