Bluetooth 5.3 audio adapter for TV and stereo

This compact transmitter receiver adds wireless audio to televisions and home stereos that lack built-in Bluetooth. It serves both roles: send sound from a TV to two pairs of headphones, or stream music from a phone to a wired speaker system. The dual-mode design suits living-room listeners who want private late-night viewing or whole-room playback without running new cables.

Battery life and wireless range

A built-in 500 mAh cell delivers over 10 hours in receiver mode and over 8 hours in transmitter mode, recharging in roughly 2.5 hours from a Micro USB 5 V 0.5 A source. The Class I and II radio operates across the 2.402 GHz to 2.480 GHz band with a claimed line-of-sight reach of 80 metres. Distortion stays at 0.1 percent, so audio remains clean at typical living-room distances.

Codec flexibility and simultaneous connections

In TX mode the unit pairs with two headphones or speakers at once using apt-X LL, apt-X, SBC or FS codecs. In RX mode it holds two phones simultaneously via apt-X LL, apt-X, SBC, AAC or FS. RCA and AUX ports can output together, letting wired and wireless zones play the same source. The adapter prioritises apt-X LL for lowest latency when both ends support it.

Questions about this item

How do I install the eEAR Bluetooth 5.3 Transmitter Receiver using the RCA and AUX connections?

Connect the unit to your TV or stereo via the RCA or I2S AUX interface; both outputs can work simultaneously. Pair headphones or speakers in TX mode, or pair phones in RX mode. Charge via Micro USB 5V/0.5A for about 2.5 hours before first use.

What maintenance or replacement will the eEAR Bluetooth 5.3 Transmitter Receiver need later?

The built-in 500mAh battery is not user-replaceable; expect runtime to gradually drop below the rated 10 hours in RX mode or 8 hours in TX mode after many charge cycles. Recharge using the Micro USB port at about 350mA when depleted.

What is the range limit that appears first under sustained use of the eEAR Bluetooth 5.3 Transmitter Receiver?

The stated line-of-sight range is 80 metres, but walls, interference in the 2.402–2.480GHz band, or battery drain during long sessions will reduce the practical distance well before the 0.1% distortion threshold becomes audible.
