## Customer Reviews

### ⭐⭐⭐⭐⭐ Good purchase.
*by W***R on May 23, 2016*

Very happy with the form, fit, function, performance, and quality. Good bass, and crisp highs and midrange. Was hesitant to buy a refurbished product, but aside from not being in a Sony retail package, they're indistinguishable from new. Not disappointed at all! Came exactly as advertised, packaged well, like new, with USB charging cable. Note: I had previously owned some bluetooth headphones from Monoprice, and I was pretty happy with them, but they quit charging after 1.5 years, and they were kind of bulky and "generic budget looking" so I thought I'd look into alternatives. Have always been happy with most Sony products I've owned so thought I'd give these a shot. I'm very happy with them. They're light and comfortable, over the ear design blocks out ambient noise. I wouldn't say that they're overly loud, as I put the headphone volume to max - 1 and my iPhone volume to max -1 and it's sufficiently loud but not anywhere near uncomfortably loud. Hope this helps.

### ⭐⭐⭐⭐ Great set for the price
*by B***N on May 30, 2016*

Pros: battery life, I charge mine every few days, but have yet to run all the battery down. I use these at work for 4 or so hours a day. Well built for the price. Comfortable. Easy to pair with my phone. Controls on the ear piece work with spotify (next song, previous song, etc )Minor cons: ear pieces are faux? leather which are comfortable, but extended use can lead to sweating. I would prefer webbed breathable fabric like my home pc Logitech G430 headset (never sweat in this headset). Sound quality is acceptable and probably as good as it gets for the price, but is not 5 star worthy. An EQ app might make these much better, but I haven't explored that as it is good enough for me so far.

### ⭐ Loses ability to charge
*by R***N on October 18, 2018*

These headphones were great until they lost their ability to charge. I can no longer use them anymore. I’m not sure if it is my specific pair that are faulty or it is this model but I wouldn’t recommend purchasing.
