I recently got these, i ordered some when i realized that i lost my iems; along with when i ordered my HA-500s. Needless to say these came in earlier than the HA-500s(importing). I broke these in while waiting for my HA-500s to arrive from japan and i have to say these IEMS gave me faith in IEMs, i never considered paying more than 50+$ on iems because i am not a major fan of them from a comfort point but they do stay in when i am Skateboarding and i dont have to worry about breaking them at their price point. Man o man do they exceed everything i was expecting them to do so i went here to see if there was a thread and lone and behold they are here...I couldnt be happier with what JVC is doing to the Headphone Game and the approach they are taking is flawless IMO they are out there and the competition better fell the heat. The HA-500s are exceptional as well Grade A+ products now all i have to do is make sure all my audio files are tip top.
