Summary: I had an Etymotic HF3 that I accidentally got caught in my bike and ripped the left ear off. Even after that the right side including the microphone still worked flawlessly. Even though my HF3 was out of warranty, Etymotic support offered to replace it for only $104. I needed something with a microphone because I use it for work, so I tried the Klipsch because I really like their surround speakers and the quality.
Cons: Microphone hangs really low and sound is OK, but not perfect.
Summary: This is a high quality headset that rivals the Bose headsets. The sound quality is great the carry case is cool and helpful and I would recommend this headset to anyone looking for an iPhone or Android headset for their mobile device.
Summary: Klipsch is a great company with a great reputation for speakers. Though these are not your typical speakers that they make, they have a great R+D dept whom I trusted to make a good product. I was not disappointed and in actuality I ended up having my son listen to them and now he has taken them with him for two months as he treks through Europe. He loves them and he is 22yrs old. So all different music sounds great through these earphones.
Summary: These are the best headphones I have owned. I have tried many different headphones but these are by far my favorite. I had the original S4i's and they were just as comfortable. The only thing I did not like about the. Was the cord was easily tangled and did not seem durable. The cord on the new ones seems much more durable and doesn't tangle as easily.
Summary: I love these head phones. I had the original S4 set and those were great. Now I have the S4i and they are equally as great with perfect sound quality, iphone controls, and a more durable cord. Can't recommend them enough! One tip I have is to make custom ear tips for these head phones. All you do is buy a pack of airplane foam tips from a drugstore and cut them down to size. Then buy a leather hole punch and punch a hole in the foam tips and slide them on the headphones.
Summary: These are a great pair of headphones. I spend 3 hours each day on the train to work so having a good set of headphones, earbuds especially is important to me. These do a fantastic job of blocking out all outside sound, have great sound quality, the controls are easy to use and very responsive. The only drawback is the way the controls are situated with regards to how the cable splits between the two ears. Wish that length was a little bit longer.
