The device does not work with the Nokia E52, although this is mentioned in the product description. Unfortunately, the operating element in the headset is not working. I then sent the unit about 2-5 days after receipt back to the seller - Withdrawal! - And even pay for the return postage. After that I was 4 weeks holiday and find on my return a packet of TB-Mobile with the delivery note and the headphones! Verwunder that my cancellation was not accepted, I make the pack on and it says Quote: "Returns Please connect the headphones to first and then restart the players!." As the seller would sell me for a fool. Thus, I am on the seller Amazon reported again, but no response. Well nachboren, for 6.50 more, then I must also be stupid, but so you can cut down buyers also have the ear!
