🎧 Sony WI-C400 Blue Wireless In-Ear Headphones with Extended 30-Hour Battery Life Review

Good sound quality, ease of use, convenience, compatibility, good Bluetooth wireless range and very, very long battery life. Best deal at $50.

Fits and sounds good, but the battery life is outrageous. I haven't leaked it yet. I used it for 3 hours, forgot to turn it off and left it on all night (no music played) and then used it for a few hours the next day and it still worked! Now I have two of these amazing headphones.

I had a pair of the same brand new black gossamer. I only had them for two weeks. These are way better. The battery life can last up to two to three days before I need to recharge it and I wear it for 8 hours at work. They are light and comfortable. Would definitely buy them again. Get one, you won't be disappointed

I have bought 4-5 of these headphones and all but one are " latest" at the end with One ear doesn't work. Also, they all turn off bluetooth after 5-8 minutes, when I watch the show on my iPad it does it a second time after about 10-12 minutes and then everything is fine. But I want to say I bought 4-5 of these because the sound quality is great until it stops working. Obviously it's not good if only one is working and eventually both quit! Very disappointing! The left ear stops on each of them…

Within a few days of use, the headphones began to jump and/or gurgle underwater. Very disappointing $70 headphones. I will return and replace them. If my replacement is good I will update my review. If it weren't for this shortcoming, I would give the headphones 4 stars. They fit my ears perfectly and I have a hard time finding the right headphones. I like the long battery life and the ease of use of the buttons. It pairs easily with my iPhone, although I think my iPhone needs to be unlocked…
