Nice clear mids & decent bass, in an attractive device, make this an all-around winner.On the negative side: there's a mostly unnecessary app, oversized volume buttons, and a I'd prefer it had a USB-C power connector instead of the old "micro" connector.Over all, this is a great speaker. It also looks really nice, and feels solid in-hand. The UE is small/light enough that I use it as my travel speaker, although I prefer the boom-ier bass on my (heavier) JBL for workout and party music at home.This speaker sounds good, but not obtrusive-- natural for various genres. The default tuning is "fine". Unusual for a Bluetooth speaker, there is an EQ feature on the app, but it doesn't let you turn one band up without decreasing the others. Good for tuning the sound quality for eg, spoken podcasts, but you can't turn up the bass or the treble like you might on a usual sound system.The app also allows using the speaker's top "smart" button to automatically launch playlists without otherwise interacting with a device. A clever idea, but since I usually use an AI (like Google Assistant) I find it unnnecessary, and better to not have too many random apps installed. The speaker works beautifully without the app-- totally optional.I used to buy Logitech PC speakers long ago, and they still make good "gaming" speakers. It's interesting Logi acquired Ultimate Ears, a brand I hadn't heard of before. A good move on their part, as this is one of the two best speakers I tested recently in my search for the perfect hardware.Highly Recommended.
