Near the base of the speaker is a short, thin status LED, while a second blue LED near the top of the speaker glows from behind the fabric when Alexa is listening or speaking. Touch-sensitive controls on top of the Denon Home 150 (pictured) and the Home 250 light up when your hand approaches. Measuring 7.4 x 4.7 x 4.7 (HxWxD), the short, squat Denon Home 150 feels solid and substantial at 3.7 pounds, with a fabric-wrapped circumference and a glossy top with touch-sensitive controls that appear when the speaker detects a nearby hand.
