The Sony MDR-ZX770BN are great-looking, comfortable headphones. The lightweight, well-padded ear cups fully encompass the ear and provide efficient button layout and functionality. The headband does not apply too much pressure on the head and the ear cups swivel. Unfortunately, the swivel mechanism feels loose and susceptible to breaking and the build quality of these headphones is a little weak and flimsy.
The Sony MDR-ZX770BN are well-designed headphones that look quite stylish. The two-tone gray and dark gray color scheme and the silver accents on the frame and ear cups are visually appealing. The back of the earcups have a matte, sandstone finish with subtle metallic Sony branding that works with the overall aesthetic.
The Sony ZX770BN headphones are quite comfortable when on the head. The lightweight, softly padded ear cups and headband do not exert too much pressure on the head. The ear cups successfully encompass the ears and swivel, providing a little more comfort regardless of exact placement on the head. The only issues are the lack of padding on the headband and the flimsiness of the swiveling ear cups, which causes some instability when on the head.
Button layout and functionality is simple and efficient. The well-designed buttons are located on the bottom of the ear cups. These headphones provide volume, call-music and skip controls, as well as the power and noise cancelling enabling buttons layed out across the two ear cups. They take a little time to get used to but once you are accustomed they are efficient and the tactile feedback is great.

The Sony MDRZX770BN have large earcups that lay flat to take less space making these headphones somewhat portable. Unfortunately, they don't fold into a more compact format and will occupy a decent amount of space in a backpack. They won't comfortably fit in a handbag and are far too big to fit in a pocket, even larger jacket pockets.
Build quality is decent but feels flimsy. The metal frame of the Sony MDR-ZX770BN is sturdy and flexible enough to handle a decent amount of stress. The plastic used for the build is not the most high-end but is sufficiently dense to not crack after a few drops. Unfortunately, the swivel hinge is loose, flimsy and susceptible to breaking.
The Sony MDR-ZX770BN are moderately stable. However, they're not sports headphones, and they will slip off your ears if used while running or doing high-intensity exercises in the gym. On the upside, they have a wireless design and won't be yanked off your head because the audio cable got hooked on something.
The Sony MDR-ZX770BN are a decent sounding pair of closed-back over-ear headphones. They have an excellent bass, a decent mid-range and a good treble. However, their mid-range is noticeably recessed and their treble is on the sibilant side. Additionally, their performance could vary considerably from person to person, and like most closed-back headphones, don't have a good soundstage.
The Sony ZX770BN's active noise cancelling is not that good. The ear cups provide some passive isolation thanks to the decent seal but, unfortunately, the active cancellation does not efficiently cancel out ambient noise. This means on a busy city commute or on an international flight, noise will seep into the ear cups and distract you from your listening experience. On the upside, they don't leak too much sound.
Sub-par isolation. The passive isolation provided by the earcups is decent, but not good enough to make up for the poor active isolation. The active noise cancellation works very narrowly in the bass range, being most effective only around 40Hz. In the mid-range they don't do much at around 200Hz, but reach a decent -20dB at 600Hz. In the treble range, these headphones seem to perform slightly worse with ANC On compared to when the ANC is set to Off.
Average performance. The Sony ZX770BN headphones leak a lot across a broad spectrum (900Hz-6KHz). If you listen at very loud volumes, you will be hearable from a couple of feet away.

The Sony MDRZX770BN have a decent battery life that delivers about half a day of continuous playback. They charge a lot faster than the MDRZX550BN but cannot stream audio and continue charging at the same time.

The Sony MDR-ZX770BN have an above-average wireless range that's suitable for indoor and outdoor use. They maintained a stable connection up to 40ft rarely dropping any audio, which makes them a good wireless option for a moderately sized office. They offer NFC which makes them easy to pair with mobile devices. Unfortunately, their Bluetooth version is not the most up-to-date and consumes a bit more battery than Bluetooth 4.0. It also has a bit more latency issues with video playback even if they have the APTX codec to reduce lag.
