I've had mine for two months and bought them for SEK 1290 on Netonnet. Never had true wireless before.
I use them daily for practically everything - music, videos, phone calls - at work, at the gym and at leisure.
The build quality feels very solid and robust. Have dropped them a few times without a scratch, and I do not worry about them breaking. Sweat / dust warranty of two years. Stylish design (blue / copper). They are slightly thick and stick out a bit from their ears, should anyone with excessive vanity read this.
Comfort and fit depend quite a lot from ear to ear, but it comes with two extra pillow pairs in other sizes that at least make them suitable for most people. I ride on the biggest ones and they sit like cast in the ear. They have never trembled with vigorous movements (being a gymnast and throwing their heads around in all possible directions).
The button presses often cause you to mash them in the ear canal, which is unpleasant, but you react to that most at the beginning. You must take a little pain. If they get too deep, however, they can sometimes block the sound for some strange reason - but just need to sneak a little on them and they adjust.
The sound quality is good. Not exceptional in any way, sounds good simply. A big plus for a 5-band equalizer in the app that gives you the ability to adjust bass / mid / treble as you like. The Hearthrough function is brilliant, sounds from the environment are captured by the mic so you can answer "hello", "thank goodness" and "you can throw the receipt" to the cashier without removing the headphones.
Other technical eyebrow raisers for me were that I typically never have to think about turning them on or off. Happens automatically. You can also have only one headphone (the right one, the master) if you want it for some reason. The app also has a GPS feature so you can see where you last had them if you happen to fumble them.
Battery life is cruel. They held a full 5-hour bus ride a while ago, with about 10% left. Also nice that you can see the battery percentage in the app, seems to be pretty reliable.
In everyday life they hold even better because they often take them off and on, and then it is quite natural to put them in the case (2 whole extra charges) that refuel them again.
The case is small and handy. Neat, sturdy. Has a hinge indicating the battery status of the headphones and one for the battery of the case. Nothing to complain about. USB-C would have been nice but how irony spiky must be. Here's how much extra work it means: Disconnect the USB cable from the charger you have for your mobile. Insert the microusb cable. Two hand movements. Get it together.
4.5 / 5 rounded up means 5/5, hurray!
