Scott has been testing a new in-ear monitor headphone called the REVONEXT, and when you put on the proper "tips" for your hears, the sound is really nice. Good bass, ground stereo sound. But if you use the wrong size tips, the sound degrades to being very tinny. They come with three different tip sizes and are only $30. But they're also wired headphones, so if you're a current iPhone user, you'll need a lightning adapter. Periodic Audio and Comply sell memory foam ear tips that will also work for them. Another cool function is that the cable that the IEMs use aredetachable.
