Sound quality: JAM's Symphony (HX-W14901) had good overall sound quality. Bass has good impact but is a bit boomy, prominent and goes somewhat deep. Midrange is a somewhat hazy. Treble is a bit subdued, smeared and upper treble is muted. Doesn't do a good job of recovering room ambience and is somewhat congested. Wifi and wired sound quality are similar. Provides a decent volume level in a large sized room. As a stereo pair they can be placed to provide better stereo separation than many other models and sound quality improves however, it is echoey and bass is somewhat prominent, at the time of testing there was a delay between the right/left channels which creates a slight doubling effect and one speaker was slightly louder than the other even with app volume levels being equal, it would have scored a good without these issues but with the delay and balance issue it was only fair.
Ease of use: We found the JAM Symphony to be good overall. Connecting to a Wi-Fi network is straight forward. DLNA: Setup instructions are ambiguous, there is no explanation as to how to actually make the connection. Volume control is a multifunction +/- buttons which also can accidentally skip tracks forward/back. Also indicates with a tone when max volume is reached. Mute controls are low contrast labeled Play/Pause control that is well placed, but no indication on unit when muting is engaged. Switching sources: Plug and unplug - The line input has priority over wifi when plugged in with a delay. Line-in port is poorly labeled - low contrast. Remote app: Volume control has a clear volume symbol when depressed brings up a volume slider which lacks numerical or index markings but clearly indicates position. Play/pause control which is clearly labeled and only mutes wifi content not line-in. App lacks a source selector for aux input and can't switch to wifi while line-in is connected. Transport controls are obvious, good contrast, standard symbols, play/pause, skip, and scrub bar provision but no scan.
