My main evaluation criterion is the sound. For a mobile device this is the best I've heard so far. Of course, a hi-fi system sounds better. But with the Bose SoundLink Mini makes fun challenging music. Here someone wrote when Adele had the box fit, I feel not so. Beth Hart and Joe Bonamassa I can thus listen with pleasure. Even songs that demand a lot of boxes, such as "In the Air Tonight" by Phil Collins, or "Brothers in Arms" by Dire Straits (years test CD with audio) can be heard with time entertainment. The current radio hits go anyway. The bass is for the size amazingly well and accurately. Again: the hi-fi system can again much better - but the comparison is not fair, the field of application different! Heard compared a product from JBL and Sony SRS-X5 NFC. The Bose sound much better to my ears. Sounds as good as the Sonos Play1, but is smaller and the battery power of mobile (and does not require a Wi-Fi). -control Problems -Bluetooth Pairing problems -Of course the Euro plug was there (which had some reviewers criticized) -schickes design - makes a very robust impression -Laden In shell possible, just as well as if you connect the charging cable directly to the machine
