Sound quality: JAM's Classic 2.0 had poor sound quality overall. What little bass there is has little impact is subdued and deep bass is lacking. Midrange is telephone-like, rough, hazy congested. Treble is subdued and smeared. Doesn't do a good job recovering room ambience, sounds congested and is lacking in detail and is generally distorted getting worse at higher volume levels. Provides a decent volume level in a small room but is better suited for near field listening. The speaker is monophonic.
Ease of use: We found the JAM Classic 2.0 ease of use to be very good overall. Bluetooth pairing was excellent as the device is always in pairing mode when not paired. The volume controls are low contrast (+/-) buttons, has max volume audible indicator and is also an unlabeled multi-function to skip tracks. Switching inputs involves plug unplug where the line input has priority over Bluetooth. Aux jack input label is difficult to read.
