Love your speakers but wish they were wireless? Enter Beep ($106). Think of it is as a wireless speaker converter, transforming pretty much any speaker with a Aux input, RCA jack, or optical input into a fully functional wireless speaker. Simply plug Beep in, hook up your speakers, enter your Wi-Fi password and you’re done. You can control Beep either through an iOS or Android app, and it wirelessly plays any music you have on your phone, both in your library and on your favorite music apps. Connect as many speakers as you want with multiple Beeps, and music is synched automatically. You can also start and stop music with one touch directly on the Beep or adjust volume with the built-in dial. If you want one, you can pre-order now with a $50 discount (they’re $156 normally), with shipping starting this fall.
