I got the anc 3 and the anc 4 and the bass on the 4's is really good also they are really good during my workout other than when I'm jumping around get a lot of extra noise but I guess that's going to happen with any in-ear buds I also got the lux headphones in mauve bass left a lot to be desired on those also they feel pretty cheap but I love the app with the equalizer options very good job on that I'm only keeping the anc 4's I'm returning the other 2
Better than any others I've used, this brand or any other. App doesn't control noise options without using the selector touch controls on the device physically first and EQ option for custom makes the sound quality terrible even if set to the same output levels as default options but sound quality is good on default options and the noise cancelling is impressive. Less noise than earplugs without no audio playing and don't fall out when being knocked around constantly from bad terrain. Touch controls are complicated to use slide feature when you can't see where your touching it at first and it's going to do something when you touch it so just constant finding where to touch then fixing whatever is messed up from touching it and then adjusting the volume. Easier to just pause or use the output devices controls
I use these earphones at the gym and the sound is great. The app works great for all the controls. The only problems I've had is the left side of my unit is faulty where there is a lot of static and interference no matter what device I connect it to.
