What is known is that the headset is a head-mounted stereo model with a 40mm speaker and Bluetooth 4.0+EDR. It also has a 3.5mm stereo audio interface.

The headset is described as head-mounted and stereo, which indicates an over-ear or on-ear style rather than an in-ear design. No further dimensions such as headband length or earcup size are provided, so the practical fit is best assessed from the head-mounted format and the 40mm speaker specification.\u003c\/p\u003e\n\u003ch2\u003eUses and Placement\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"B5 wireless Bluetooth 4.0 headset with 40mm stereo speakers, 3.5mm audio interface, available in black, silver, and red\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/8937\/2025-11-24\/original-image\/1873870880889.webp\"\u003e\u003c\/div\u003e\n\u003cp\u003eThis headset is intended for music and for situations where a head-mounted stereo set is useful.
