The Marmitek BoomBoom 55 connects to the audio output of a TV or audio system — digital (Toslink or coaxial) or analogue (3.5 mm jack) — and transmits the sound wirelessly to Bluetooth headphones or receivers. It supports aptX Low Latency technology for up to 40 ms audio delay, removing the noticeable lag between image and sound when watching television. Two Bluetooth devices can be connected simultaneously, so two people can listen at the same time.

The BoomBoom 55 uses Bluetooth 3.0 + EDR and operates up to 10 metres with a Class 2 source, or up to 30 metres with a Class 1 source. It is powered by USB (5 V) and includes a 16-bit DSP DAC with a −95 dB SNR for high-quality audio conversion.
