Pros: The block out a lot of ambient noise.
Cons: They don't hold up to normal wear and tear.
I received these headphones for a Christmas present after doing A LOT of research. I enjoyed them at first, but after less than 3 months the cord at the jack began to loosen, even though I religiously put them back into their case after every use. By the time I had owned them for 6 months, they were no longer working.
This part of the headphone is not covered by warranty, so I no longer have the headphones, or the money.
Great.




I've had really cheap Sennheiser bottom-end in-ears and (dare I say it) stock earbuds that've lasted longer than that. Klipsch's in-ears are known for horrible durability, and they didn't fix any of that with the S5i "rugged" version of the S4 design.
