"First and foremost, the OB-4 sounds exceptional. Was not expecting such detailed and loud output from a component so compact. The Bluetooth connection was very reliable, and the FM radio option is useful to combat streaming burnout. Lastly, the disk function and effects are super-fun, they add a creative (magical!) element to the listening experience." - TTL
