Very good sound. But.. they don't sit well in my ears. I got them theoretically for running. But they don't stay in place. Especially the left one. Good noise cancellation. For athletic activity like running, I wouldn't recommend them, although every ear is different. It just hadn't happened to me before.

Relatively balanced for budget Bluetooth handsfree.
- The 2.5 and 6k frequencies are a little overemphasized. I reduced them by 2 notches. I also reduced the 16k by 1 notch. If you look at the headphones' frequency response, with these settings they balance out somewhat. Clear bass -3 so it doesn't overpower the other frequencies and become annoying. Alternatively, if you want a bit more upper mids, just lower 2.5k and 6k by 1 notch.
Honestly, I would have liked the sound to be flatter; I didn't expect Sony to have such a colored sound.

- Monster battery, it doesn't run out easily at all.

- Comfortable and light (with the right eartips).

- I use them with AAC and DSEE on.

- The microphone is bad. For some reason it focuses a lot on noise... really strange.. You can't use it if you have even a little noise around you.. big disappointment..

- There is good passive noise isolation. The transparency mode isn't strong enough, so it's useless as it is.

Very good in terms of volume, fit, battery life, and they are very durable. Additionally, at some point I was on a call, had my phone in the car and was wearing the headphones, I went inside the house, went up a floor and they were still connected and I could hear normally! I've had them for about a year and they've started losing connection with the phone from time to time and the case needs charging much more often, but they are definitely worth it!

Awesome, easy to use, the sound is incredible, the volume is extreme.
Good fit in the ears
I got it for music at the gym and in general.
I haven't tried it on calls yet.

They are very good headphones for their price, I actually bought them twice because I lost the left earbud of the first one. Good battery, good sound, and the sound ambience is good. I love them.

I was urgently looking for headphones for the gym as the ones I had for 25€ for 3 years and was satisfied with broke.

Unfortunately, I was disappointed the moment I put them on, yes I changed the ear pads so they would sit firmly in my ear but the problem is that they don't fit in a way that you forget you're wearing them, instead you feel like they're hanging.

As soon as I wore them at the gym my whole day was ruined since the noise cancelling simply doesn't exist, I was listening to music and at the same time noise from the surroundings.
A chaos in my head and I couldn't concentrate.

I expected at least the basics from Sony.

Great budget buds
They have all the essentials
Excellent sound
Amazing app
Only fown side is that they don’t sit That well in my ear but I don’t think other people are gonna have a problem with it

To be honest, I was a bit disappointed. Their sound is good - for their price - nothing extraordinary. However, the big disappointment is their microphone. It's terrible. Not only does it not isolate the voice, but it also amplifies the ambient sounds, resulting in the person you're talking to struggling to hear you if you're somewhere outside. For calls in quiet environments, it's OK. If you only want them for listening to music and making calls when you're at home, for 40 euros, they are a good choice. If I could return them and spend another ~20 euros to get a better model from Sony or another company, I would definitely do it.

Small, small lightweight case, nice design but in terms of sound it is very basic in a bad way. The app gives you many options to customize it as you want but still it is not enough.

A great choice with very good quality of sound for the price category.
Lots of functions and presents.
They fit well in your ears and they are quite durable.
After all spending a huge amount of money for an everyday carry set of headphones, personally I find it too much.

I got them for 37 euros on Black Friday.

They are very comfortable and they have never fallen out of my ears (except when I slept with them). The sound is very nice and the ambient mode is very useful for me so far both for work and when I'm out on the street. I have connected them so far to 4 devices very quickly and without any problems. The battery, although I haven't calculated how long it lasts, is something that hasn't bothered me at all, so it's at least decent. One thing that helps with this is that they charge so quickly that even after 10 minutes you can definitely use them for a few hours.

Excellent battery life and sound quality. I use them mainly during activities and they stay securely in the ear (I used the largest ear tip). They don't have many features nor the sound quality of AirPods, but they do their job as they should.

Incredible sound, perfect fit, amazing audio, and with the ambient mode, you can hear your surroundings without taking them off. They last for many hours, and I have used more expensive headphones that are unacceptable compared to these. Also, the lack of noise cancelling is not an issue since they nestle so well in the ear that they almost completely cancel out noise in the regular mode. The only downside is that the case's battery runs out relatively quickly and that they are not convenient in a pants pocket due to their shape, but overall, they are worth every last euro

Amazing, they are the most affordable headphones I have and probably the best—in sound—the battery lasts forever—calls—well done Sony!!!
