Excerpt: I purchased my first pair of Sennheiser headphones in 1970. I was pleased then and I'm pleased now. The CX 300-II "in-ear headphones" are a sound value. The bass is solid, but not artificial. The highs are crisp and the mid-range is acceptable. A great improvement over my Samsung in-ear headphones that I purchased circa 2012. For the money this one is a winner!
Pros: Comfortable, Durable, Good Bass, Good Value, Great Sound, Lightweight
Excerpt: I bought my pair of Sennheiser earphones because they were on sale for $29.99, down from their common price of $59.99. I needed something to accompany my portable media player while I was on a trip. From my experience with Sennheiser, I assumed these would be quite good.
Excerpt: I use these both to listen to music on my mobile devices as well as in ears monitors for the live band setting. These have great bass response, and maintain good clarity at medium to medium loud volumes. They do start breaking up at very loud volumes as do all single driver in ears.
Excerpt: you're essentially getting what you pay for here. These are certainly better than the "white ear buds", but the "bass-driven sound" comes with a mid-range boost that sucks some of the warmth out of the music. i would prefer a more balanced soundThat being said, Sennheiser is still my prefered brand of headphones, and the more you pay, the better the product.
Excerpt: I'm a big fan of these headphones. This is my third or fourth pair, not because they aren't durable, but because I use them so much, and tend to not be too careful with them. Great sound for the price, and I find them incredibly comfortable.
