I was blown away by the sound produced by these earphones, certainly didn't expect such a good sound for the price I paid which were bought when on special offer, so not full price I hasten to add. I would consider myself a bit of an audiophile and can distinguish good from bad sound quality, I have owned various brands, some at the high end of the price range and still they do not compare to these.
I have read reviews about the titan range, some not favourable regarding build quality, some breaking etc. But i took the chance and am glad I did. I use these regularly 4-5 times a week at the gym and get through earphones at the rate of about every 6-9 months. I normally just buy a new pair as they simply don't last long whatever the brand. I usually try a different brand or model when buying another set, but in this case, a first, I will definitely buy another pair of these when they are past their usage.
To summarise, the volume produced by these is excellent, as with other brands I had to have the volume up full on my ipod but with these it is about 75% and more than adequate. I only load tracks at 320kbps to ensure better sound quality. The bass is full-on but warm, mids are very good across the range and the treble is crisp and clear without being too sharp. They do not distort and handle everything I have thrown at them. The cable is quite thin so will probably suffer from the usual internal breakage at some time but until then I am over the moon with these.
Buy them! You won't be disappointed.
