“How’s the sound? In a word, perfect. W3 transmits your lossless audio without any snap, crackle, or pop. If you are using external USB batteries attached to each sender and receiver you can place your sound source, such as an iPhone or iPad and a powered speaker anywhere. Pool party! Camping trip! Beach vacation! College dorm! Patio barbecue! Multi-room house! The opportunities for stellar sound are infinite, and are not limited to a computer as the source. Audioengine produces innovative solutions for the best possible audio experiences. Their W3 Premium Wireless Audio Adapter is another winner for them and for us.” —— mymac.com
