This is a 3 month supply. Although there is a guarantee of 6 months to get them. There are those who bought them more than 3 times. It’s not a pity to give 200-300 for them, they are still at that price. Philips makes equipment, to put it mildly, not very well in some segments. Pros: Isolate outside noise. The sound in them is on a deaf Chinese. The amp didn't fix it. For your FBontakte empetris will do. They say that ear plugs spoil the hearing to the point of not being recognized, but outside the outside world is not audible. Various cheerful colors are always available. By design, they turned out to be strong and work out their time. The cheapest. Completely Has cons: They didn't fit in my ears. Sound pressure is low quality. They look like something bad and I felt bad from them after 15 minutes. The price is high for this quality.
