After reading a whole lot of reviews, test-results and user opinions, I opted for the Westone 3 in-ear headphones (some people rather call them "monitors"). What can I say: I am just a user and have neither the equipment, nor the knowledge ...Read moreor time to perform high-tech measurements. However, I can consider myself to be pretty "sharp-eared" and I enjoy spending money on good audio equipment. These in-ears are all what you can read about them: great sound stage (for in-ears), crisp and moderate, deep enough bass and dicriminating, loud and clear, whispering if necessary. Simply the best (and, of course, most expensive) in-earphones I ever had. Work perfectly with both my Cowon C2 and SanDisk Clip +8 (yes, the little one!). They come well equipped with accessories, even a headphone amplifier was included. My music: well engineered records, such as Pink Floyd, Dire Straits, classical music by Deutsche Gramophon , to mention a few. Bottomline: you get what you pay for. Perfect headphones for my ears. Worth every penny, would buy them again any time.
