Auscultador Hama 00221847 com fios e sem fios Bluetooth preto

The Hama 00221847 Wired & Wireless Bluetooth Black headphones provide a flexible listening solution for TV and mobile devices. They feature a latency-free 2.4 GHz wireless connection via a USB-A dongle for real-time audio from the TV, while Bluetooth support enables phone calls and music streaming. The closed circumaural design, soft earpads and padded, adjustable headband ensure comfortable long-term wear. A built-in rechargeable battery offers up to 16 hours of use, and the headphones can also be used wired (cable not included).

Advantages

The 2.4 GHz radio link delivers interference-free, low-latency audio for TV viewing, and the plug-and-play USB-A dongle pairs automatically with the headphones. Three sound modes (Voice, Full, Normal) and a direction pad allow easy volume and sound adjustment. The closed acoustic design and passive noise suppression minimise external noise, while soft earpads and a padded, adjustable headband provide extended comfort. Bluetooth adds telephony and music playback options. An automatic power-off saves battery when no signal is detected.

• Watching TV and films without disturbing others
• Listening to music wirelessly from a phone via Bluetooth
• Making hands-free calls with Bluetooth-connected phones

How to use

Insert the supplied USB-A dongle into the TV’s USB port; the headphones will connect automatically via the 2.4 GHz radio link. Use the direction pad to adjust volume and select the desired sound mode. To use Bluetooth, enable pairing on the headphones and pair them with your phone or other Bluetooth device for calls or music playback. If you prefer a wired connection, plug in a suitable audio cable (not included). The headphones switch off automatically if no audio signal is received for approximately three minutes to conserve battery.

Recommendations

For lowest latency when watching TV, use the 2.4 GHz USB-A dongle connection. Charge the headphones fully before first use and monitor battery level during extended sessions; switch to a wired connection if battery is depleted or if your TV does not accept USB audio dongles.
