As several have pointed out, you can get a few Teenage Engineering products at IKEA. And they are surprisingly good (and not awfully expensive). I replaced my Sonos with a Frekvens speaker (with a subwoofer) at the cabin for three reasons: - It works with bluetooth, and to be frank, the Sonos' firmware is terrible if you have dicky wifi - It can handle audio that has been sped up (like Audible at 1.5-1.7 times normal speed, which is the speed range I currently listen to audio books at). The Sonos can't without getting severe hickups. - The Frekvens has room for a battery so I can take it out on the deck Actually, we brought the Sonos home to have in my wife's home office but she sto^H^H^Hborrowed my second Frekvens speaker because she is "tired of dealing with all the shit the Sonos throws up".
