I know I'm being pedantic, and you probably didn't mean it like this, but as a permanent tinnitus sufferer, I abhor it when flippant remarks like this are stated.
One of the most common causes of tinnitus is listening too loud. You damage your hearing, and the brain basically replaces the frequency you can't hear by a high pitched ringing. I would give
anything to simply be able to listen to silence again. Its something I can't do now - the ringing is always there. You learn to live with it so that most times you don't notice it, but when it is quiet, its impossible to block it out. And for anyone interested - mine wasn't listening too loud for extended periods of time, it was one concert (a 3 hour event) where I was stupid enough not to take hearing protection, and the organisers had the system jacked up too loud.
Back to George's comments.
- Stating that you won't get tinnitus or listener fatigue and you can basically listen louder is like saying that you can drive as fast as you like with a new Ferrari, and because of the road handling, you don't need to worry about a seat-belt. It is patently, utterly wrong. Always use restraint with IEMs, and try to keep the volume levels well under 80dB.
- No matter what DAP you have - smooth or sharp, thin or full bodied - they can all cause tinnitus or hearing damage if you listen too loud.
- The X5iii does not "work better" if listened to at high volumes. Its better for your long term hearing if you train yourself to listen at safe volumes - and I can assure you that at 65-75dB you can still get all the enjoyment you need from the X5iii.
