Sound quality: LG's MusicFlow H4 had fair overall sound quality. Bass is subdued with so-so impact, lacks definition and deep bass is lacking. Midrange is a bit lean, hazy, and grainy. Treble is smeared, spitty and slightly subdued. Doesn't do a good job of recovering room ambience and is hazy and congested. No significant difference between WiFi and wired sound quality. Although Bluetooth sounds similar to the other inputs, it has static-like sound quality. When used as a stereo pair, the sound quality is slightly improved but is still in the fair range. The sound is similar but slightly less congested, the room ambience recovery improves to so-so, and it provides a decent stereo image which extends somewhat above the speakers but not beyond the width of the stereo pair. When used as either a single speaker or as a stereo pair it provides a decent volume level in a small-sized room. When audio was muted and then unmuted, the speakers play out of sync with each other.
Ease of use: We found the system's ease of use to be very good overall. It was very easy to connect the LG MusicFlow H4 to a WiFi network. WiFi setup requires the installation of the Music Flow App, pressing a button on the unit, and following the step-by-step wizard on the app. This also requires selecting the network and inputting the network password.There is an audible indicator of successful connection. Bluetooth pairing is adequate, but it requires that you press an ambiguously marked button then select the unit from the source device. DLNA: Although it is automatically part of the WiFi setup, it is not clear that it is setup and instructions explain other steps that may be needed to insure DLNA setup, which requires external help for the other peripherals that may be affected in setup. Console controls are generally very good, though mixed with ambiguous and unlabeled multifunctions.
