With its spherical shape and high-gloss finish, the Zemi Aria wireless speaker (zemiaudio.com) will catch your eye before its sound fills your ears. The Italian speaker designer Francesco Pellisari collaborated with the London-based architect and industrial designer Ron Arad to create the speaker. It features a 125-watt trio of amplifiers, and the interior of the case is engineered to eliminate unwanted resonance. You can play music from a phone, tablet, or computer through Bluetooth or Apple AirPlay, or you can use the Aria’s input jack to connect a CD player or turntable. The Aria is priced at $799 and is available in white or black.
