This is it


I wish to buy this excellent technology





Excellent experience - product tracked and as per advertisement



It just arrived on time and with great quality. Best wireless headphones under 100 dollars. I highly recommend it.

A really nice pair of headphones


These headphones are a wonderfully comfortable pair that can be worn for hours on end without any fatigue or problems from such a long wearing period. The packaging is first class, the instructions quite sparse but able to be followed easily. The controls are easy to find and use and it works a treat with my Fiio M6 DAP. The volume from the wireless connection is quite a bit lower than the wired connection but the earpads being soft and plush will help to isolate the external noise quite a bit. The comfort of the earpads is excellent, for my ears they do not cover completely and there will be a little bit of leakage, not too big a problem. The audio quality is to my ears quite neutral and does not colour the sound that you are listening to. Overall I am very pleased with these headphones and can strongly recommend them if the HD 4.50 BT are a little too expensive. These do offer exceptional value for money and is a great way to get away from the wired connection. Only need to be used if the batteries die, the life of the battery will improve with each charge and I am confident they will live up to their quoted time. Highly recommend these headphones they are well built and do not leave you in any doubt that they will last for years.

Excellent product and service
