Sony WH-CH520 Wireless Bluetooth Headphones On Ear with Mic, Up to 50Hrs Battery, Quick Charge, DSEE Upscale, Multipoint Connectivity, Voice Assistant, Customized EQ-Blue

So if you're considering to buy this pair of headphones or have already brought it and need a little tweak to the sound to up the excitement, give this review a read. I know it's somewhat lengthy :( but if you've already bought this pair, skip to the last part, that is, bonus.Sound quality:-Pretty good. As you might know, Sony is Sony when it comes to sound. The audio is clear and has that calm, balanced profile that I prefer to the bass oriented profiles of BoAt and JBL. If you are a basshead, I don't think these headphones will be your go to. But if you've been using bass heavy headphones, you will feel and instant change in audio quality and the overall beauty of music once you switch to a Sony device. Keep in mind that I'm not a professional audiophile or something. I love listening to quality music and watching movies and these headphones are perfect. I use Apple music and the sound is bliss, idk about Spotify though but I think it will fare equally well. I like bass and these headphones do provide bass, just that they are not overkill and distort the entire sound looking for it. These feel more premium in the sound department. However some people might feel a lack of excitement in their sound out of the box. Worry not, I've added an EQ tweak to fix your problem at the end of this review.Specs:-30mm drivers. So not as loud as the 40mm ones BoAt and JBL offer in this price range. But I've felt (personally) the audio quality to be better. Bluetooth 5.2 which is solid. Multipoint connection makes sure that this will not be outdated soon. They've been released in 2023 and will remain in contention for atleast a couple of years. Multipoint has to be turned on in headphones app and I use it to connect the headphones to my Macbook to watch movies and to my android phone, which might be on charging or in another room, to attend calls. The switching is seamless and works well. They don't have touch controls though, so it will take a couple of tries to learn to get the buttons right, especially in a dark room. They have DSEE which is basically a feature to enhance low quality/ compressed audios downloaded from internet. It has to be turned on in the app and is not needed for Spotify or Apple music as they are already best quality music and DSEE takes up additional battery charge. Battery is solid. They were 70% out of the box and after 20 hr playback still had 50% left. So I guess they'll last for atleast 50 hrs like they claim on the box. I don't like charging my devices all the time and I use them for max 5 hrs a day for which they will last close to 2 weeks which is good. No ANC though, it's not a problem for me but if it is for you, don't buy. Mic is good, I've attended calls in the midst of traffic and they were pretty fine.Comfort:-I've tried many midrange headphones and these are some of the best in terms of comfort too. Soft earcups that sit compact on my ear. However if they are not positioned properly, they might exert pressure. But on proper positioning, they will give 2 to 2.5 hours playback without any discomfort. After that you will have to take a break. I don't have big ears btw. They are lightweight and have an adjustable headband with cushion. So as far as on ear headphones are concerned, these are comfortable.Build:-Plastic but feels durable. Not creaking. The earcups are the types which forms wrinkles, they look durable but I don't know if they will pinch unless I use it for atleast 6 months. Anyway these have replacement earcups available online and in Sony service centers. I have one near my house. I don't think they are sweat resistant so don't use it for workouts. For jogging they will stay in place once positioned compactly, but for running they will slip off ear.Drawbacks:-Lack of aux cable. Once you are out of charge, that's that. It says they support fast charging on box, but I haven't tried that so idk. Normally takes 2 hours atleast to charge from 20 to 100. Another drawback is portability. They are not foldable and even though the plastic feels durable, I'd suggest you don't bump them much. While travelling either buy a case or carry them around in the box they come with (don't worry about looking cheap, the box doesn't have anything like specs or other bs written on it. Only thing written is Sony. It's inside the white cover that mentions specs).Conclusion:-They offer value for money if you ask me. The sound is premium for a budget segment and not too bass oriented. The headphone app means it will get firmware updates and has some listening modes that actually work, it is not a gimmick. They look and feel premium too. And unlike Anker or ATH, they have service centers all over so if any issue pops up, that's an added boost too. The don't have an in box warranty card but worry not, the moment you connect your device to the headphones app they are registered. Keep the Amazon invoice with you, in the box or download it in pdf form from your orders section.Bonus:-If the headphones lack excitement to you out of the box, the headphones app offer some preset EQ. But I will share this tweak I found from reddit. They worked for me so if you don't know how to configure the EQ on your own, try this;Select manual on EQ in Sony headphones app.Put 400 to 2.Put 1k to 4.Put 2.5k to 7.Put 6.3k to 7.Put 16k to 5.Put clear bass to 2.Try out this tweak and see if it works for you. This works on some higher end Sony models too. Enjoy your headphones!!!

Nice Noise Cancellation, it's not active but the passive ones even block the loudest of noises for example background noise of crowd.The battery is huge; I am not an all-time listener, and it takes me a week to drop the battery from 100 to 90. Even now after being with me for 20 days, it is still running on its first charge (still 96%).Charging speed is okay and justified due to battery backup.Mic quality is good, could have been better.The vocals are beautifully audible and crisp; I could clearly differentiate between voice quality of these with my previous earbuds.Sweet color and it don't go dirty or pale.App does wonderful changes through equalizer, UI feels old-ish nonetheless acceptable.The only downside is its bass; it is not up to the competition and doesn't feel immersive.TL; DR: every functionality good, bass okay.

I am writing this rewies after using it for 1.5 years but still its like new one , best durability ,best build quality , best headphones for better sound quality. 10 out of 10.

Love it. Although is doesn’t have noise cancellation, but it does have Sound isolation.So the person next you cannot hear what you’re listening to plus you don’t hear outside noise much.

Got the pink one, was more of a lavender color but whateverLoved the product anywaysSound quality is mid tho

Looks like you have delivered an old piece. It does not look like new one

This is number one product, it is pure gold, heard? pure gold…

I have to adapt to this on ear headphones. Didnt realize it would be sweating like this. Sound was amazing after setting EQ.
