I've been using BD in-ears for years now, and this Particular model is simply the best. The sound quality is what anyone would expect from BD - Supreme. It Tends to be ever so slightly less bassy than my previous DTX101iE and DX120iE, and this is Exactly what I was looking for (never liked too much bass). But more importantly, the build quality has improved tremendously. Large selection of tips is a welcoming addition, but more importantly, the tips are not as thin as flimsy Previously, and do great job isolating external sounds. The hard carrying case is a great change form the previous zip mesh pouch. The jack on extension cord is angled for easier plugging / unplugging, and I am happy for the ability to remove the head unit from the cord as this Simplifies handling during travel. The addition of the bump on the right channel speaker is thoughtful to the point of simplicity. One would be hard pressed to find anything Comparable to the quality of DX160iE at this price level, so definitely the 5 star in-ears!
