Good sound, improving worthy rest.

+ The sound quality is excellent for InEars this price range, ie. balanced, powerful, transparent than many direct competitors. Addendum: Isolation and volume efficiency are also good, had my iPod Classic from 2007 mostly at considerably operated below 80% maximum volume.
+ Processing makes a (superficial, see below) good impression, Case is included.

- Noticeable noise cable to the 30cm long ends of the two cable strands, which pass into the earpieces. Can be avoided by passing the cable (as recommended by the manufacturer) on the ears. Unfortunately, these wire strands are somewhat rigid.
- After about 7 months of normal use sudden loose connection at the plug. Addendum: I was reimbursed by Amazon after a complaint and return of the original purchase price.
