As bad listening (sudden hearing loss), I used a long year also supplied by Vivanco wireless headphones, connected via the SCART socket on the LED TV, with full satisfaction. As the bow of this unit broke and therefore the two leads were broken, I have even wg. the low price, determined for this product. With him, I am completely satisfied. The tight-fitting handset convey to a distance of more than 10 meters (for me not decisive) a good to very good speech intelligibility. The basses are somewhat thin. Well, I think the 3 adjustable channels, ideal if times the neighbor uses the same wavelength and you can change. According to current findings, I evaluate the battery performance too as well - charged overnight and a listening of about 8 hours at a time is nothing to prevent. What I miss is a mounting bracket which could headset, which is otherwise something disordered in addition to the radio to record.
Another note in the event that the device is connected to the headphone jack of the TV and thus might be issues associated the sound of the TV: In this case, always on the hopefully existing Scart socket via an adapter, the Wireless Headphones Connect device, so that even a mithörender / mitsehender third party can enjoy the adjustable volume of the TV.
