These are by far the smallest and most portable phones on test in this round-up. The small cup size explains why sound does tend to leak out, but on the upside they're comfortable, unobtrusive and fold down beautifully to take up minimal space.
Like most of the other units on test, they sport inline controls that include a mic for hands-free mobile phone use. The built-in TriPort technology, designed to produce tonally balanced audio in lightweight phones, does a sterling job with mid- and top-end sounds, delivering crystal-clear audio. It does, however, lack a little punch in the bass stakes compared to other headphones here - understandable considering its size.
We like: small footprint, pack away tightly; good mid and top-end frequencies
We don't like: bass lacks some resonance; feels slightly plasticky; noise leaks out
