Ideal for watching the TV or listening to music – with freedom from wires. The Sony MDR-RF811RK headphones bring freedom to music.
Wireless sound – up to 100m
Coming complete with a small base station that connects to your TV or Hi-Fi’s headphone output, these Sony wireless headphones offer a range of up to 100m (under ideal, obstruction free circumstances). Unlike other wireless headphones, there’s no need for a Bluetooth connection, these work entirely independently, making them ideal for all sources.
Long battery life
Boasting a battery life of up to 13 hours, these Sony wireless headphones have enough power for a whole day’s (or more) listening.
Using 40mm neodymium drivers give these Sony headphones a rich, powerful sound. The closed back design keeps outside noise at bay, meaning you hear more subtle detail that would otherwise be drowned out.
There’s little point in being free from cables if headphones are uncomfortable to wear – fortunately, the Sony’s are super-comfy. The self-adjusting headband and deeply cushioned earpads make these a pleasure to wear – even for long periods of time.
Set yourself free, with the Sony MDR-RF811RK wireless headphones.
