If the novelty of the Ring Boxx wears off too soon, just throw one of these into the mix. The MP3 Bell includes 125 different sounds and effects, or you can upload 30 seconds from your favorite hit. Plugs in via USB to grab the audio – capable of 100db output – but works wirelessly once installed. 3 AA batteries gets you 3 – 4 years of use, but you’ll need to hardwire the remote.
Available here for $100.
