I have a set of the Harmon Kardon Soundsticks for my desktop which are excellent. They have beautiful full sound. I was naturally expecting their earphones to be just as high of quality, especially considering the cost. They are not good quality. The highs are sharp and any sounds that enter that range will stand apart from each other. However, in order to even hear the bass, the volume needs to be cranked up and my ears suffered as a result. The bass is quiet and the mids are flat and tinny.
I played 'Money' by Pink Floyd as I always do to test new headphones and I could hardly hear the bass guitar in the beginning. I got nearly as good quality out of my friends $2 set from amazon, and the new apple headphones put these to shame as far as fullness of sound goes. I don't know what the team was thinking, but they must not have used their product because there is no natural balance whatsoever. Little bass to be heard. I will be returning these.
For the first time, I decided to buy myself a really good pair of earphones. So I ended up choosing this pair of HK. It was also my first pair of noise-isolating earphones.
The sound of those earphones is amazing, clear sound with really good bass. It was a joy after years of Apple earbuds utilization! The silicone tips were very comfortable and soft. But the rectangle design of the earphones itself hurt my ears after half an hour of use or so.
But the worst part was, since they are noise-isolating, is the occlusion effect that they produce. I heard my breathing, my steps and the cable rubbing against my clothes or face way too much, and at the end, it gave me headaches... So I had to returned them :-(
