I bought these earphones as a gift. The recipient loves them. I can't speak to the battery life. I purchase was very recent.

This is a great product for anyone starting their own small studio setup! I was cautious at first but im happy with my purchase. :)

It was a great Father’s Day present. It works great for the price and the quality is amazing. Great for the first time riders to get some good quality memories.

Super comfortable and well made. Not great for noise cancellation but otherwise amazing

I would and probably will purchase again. Fantastic lock.

I found myself using these more often (90%) than my Sony WH-XB900. The Sony have more bass and sometimes is too much for me.The Major IV have a nice balanced sound, highs mediums and lows can be clearly heard without exaggeration or overwhelming. I guess if I wanted I could mess with EQ and pump +1db or +2db some low frequency but I am starting to appreciate music in more natural unaltered way. If I am craving for some heavy low frequency I can always switch to WH-XB900 but I haven't had the need for that.They are also lightweight and easy to carry. These are my daily headphones since about 5 months and I have no plans to change them

Very good bit of kit! Used it for the first time over the weekend, over 15 hours using it and probably 4 hours on the phone, couldn’t believe it still had 77% battery left afterwards. Great earpiece.
