I didn't expect them to be so good but it's been 6 months and the batery last long and the sound is amazing. 100% recommended!1.2 cm drivers and they show it twice as big as any other earbuds sold and better fidelity as a resultIf you want loud buds with plenty of bass then these are the ones for you!!!The base and sound that comes out of these things is so good. Buy them you won’t be disappointed. They blow Apple’s IPods out of the water.Bluetooth connection *sometimes* behaves weirdly. I can usually move around the house away from the sound source and the earphones are working just fine, but sometimes they just stop, the're still connected but sound stops, then i have to put them in the case and out again... Sometimes the pause button pauses but won't resume playing. All of this rarely happens but it happens. They're definitely better than my old pair though.Todo bien ,lee las instrucciones, para el precio buena calidad,actualización *** es cierto pierden conexión a cada rato,no me gusta eso.I work in a factory...so it's very noisy...with these Buds compared to others I don't have to have the volume all the way up.....excellent soundsQuality - is great (Extra bass)Battery life - great.Noise cancelation - missingApp - missing to adjust settingsComfort - 7/10what can i say " So far so good, but prefer headphones with noise cancelationWorst sound Quality, and Amazon also not taking return of product, don't buy Renewed product, Very disappointed.well @4700 they are hot ? ,comfort: i can wear them until battery runs outbattery: in cool environment exactly 9+ hours at 40-70% volume. in hot condition 8hours.price: even if you buy them @10k they are lit. if you are lucky then renewed too will be like new (disinfected too)performance: heavy bass, good overall details, some connection drop with my laptop, but with ipad pro 2020 its rock strong ? at my house no matter in which room i am and with my galaxy s9 too.cons: no app support from sony, volume down control is worst, and can't connect to two devices at same timeI received my head phones on 21st August 2020, applied for replacement on 21st August 2020,Left side AirPod is not working at all. Right side has low volume( this might me because I was listening a song on only one AirPod)I personally feel it’s luck while buying such products, they have ensured me they will replace the product on 25th August 2020 so that’s quick.Now let’s c when I get the same other product. My experience or learning don’t put 5000 or plus in a used product.They have replaced it and this one is killer it’s been only two days let’s c what happens in long run
