The Sennheisers are more expensive in-ears compared to similar rivals.
You wouldn't gather that from a quick inspection of the buds, although the three-button in-line mic looks good, works well and the carry case comes complete with a magnetic clasp. It's a small touch but gives a hint of premium to the buyer.
Jessie J's Nobody's Perfect showcases the Sennheiser's strength with vocals and they communicate the attitude in her voice well.
There's a hint of edginess and thinness in the cymbal crashes, but otherwise they're a very competent pair of in-ears. Bass notes sound weighty but stay disciplined.
