Your recommendations have worked out great for me so far. I especially like trying out the cheap IEMs. Some of them are amazing for the price. The 8320 Monoprice IEMs sound much better after a long grueling burn in. I had them going for about 2 weeks straight. They sound much better now. Also the Philips SHE3580 you recommended sound incredible for the bass and the super low price.
For my music listening, I will stick with the TF10s. To my ears, nothing else I've tried can't even get close to them. I've got B&W and McIntosh for my home audio (not rich - traded work for hifi), and, to me, the TF10s sound just like my home system. And that is awesome.
My next IEMs will either be customs, or maybe the Westone UMX3. My IEMs always double as hearing protection. I'm a woodworker, and I wear earphones for 8+ hours a day. Sometimes with Sound Isolating Earmuffs worn over the IEMs (awesome if you really want to hear JUST the music).
