"The ER-6ic has plenty to offer and whilst not strictly hi-fi, the advantages of custom fitting outweigh the limitations in sound quality. But be warned, the noise cancelling is so good you might not hear your keys falling from your pocket into the street."
- ACS’s custom-fitting mould service
- Unrivalled noise cancelling
- Perfect fit
- Tthe ER-6i is sadly the weak link here
- Poor bass
- Overall sound is on the thin side
- Noise cancelling is almost too good!
