Speaker pioneer and manufacturer, PSB, has been getting deeper into the portable audio game over the last several years.


Now they have their first wireless in-ear monitor (“ear buds”). Dubbed the M4U TW1’s, these IEM’s have 6mm dynamic drivers and a high performance mic. They also have touch-sensitive controls for answering and ending calls. These controls also can be used to play, pause, skip, and replay.

The lithium-ion batteries have a life of up to 5 hours. These IEM’s are also weather and sweat resistant for use during workouts or any time I spend five minutes outside here in the South Texas sun 🙂

I like the style of these, especially the way they wrap around behind your ears which provides a secure, discrete look. The casing is a soft rubber which further enhances the comfort level. These are perfect for the newer smart phones and at just $149 per pair, they provide way better sound than the competition. Look for my review of these soon – PSB M4U TW1 Earphones.
