Review on Mighty Vibe Spotify and Amazon Music Player - Bluetooth & Wired Headphones - 1,000+ Song Storage - Phone-Free - Blue by Keith Morris

Used this for a few weeks training and climbing, really great technology at a very fair price. Some people seem to have trouble syncing it to their phone/Spotify, but for me it was quick and painless, so no complaints. My main complaint is the audio quality in wired mode. I originally planned to use it with some wired headphones but the sound quality was pretty poor compared to my Samsung S9. I bought bluetooth headphones instead and the sound quality is much better there. Usually the opposite is true, but I think this unit just has a very weak cheap amp. Stick with BT and you'll be fine. Overall solid four stars. Certain purchase.
