Bluetooth-koptelefoon Usams BHUSD02

The Usams BHUSD02 Bluetooth Headphones combine Bluetooth 5.0 connectivity with a compact, lightweight design to deliver reliable wireless audio for everyday use. Constructed from ABS material and finished in blue, these headphones offer Hi‑Fi sound reproduction across a 20 Hz–20 kHz frequency range and include an integrated microphone for hands‑free calls. The set comprises two 4 g earbuds with 13 mm drivers, a charging case with a 300 mAh battery and touch controls for playback and call management. Typical playtime on a single earbud charge is 3–4 hours, with additional charges available from the case for extended daily use.

Advantages

Bluetooth 5.0 ensures more stable wireless transmission and reduced latency compared with earlier versions. The 13 mm speaker drivers and sensitivity of approximately 103 dB provide clear audio reproduction across the audible spectrum. Lightweight earbuds (4 g each) and ergonomic construction support extended wear without significant fatigue. Fast charging for both earbuds and case minimizes downtime, while a stand‑by time of about 40 hours preserves battery when not in active use. Compatibility with Android and Apple devices with Bluetooth makes the headphones easy to pair with most smartphones and tablets.

Suitable for

• Hands‑free phone calls and voice calls on smartphones
• Listening to music, podcasts and audiobooks during commute or travel
• Everyday use at work, home or outdoors where compact wireless audio is needed
• Short workouts and light exercise where lightweight earbuds are preferred
