Strengths: Great Looks. Associated with a proven and respected sports brand.
Weaknesses: Do not fit well, low quality sound, lacks real punch in the bass department.
Overall: I have had 2 pairs of sennheiser earphones and twice I have been disappointed with the quality of sound from them. These earphones are no different and to me, the name is nothing special. I sent them back. I stick to JVC and Panasonic. They may not have the sports brand association but for me the sound, fit AND price are better. I do not think these earphones represent value for money.
