The guitar strums sometimes sound
brighter than they do on other pairs, and Callahan's vocals sometimes sound more crisp — this sound signature, even with the bass
at low or medium levels, is a lows - and mids - forward affair, with a little less crispness and brightness in the
higher frequencies.
The Momentum In - Ears» sound signature is unique, more
bright (in the
highest frequencies) than crisp (in the
high - mids), and fully capable of delivering powerful, distortion - free bass
at higher volumes.
