This is my first Bluetooth headphone, never been fan of Bluetooth because of poor audio quality. When Sony released ldac codec i was really happy and was waiting for xperia but they decided to close their mobile division. After that was waiting for pixel 4 but google’s mobile division has bunch of idiots.
Finally bought iPhone which has crappy audio quality but I suggested one of my senior xm3s and to my surprise they sounded really well on iPhone too. After lockdown i was really frustrated with the news channel that my parents watches. Waiting for xm4 can’t be more painful.
Now coming to review
ANC: i felt no difference compared to xm3, they block the rumble of fans, coolers and pump set but are unable to block the voice of people talking(irritating voice of arnab goswami). They didn’t even changed xm4’s pressure inside the cans after anc is enabled. I still get the same headaches.
Audio quality: not going to write like pretentious audiophile. These headphone are quite versatile if you are bass head then sony has it covered for you (which most of the people like here), bass was way overpowering for me on full setting but i don’t like bass at all. I mostly listen to linkin park, so i set base level at -4 and equaliser on bright preset. This is by far the best audio product i have ever used.
Audio quality wise here is my ranking.
SM es 18<Creative ep830<SM e10s<Fiio f9 pro<one more triple driver<xm3<xm4.
Battery life: I was doing burn in procedure of these headphones, so i kept headphones at max possible volume, so you may get better battery life. I got 18 hr of battery life with anc on. After unboxing battery went down from 100 to 60 in a 10 min and i was afraid that i got faulty unit but thank god a full charge fixed it.
Comfort:Ear cups are bigger than xm3s and hence more comfortable too. After walking with them for half an hour on roof my ear got all sweaty.
Multipoint connection: Works flawlessly, although switching music from one device to another is bit erratic.
Audio lag: I also connected it to airtel xtream box and watched a complete episode of boys with no lag at all.
Speak to talk: still prefer the old put you hand on right ear cup.
Pause when headphone taken off: work 8 out of 10 times.
360 deg reality audio: sony has give 3 months of free subscription of nugs.net but difference was not deal breaker.
Accessories: you get 3.5 mm male cable from both sides, thank you sony for that. Charging cable is really short i mean really. You can use the provide cable just with power bank or laptop. You also get airplane adapter and carry bag too.
Sorry forgot about mic
Mic: It is better than my iPhone 11 pro, my friend used to complain a lot about low volume from my side but with xm4 they had no problem talking to me.
