Overall the product is about the quality you would expect for the price point. I ordered the size 3 and they fit his foot perfectly! Aber vielleicht gibt es dann gar keine Handys mehr für solche Halter. Are they worth the full price I paid of £179? Probably not but as Im not just paying for the earbuds, Im paying for research, the materials, everyone involved in production, updates, delivering and so on, I get the price so I guess its fair and they are £40 cheaper than Apples earpods. The rubber cord started to kink and bend a lot after a while (as cords do) but it started to interfere with the connection to the device and eventually didnt work at all. So I think it all comes down to the price youre willing to pay. Finally, after an hour and a half of rigorous workout, these earbuds stayed put, and even forgot I had them on. It really came to a head today when the boom arm base decided to fail and fall off my desk. Tip: I?ve come to learn over the years that RTA furniture tends to need a little fine tuning to be the best it can be. These overall work well and do a pretty good impression of the beatsx.
