well for a commuter they are great, in terms of vs the rest of the E series, well these have a very different sound. These have a more balanced and coherent sound, the E10 and E50 have more air and separation but do sometimes sound a little detached. These are in my opinion a good started Audiophile IEM, as they lean towards a more natural and balanced sound, rather than boosted bass and sparkly highs. These sound more together and complete, a very worthy IEM at this price point.
