Nozzles. Included are 3 sizes of ear cushions (rubber endings, those same vacuum "plugs"). With the same success, they could invest one, three is very little. By default, the average size is dressed, the smaller one is just an excuse for picking, spitting, they are significantly smaller in diameter than the earpiece itself, and therefore it simply does not fit into the ear all the way. A larger size is for rare people who probably have a head that is a third larger than mine, or simply those who have been hammering their ear canals with the same products for many years. For one and a half kilorubles, they could throw at least 10 different pairs of rubber bands there, at least instead of their bag. I think it's just bullying. In sum, their vaunted "Noise Isolation" for me is just the effect of "stuffed ears", this can be achieved for free.
The wire. In the specifications on the . Market, it is listed as "asymmetric". That is, the left ear is like an ear, and for the right, the wire is somewhat longer in order to lead it also on the left side around the neck and wrap it around, bring it out to the right. Why they do this at all, I can’t imagine, probably stupid for now, but for some reason so many do it. But I remember 6-7 years ago, in standard ears for Nokia 5700, at least it was done well - the right wire was enough to go under the shirt collar, full length under the collar, and out to the ear from the right end of the collar. Here, the right wire is 25 cm longer than the left one. This is ridiculous, neither fish nor meat. I would be fine with a difference of about 40, or just symmetry.
"Enhanced Bass" is printed on the box in silver letters. I did not hear anything new, despite the fact that on speakers with a simple subwoofer, the sound of the same files is still more interesting. But for the first time in my life I heard other "basses". They occur when the wiring hits the elements of clothing. Any touch of the wire with your finger is also carefully transferred to your ears with wonderful low-frequency measured blows.
