Sony Headphones | MDRZX770BNB.CE7 is rated 4.6 out of 5 by 18.
Rated 5 out of 5 by from Perfect. When I first thought of buying headphones I never even considered bluetooth headphones, but I saw these and decided to get them, realising they had an aux lead too of course. I never liked the idea of wireless due to the battery issues etc, but these are actually exceptional quality. Long battery life, quick charging and superb quality. I love the positioning of the controls on the headphones also. Noise cancellation is ridiculously good. Headphones do get uncomfortable after long periods of time but otherwise excellent.

Rated 4 out of 5 by from Great I am really happy with the headphones but would like the build quality to be a bit better and I would love to be able to fold the headphones to take up less space. Apart from that the headphones are fantastic

Rated 3 out of 5 by from Poor Bluetooth connection I brought this a few weeks ago and find the Bluetooth connection to be very poor with my mac mini. Despite the mac located just to the right of me, if I turn my head slightly looking left the connection has a tendency to cut out. If you I flip the headphones around, so the left cup is on my right ear, the problem is solved, but they are not very comfortable that way.

Rated 5 out of 5 by from Good choice for bluetooth headphones. Got them last week. Am fussy about audio quality. They qualify. Sturdy, comfortable, discerning sound, nfc, built to last. Similar to AKG by Harman y50-bt which i consider to top of the range in that category.

Rated 4 out of 5 by from Comfortable and simple Altough I have not used these very much since I received them as a present, I find them very comfortable and excellent sound even with regular setting. They connect flawlessly every time, very happy.

Rated 5 out of 5 by from Great headphones Comfortable even when used for long periods. Controls are well positioned and easy to use. Sound cancelling is quite effective but does shorten battery life quite a bit.

Rated 5 out of 5 by from Great headphones! I wore these headphones for 6 hours straight yesterday, they have a great range (about 5 meters), are extremely comfortable and so far so good on the battery life!

Rated 4 out of 5 by from Versatile headphones Bought for travel noise cancelling great. Can plug in for airplane sound. Little bit heavy on the ears and material in cushion could use better ventilation.
