The HS520 look good, but that’s about as far as it gets. Even though they aren’t overly expensive, you can get a far superior product for little more than what these are worth.

We can’t recommend these headphones. The sound quality is below average, they lack bass and they’re uncomfortable. A disappointing effort.

The MX70 headphones do not live up to the reputation created by Sennheiser's other earbud products. The clip on design means it is difficult to make the earbuds sit properly and their sound quality leaves quite a bit to be desired.
