What you pay for is what you get...and I think they are worth even more.
I mainly use them for listening to music and they are excellent.

UPDATE: After 1 and a half years of not everyday use, unfortunately one earphone plays very low. I never dropped them or used them roughly.
Unfortunately, not good quality for headphones that cost 100 euros. Plus, I had many problems with the connections (Android) on my phone and tablet. I bought a well-known Chinese brand for 20 euros and for now, it's fine and without any connection issues on my phone. I hope I helped.

Simply perfect sound as befits the company's name. To be honest, I was afraid to buy them... I had tried the Samsung galaxy buds plus (a bit cheaper) and the Bose sport (more expensive) from friends, but in the end the sound is very powerful, deep, perfect bass, the app is very good and simple. The Ambient ware is very good because the headphones block out external sounds quite well, and with this mode, it's perfect to know what's happening around you. As for the battery, I haven't tested it fully, but it lasts a long time. For example, I've used them for 3 gym sessions of 90-100 minutes each and I haven't charged the case yet and it's still at 100%, I have no idea how!! The quality of the buds is simply premium and has no comparison with Samsung, especially the case with its leather style (just like the buds), it satisfies even the most demanding person!! The app is PERFECT!! ...at least in my ears...comfortable...I forget that I'm wearing them...at least for up to two and a half hours continuously that I've tested them. If you have the money for these, there is no reason to go for more expensive ones unless you want ANC, in which case the premium ones above 250 euros are the only way to go. However, because I own the Bose QC 25 and 35, I don't believe you will ever get the strong ANC from in-ear as you would from over-ear! That's just my personal opinion. Happy New Year!!
I hope I helped.
