Etymotic Evo Earphone, this is Etymotic's long awaited follow up to the Etymotic er4 series. for the first time Etymotic use a multi driver system, the Evo uses 3 BA drivers and retains the deep fit and isolation of the er4 series. They also retain the accuracy in the sound but with more depth to the bass response compared to the ER4.
These come boxed with all tips bar the grey foams for hygiene reasons.

Looking for £315 for these, normal retail price is around the £500 mark. I bought these from HiFi headphones in the UK.
