The glass panel on the top is opaque when the speaker is inactive, but a swirling orb of coloured light appears when Siri is listening or processing, while a smaller white orb gently oscillates as music plays. It’s a classy and alluring touch beyond anything you’ll get from any other similarly priced speaker. It makes the wraparound lightstrip of the Amazon Echo look as sophisticated and seductive as a set of traffic lights. There are no physical buttons on the HomePod Mini. I am interested in Frequency response and sensitivity especially. When the top panel is lit, it reveals otherwise near-invisible plus and minus symbols that, when touched, raise or lower the volume. Anyone have specifications for these I have the 25 tall 1972/3 model. A tap of the centre of the panel will pause or resume your music, a double-tap skips forward and a triple-tap skips back. A long press, meanwhile, sets Siri to listening mode. At its core, though, this is designed as a hands-off affair. There are no physical audio connections, either, nor does it support Bluetooth for playback. Even the power cable is fixed, terminating at the other end to a USB-C plug that slips into the same 20W wall charger that’s bundled with the company’s higher-end iPads. If you’re wondering whether that means the HomePod Mini can be powered off the USB-C socket of a Mac it can’t. At least, it wouldn’t work when plugged into our MacBook Pro, with an angry-looking pulsating orange light indicating the HomePod Mini’s displeasure at being asked to perform on an underpowered port.
