Instructions for using are poor as never had wireless heaphones before. Had problem syncing with ipad Air2 but otherwise good after trying various ways to use.

This set of headphones were actually better and cost less than the other MDR headphones I bought from Sony in the past. The reasons are as follows; You can hear the voice automation to let you know they are turned on via the power button whereas the more expensive MDR's didn't, they just beeped. Also it notifies you through voice automation when it connects to the Bluetooth and the other MDR's didn't even have a function for it. They also have better depth of bass and sound amplification. They noise cancel better and they have easier button actions to adjust volume and call changes. The best part about it all is that I have a Sony Z3, a Sony Smartwatch 3 and these MDR headphones and they all function in sync with each other. I'm able to alternate volume and app access through my watch if my phone is within 100 yards of Bluetooth coverage for all 3 devices and the headphones have a prolonged battery life, which means despite the fact I have a mobile charger port device with USB on me, which fits in my pocket, I never need to worry about charging all 3 at the same time. All of them will work off a standard USB Android charger and this makes it easier for commutes to work, exercises at the gym or on the go and my downtime at home. I would only comment on these headphones, but Sony have done an excellent job in making it seamless for their users to incorporate devices to immerse their customers into an easy life with their products. Good job Sony.

Those over the ears headphones are very good. FEATURES: - They are made of steel and leather (ear cushions and head rest), but seem a little heavy. - When they're on, a discreet blinking blue led lets you know that. - A pleasant female voice announce you when: power on/off, Bluetooth connected/disconnected, power level (when On, pressing shortly on Power button you will hear the voice telling how much battery you have left - Power Level Hi/Medium/Low). - Battery last... a lot! I have tested them for 2 sessions of 13 hours each with one charge and after that the voice told me Power Level Medium. I've charged them and, after 3 sessions of about 8.5 hours each, I still had Power Level Hi in one charge. I never got to Low, so I don't know how much it takes from Low to totally discharged. But I think 30 hours advertised are real. - Volume button is easy to use, with a little "dot" that sticks out and you can feel with your finger. - Next to it is the Play/Pause-Next/Previous button. Easy and intuitive to use. "Slide" it up for next song, down for Previous, push it for Play/Pause/Answer/Close calls. SOUND: - They have 30mm speakers, so they don't fully cover the ears (unlike the 40mm). - They have built-in Bass Feature, so EXTRA BASS can NOT be disabled. But, with the right player settings (for me -20Db) you can listen to great sounds on any type of music (from death metal to hip-hop and classical). - With standard settings, Extra Bass can be a little overwhelming, especially that it kinda kills the mediums and high sounds (I am a bass fan, especially for drums loudness, but those ae too much). So, finding the right settings in player equalizer can take some time and testings. - They are NOT Noise Cancelling phones, so don't expect to sound proof yourself when wearing them (I didn't want Noise Cancelling phones because I need to hear the surrounding noises at work). They do cancel most of the noise and, if you listen to moderate - loud music, you won't hear anything around you. - I don't know if, at max level, people near or around you can hear music when you wear them on your head, but keeping them around your neck makes them 2 little speakers that can be very loud. - The quality and clarity of the sound depends on that of the song/video you have and on the player, but the headphones conveys the sounds in the highest quality possible, as Sony should. COMFORT: - They seem a little heavy, especially if you go from in-ears phones. - Ear cups can be adjusted individually in any position (up, down, left, right), so, eventually, you can find the right position to feel comfortable. - They create some discomfort when wearing them for a long time (I wear them for at least 8 hours a day, but I still can't wait to take them down in breaks). The head band presses the speakers onto the ears, making them a little painful to wear for more than a half of hour, also making the ears very hot (nice when it's cold outside). But, with the stainless steel headband, you can widen the headphones a little to meet the desired comfort (I am big headed, so I had to do this to be able to wear them for 8-12 hours at work). For those with "normal" head, I don't think they will be a problem. - The cups feel nice, dressed with soft foam and covered with quality leather. OVERALL: They are hi-quality made, great sound, Extra Bass as the name is, intuitive and easy to use controls on the Right side, fast charging with the micro-usb port on the right side. Not good for running/jogging, as they tend to slide off the head on sudden moves.
