The RSM custom in ear monitor is a four-driver, three-way design with 2 woofers, 1 mid-range, and 1 tweeter. It has the power and presence to handle any stage, and the clarity and detail to enjoy while on the bus, plane or easy chair.
“ These IEMs have an MRSP of $40. For that price they are not worth it. However, in many discount places, especially in Canada, you may find these @ $15 or less. If you find them for this price, grab them. I personally paid $10. Sound is great for the price. They look very rugged and feel solid, I believe they are made from aluminum. The cord is also tangle free and feels very nice....” --thug behram
