The earphones work very well and allow me to listen to music on my computer without disturbing my roommate (I am currently in the hospital). 5 Men, figuring that they would overall be an 8. Range was as good as any similar style earbuds without dropping out over a room away. Great sound but kept falling from my ears, which has ben a problem with all similar styles of ear buds. Be forewarned: a well-recorded vocal track through the 650 may bring tears to your eyes, and thats why I kept the 650 and returned the 600. it’s just cheap not cute in person. In addition to noise cancellation, you can easily control volume, pairing, track selection and phone calls. Update-I really liked these slides, although they are cut very big! I was a little worried based on the price but I’m pleased to say this thing is awesome. 60 m groß bin hab ich was gesucht das nicht zu lang ist.
