Customer Review - Verified Purchase

Best sounding earbuds I've used. Wide, really wide, soundstage, great detail, solid, clean bass. Smooth, satisfying mids. The controls are well designed and pairing was easy. Touch earbud touchpad for 3 seconds and it says "pairing" so you know it's pairing. No putting it back into the case and taking them out again multiple times to get them to pair again like with some earbuds. Comfortable enough, though it could be better. The squarish shape isn't the best fitting for ears. Would've liked to see the case have 4 LEDs for power level instead of a single LED with multiple colors. With such a tiny LED, the color is not that easy to make out. Even cheap $30 BT earbuds have multiple LEDs so I'm not sure why Sennheiser couldn't have them here too. The Sennheiser Smart Control app is easy to use and works well. It allows you to tweak the EQ, see the battery level of the earbuds and update firmware of the earbuds.

The overall package (the case, the earbuds exterior, the box it came in) is very basic. If you're looking for something fancy and nice looking to impress your friends, these will not. The earbuds themselves are not sexy looking or stylish or flush fitting in your ear, they are on the bigger side and stick out of your ears a bit. If you're vain and care about that, then these are probably not for you. No ANC, obviously, or ambient sound pass through so if those features are requirements, you should look elsewhere. No sweat/water resistance either, so not so good for working out or using in the rain.

But if you don't want yet another muddled, overly bass-boosted, small soundstage TWS, if really excellent sound quality is way up there in importance and you're looking for a convenient, highly portable way to really enjoy your music listening experience for a not-cheap-but-not-super-expensive-either price, these fit the bill very nicely.
