Single earbud for mono listening

This green earbud uses Bluetooth 5.1 to deliver wireless stereo sound in a single-ear format. Weighing 3.5 g, it sits on an ear hook with a 108-degree elevation design and internal silicone earplugs for a secure fit. The 75 mAh battery provides approximately 5 hours of talk or listen time and 120 hours of standby.

Suited for calls and awareness.

Professionals who need to stay aware of their surroundings while taking calls will appreciate the mono design and IPX4 waterproof rating. The built-in microphone with -42 dB sensitivity handles voice clearly within a 10-metre range. Buyers who want full stereo separation or a pair of earbuds for immersive music should look at dual-ear alternatives.

Charges in 1.5 hours via 5 V 1 A input

The earbud recharges from any standard USB power source using the supplied cable, reaching full capacity in roughly 1.5 hours. Bluetooth 5.1 with EDR supports A2DP 1.3, HFP 1.6, HSP 1.2, AVRCP 1.6 and D11.3 codecs over the 2.4 GHz band. No charging case is included, so users must plan for a power source during extended outings.

Questions about this item

Does my phone need Bluetooth 5.1 to pair with this earbud?

It pairs with any Bluetooth-enabled phone; Bluetooth 5.1 on the earbud simply enables the 10-metre range and the A2DP 1.3, HFP 1.6, HSP 1.2, AVRCP 1.6 and D11.3 codec set.

Will the ear hook stay secure if I keep using my older over-ear headphones for gym sessions?

The 108-degree elevation ear-hook distributes pressure evenly across the auricle, so it remains stable during intense exercise even if you switch between this 3.5 g single earbud and heavier over-ear models.

How can I confirm the microphone is working correctly after pairing?

Make a call and verify the other party hears you clearly; the microphone sensitivity is rated at -42 dB, and the headset supports HFP 1.6 and HSP 1.2 for voice.
