Before choosing
When it may fit
They may suit study, work or travel if you prefer cushions around your ears and buttons for playback control. Multipoint maintains two device connections; check the conditions for switching music and calls. Ambient Sound Mode brings in external sound when needed. Headband and cup fit affect isolation; the stated weight does not guarantee comfort for everyone.
Limits
Sony specifies a maximum of 35 hours of music with cancellation on and 50 hours with it off; actual battery life depends on features, volume and operating conditions. Cancellation reduces noise but does not remove every sound or guarantee that surrounding warnings are audible. They are not waterproof. Documented codecs are SBC and AAC; LDAC is not advertised for this model. DSEE processes compressed music without establishing exact restoration of the original. We have not physically tested sound, battery life, calls or comfort.
Check before buying
Confirm black WH-CH720N, an approximately 1.2 m audio cable and an approximately 20 cm USB-A to USB-C cable. Sony does not list a case in the reviewed package. Check the power adapter you need, your device connections and current Sony app requirements for customization. The guide documents USB-C charging and a 3.5 mm audio cable input. Avoid charging wet components. Review seller, condition, regional warranty, price, delivery and returns on Amazon; another color’s price does not establish the black variant’s price.
