Open-Ear Design & Bluetooth 5.4

These headphones use an open-ear architecture that rests outside the ear canal, eliminating pressure and heat buildup. Bluetooth 5.4 provides a stable wireless link up to 15 meters with fast auto-pairing. The 90 ohm impedance and 98 decibel sensitivity combine with active noise cancellation for clear audio in office or outdoor settings.

Suited for Awareness, Not Isolation

The open fit keeps you aware of traffic, colleagues or announcements while you listen, making it a good match for commuters, office workers and runners. Buyers who need full passive isolation for loud environments or critical studio monitoring should look at closed-back or in-ear alternatives instead.

40-Hour Total Playtime with Fast Top-Up

The buds deliver 8 hours of continuous use per charge, and the case extends total listening to 40 hours. A 10-minute USB-C charge adds roughly 1 hour of runtime, so short breaks keep you going through a work week. Heavy users who exceed 8 hours between case charges will need to plan recharge intervals.

Questions about this item

Will these B15 earbuds pair with my phone that supports Bluetooth 5.4?

Yes, the B15 uses Bluetooth 5.4 so it will connect to any device that also supports that version, giving you a stable link up to 15 metres.

Can I wear the B15 open-ear buds while keeping my over-ear headphones around my neck?

The B15 weighs only 1.2 ounces and uses an open-ear design with flexible silicone hooks, so it sits lightly on the ear and leaves plenty of room for another headband to rest on your neck.

How do I know the B15 is charged and connected after I open the case?

When you open the charging case the earbuds auto-connect to the last paired device, and the case provides up to 40 hours total playtime with a 10-minute top-up adding roughly one hour of listening.
