Our Verdict

Etymotic ER4XR

Etymotic Research HF5

The Etymotic ER4XR are better critical listening headphones than the Etymotic Research HF5. The ER4XR have a better more premium build quality with dense durable earbuds and a detachable, braided audio cable that you can replace if it ever gets damaged. They also have a slightly better sound than the HF5 with more bass. However, the HF5 are a better value for your money since they cost much less for a similar sound. They also isolate as much as the ER4XR in noisy conditions which makes them a great choice for loud noisy environments and for commuting.
