Up to 2.5k is what you need. More expensive really does not make sense to take. And guys, freedom from wires is something. I will never switch to wired headphones again. Got pros: Value for money is the only way to describe them. Took for 1800 from China. For such a price, just a gift! So: The sound is on a solid 3ku, well, it’s not fire at all, yes, but if you listen to something like rock, everything will be a mess. Assembly - everything seems to be monolithic, but after a month at the right ear, when put on, the earphone cover (which is touch-sensitive) will be fastened together. And also many complain that I will confirm - the case cover is loosened a little to the left / right. Charge - real numbers. At full volume, 3.5 hours of music. And still the charge remained less than half. I read that the guys have about 4 hours of battery life. They fit perfectly in the ear, training in them is comfortable! With its cons: Again, the sound, to be picky about it, really everything depends on the price.
