Sony WI-C400 review

  (Rating Hidden)

With a claimed 20 hours of battery life, the Sony WI-C400 headphones blow most wireless in-ear pairs out of the water. If they manage to sound good too they could persuade many to abandon their bulky wireless over-ear pairs. Read our full review to...

The Sony WI-C400 are average-at-best wireless in-ears with an easy-to-use control scheme and a long battery life. They're stable enough for sports use and have a decently comfortable fit, but they have a treble-heavy sound that may be a bit too...

Over priced Sony's, my first pair of Sony's for a long time and will be the last. Sound quality average, battery life was not what it states, more like 10hrs and not the 20. Neck band is a hard plastic and gets in the way when doing the weight bars!...

No worth the money


To start with the earphones were really good but after about 5 hours use they started to skip and the sound quality rustled every so often. The buttons and neck rest part feel very plastic and the quality is just not there.
