Nice,looks like the housing is just small like vsonic vco2..........

There so small without the tips I could fit them in my ear canal.

Thank you acain!! I have enjoyed reading your comments and impressions. I really want to give them a try. I'm always interested in buds that I could used in my job, with a good construction, comfortable, discreet and above all with a hight quality sound. Very nice review!!! 

Thanks there perfect for highly active jobs.

Thank for review, cool spec.
