In my flat, there are interruptions at about 10 m through 2 walls. No problem in an open room.

by the way ... the manufacturer gives other values. firstly to sell the product and secondly under perfect conditions... offices made of glass etc.. everything perfect... under normal conditions, a car consumes 2 litres more fuel per 100 km (provided it is not an e-car) and thus the range of the bluetooth decreases. similarly inversely proportional to the car... smile... how many bluetooth devices do you have? i have observed that when bt connections are established, the headphones briefly stop...

in the bathroom, open rooms, there are beeps or interruptions because of two walls. i find the range pleasant. in large open flats, you can easily have reception up to 20 metres. after that, as with all bluetooth products, it is critical, as someone has already described. you can change the channel, i also had beeps at 5 metres open line, so i changed the channel and charged the headphones. i will also change the toslink cable, as it probably causes the beeps. in any case, a great product. very very comfortable to wear. something of the finest for the ears. the sound is unique. suits me... have fun with it, if you buy it... radu k

Hello, the headphones are connected via Bluetooth and therefore the connection is secure up to 15-20m when there is visual contact. After that, it starts to become critical.
