Etymotic ER4 (2015) vs Sennheiser CX Sport

The Etymotic ER4SR (2015) makes for a good, if unremarkable, Earphone for people with a $250 budget.

The Sennheiser CX Sport, however, is merely mediocre at its $121 asking price, when compared to similarly priced products, and won't satisfy the needs of most people.

In either case, we suggest that you first take a look at some other options at the $250 and $130 price points before committing to one of these - it's likely that you'll be able to find some better alternatives.
