Far better than you'd expect from bundled 'phones!

Summary: Have these from a HTC Desire I got 4 years ago. Thought I'd give them a quick test while looking for replacements for my ageing (but still working) Sennheiser MX550 earphones. Not quite the quality or volume of the Sennheisers but not far off.
