Features and Construction

The core construction combines a closed back buckle, soft sponge, and protein leather ear cushions with a soft durable headband. These materials and fittings are stated in the source text and are relevant to everyday use, storage, and comfort during listening sessions.

Material and Build

The ear cushions use a soft sponge and protein leather, with a leather material inner lining as stated. The headband is described as soft and durable. The closed back buckle forms part of the ear cup structure. These details come directly from the source text and describe the physical build rather than making performance claims beyond what is stated.

Size and Practical Fit

The earphone measures 12.5 x 8.5 x 17.5 cm and weighs 390 grams. The foldable design reduces the footprint for storage and transport, which is useful when space is limited. The over-ear format with protein leather cushions is designed for extended use, and the foldable mechanism makes it easier to pack away after use.

Uses and Placement

This earphone suits wireless listening at home, during travel, or in a workspace where a wired option may also be needed. Bluetooth 5.0 and the 3.5mm stereo plug give two connection routes, and the integrated microphone supports calls.

Event or Professional Use

For calls or online meetings, the integrated speaker and microphone with noise reduction echo support hands-free conversation. Bluetooth 5.0 provides up to 10 metres working range, so the earphone can be used away from the connected device. The 400 mAh battery gives up to 10 hours of talk time, helping cover longer sessions without frequent charging.

Everyday Home Use

At home, the 40mm speaker and 32 impedance support music playback, with 8-12 hours music time from the 400 mAh battery. The foldable design allows the earphone to be stored compactly when not in use. The 3.5mm stereo plug provides a wired alternative when a Bluetooth connection is not preferred.

Benefits and Buying Value

The main practical benefits are foldable storage, dual connection options, and a rechargeable battery with stated music, talk, and standby times. These are directly drawn from the source text and support everyday portability and use.

Reuse and Low Maintenance

The rechargeable 400 mAh lithium-ion battery supports repeated use via the Micro USB charging interface at 5 V / 1A. The protein leather cushions and soft headband can be wiped with a soft dry cloth. The source text does not provide detailed care instructions, so only minimal material-based guidance is given here.
