Wireless audio transmitter/receiver HAMA Link.it duo 3.5 mm, Bluetooth, 10 m range, USB powered, black

HAMA Link.it duo is a compact wireless audio transmitter and receiver that adds Bluetooth connectivity to devices without it. With a 3.5 mm audio interface, optical connectivity capability and USB power, the adapter enables wireless audio streaming from or to TVs, Hi‑Fi systems, projectors, speakers and headphones within a range of up to 10 metres. Supplied cables include 3.5 mm audio, RCA and USB‑A to USB‑C for convenient connection and powering via a USB port or USB mains adapter.

Advantages

The device functions as both a Bluetooth transmitter and receiver, allowing flexible use cases such as sending audio from a TV to headphones or receiving audio from a phone to a stereo system. Auto‑pairing simplifies setup by pairing devices once and reconnecting automatically thereafter. APTX support improves audio quality over Bluetooth, and USB power means no separate battery is required—power can be drawn from a TV USB port or a USB power adapter. Multi‑point capability enables two pairs of headphones or two audio sources to be connected simultaneously.

Suitable for

• Adding Bluetooth to TVs, projectors or Hi‑Fi systems that lack wireless audio
• Connecting Bluetooth headphones or speakers to non‑Bluetooth audio sources
• Sharing audio with two pairs of headphones from a single TV or audio source
• Streaming audio from mobile devices to a stereo system without rewiring

How to use

Connect the HAMA Link.it duo to the audio source or playback device using the supplied 3.5 mm cable, or use the optical connection if available. Plug the USB power cable into a USB port on the TV, projector or a USB power adapter to supply power. Set the adapter to transmitter mode to send audio from the TV to Bluetooth headphones, or set it to receiver mode to accept audio from a phone and play it through a stereo system. Follow the device pairing process once; after the initial pairing, the units will reconnect automatically when Bluetooth is enabled.

Recommendations

For best audio performance, keep a clear line of sight between the adapter and the Bluetooth device and avoid obstacles that can reduce range. Use the optical connection where possible for the lowest interference. If using two audio sources or two headphones simultaneously, verify both connected devices support the required profiles for optimal behaviour.
