Highly recommended.Good bass and fits well.Comes with a l 115 Centimetres long cord which extends to a friendly Ear designed shape probably to prevent from getting entangled with movements.Fioo Mp3 players are expensive compared to Eight years ago so I tested these on a Sony NW-A55 Series and Samsung phones.It performed well on all devices but i think it depends on the original source.I wasn't expecting a miracle at this price but the FIOO JD 10 Earphones truly impressed me with its sleek design and sound quality.Tried and tested.Thank you Seller.
