Sennheiser RS180
Sennheiser RS 180 wireless Hi-Fi headphones, with uncompressed Kleer HF link and a range of 100 metres, for comfortable listening at home.
Description
The RS 180 is a wireless Hi-Fi headphone from Sennheiser, designed to broadcast music without cables thanks to its uncompressed Kleer HF link. It relies on a dedicated transmitter that sends the audio signal to the headphones, offering listening free from any wired connection to the source.
Its Kleer HF link operates without compressing the signal, which preserves the original sound quality across the entire stated range. With a range of 100 metres, the listener can move freely around the rooms of their home without the sound degrading or cutting out, an advantage for active listening rather than sitting in front of a system.
The transmitter paired with the RS 180 is multifunctional and can accommodate up to four headphones simultaneously. This feature allows several people to enjoy the same music source at the same time, each with their own headphones, without needing to duplicate playback devices.
This model is intended for domestic use, for wireless listening in the living room or any other room in the house, solo or with others thanks to the transmitter's multi-headphone compatibility. It suits those seeking freedom of movement without giving up audio quality.

What to check before buying used
The Kleer HF link relies on a proprietary transmitter that must absolutely be present and functional: without it, the headphones receive no signal, so it is worth checking effective pairing before any purchase. The earpad cushions compress and deteriorate over time, affecting comfort and acoustic seal, while the headband and plastic joints may show play or creaking after several years of use. The headphones' battery compartment also warrants close inspection, as contacts can oxidise following prolonged storage.
