For those who like to listen to bass, this is manna from heaven. microphone is crap.
3 December 2021 
Excellent headphones, the only thing that was a little confusing was the price, but it is justified. I usually walked around with the headphones on all day, periodically listening to something, and they lasted all day without recharging. These are the first headphones I have that were able to last 1.5 years and are still in service, the buttons with the rubber coating of the headphones themselves were worn out in some places, but this is natural because I carried them SOOOOO much. And it’s also a pleasure to listen to them, although they float in sound during songs, but it’s not critical, in general, if your hearing is not subtle, then it’s cool to listen to, and in the bass they reveal themselves to the fullest.
The sound is superb for listening to music
Excellent battery life

After a year of using the Chinese GO2 TWS headphones, I decided to change to SONY WI-XB400 headphones.

Headphones that play well and play for a long time, just the thing to protect yourself from the world
31 October 2020 
I replaced my Redmi AirDots with these. I'm absolutely satisfied with the earbuds; the cable is long and the weight is light.

Regarding features, I use them with AAC on the Mi9T, and the volume control is dual, with one control on the phone and another on the headphones. This is very convenient for me because the phone's speaker doesn't handle full volume well and distorts YouTube, but you can increase the volume in the headphones.

Features:
There's no protective mesh, but on the other hand, the earphone canal is quite long, and the earpiece opening is small. This might encourage some messy folks to clean their ears...

Some people mention weak magnets, but they can't be very strong as they would affect the nearby speaker with their magnetic field...

The soft-touch plastic, or rather rubber, attracts a small amount of dust, but that's a feature of the material itself, not that it gets very dirty. I'm worried it might wear off over time.

The compensatory holes are located at the bottom, so rain won't flood them, and there's a fine mesh there effectively muffling the sound but allowing air through.

The anatomical shape is quite specific, but it suits me well.

The cable seems thin, but it's actually stronger than those of Fischer.
Sound. There is no feeling that the curve has been shifted towards the bass at the expense of the mids and highs. But these are the upper bass and the lower part of the mids.
Type-C, now both the phone, the watches, and the headphones require a single cable for charging; it's good that this time has finally returned.
Battery life, the claimed 15 hours is quite accurate.
Sound insulation, people around me don't hear my music even at maximum volume. The downside is that I don't hear if someone is calling me (a potential plus).
Long charging time, but it's the price for good playback time. Implementing a full fast charge in headphones is extremely difficult, but 10 minutes for an hour of playtime is already good.
The microphone may be muffled by the collar if your clothing has one, so you might need to hold either the remote by your mouth or the collar for others to hear you. In other situations, it's quite normal, no complaints have been received.
