Sound quality: Bose's SoundTouch 20 Series III WiFi had good sound quality overall. Bass has good impact, goes somewhat deep, but is prominent and boomy. Midrange is fairly even but slightly gritty and is somewhat overwhelmed by the bass. Treble is extended but is prominent and sizzly. Does a so-so job of recovering room ambience and is a somewhat congested. Fine detail is lacking. No significant difference between Wifi, Bluetooth and wired sound quality. Provides a high volume level in a medium sized room.
Ease of use: We found the system's ease of use to be very good overall. The Bose Sound Touch 20 Series III Connecting to a Wi-Fi network is straight forward but a bit tedious and intrusive since you can't complete the setup without registering the unit which requires providing some personal information. Bluetooth pairing: pairing requires a press well marked button which is also marked multifunction then selection of unit from Bluetooth selection list on source device; unit provides an obvious indication that the unit is in pairing mode as well as when pairing has actually occurred. The speaker and remote have well marked controls that are easy to use, and the speaker has a very informative display.
