The sound is the best quality I've heard from any set of headphones I've ever used. It has the warmth and range of tonal quality I've only ever associated with top of the line speakers before. You aren't normally able to distinguish between the individual voices singing five part harmony when listening to music through speakers let alone ear buds, but the Timbre Pro not only delivers rich sound the separation of the different ranges and frequencies is so clear you hear each voice as clearly as the lead vocals. The same goes for individual instruments, including some percussion you almost never hear because they are usually lost in the wash of sound. You could listen to everything from classical to hip hop on these with equal enjoyment
Like most earbuds they come with three different sizes and shapes of replacement buds for inserting into your ear. In this case however, they not only fit snugly into your ears without hurting they also successfully block out a great deal of surrounding background noise. This means you don't have to risk deafness by cranking the volume to listen to your favourite tunes while walking down a busy street. I tested them on a major street walking on the sidewalk right beside two lanes of traffic and didn't have to adjust the volume on my player once and was able to set it at half the level I had with other headphones.
While the Timbre PRO earbuds with microphone might seem pricey at $49.99 ($39.99 without microphone), as far as I'm concerned they are worth every penny. After years of having to listen to barely adequate sound through less than comfortable equipment, it's a joy to be able to enjoy the same quality of fidelity that I used to only ever associate with high quality speakers. As has been the case with home audio equipment in the past there is no point in spending a lot of money on a music player if your headphones suck. If you care about the music you listen to the Timbre PRO earbuds are worth every penny.
