No problem with actual product or service/delivery. That was great. I stupidly followed the Amazon "other customers purchased together" thinking it was compatable with the phone I was purchasing. This is not the case. Read the small print with the phone you are purchasing. So I cannot really comment on product as cannot use. However, no problems with supplier.
I'm using this with a Gigaset IP phone (mainly so the kid can talk to his friends while they play Minecraft). The sound quality is OK, in fact rather good. The mic is also nice and sensitive and rejects noise fairly well. It is rather fragile and feels like if might break with some rough usage. Still, you get what you pay for, and this isn't an expensive item.
The product arrived earlier than expected considering Christmas time with which I am really pleased but jumper could have been better. The sleeves look out of shape. I ordered s/m which was itself big considering I am size 10/12 and could not order anything smaller than s/m as it wasn't an option.
i'm afraid i experienced lowsound levls on this headset, i did wonder if it was the socket the headphone plugged into however when tried on another phone it was the same. i ordered a new headset (BT Accord 10 Telephone Headset) that works just fine.
Most uncomfortable headset ive ever worn, and ive had a few, Its ok(isk) if u dont have to extend it, but once adjusted the SHARP slider where the extension comes out off digs into your head, returned, end of problem.
