Ok. So, I ordered a set of T-100 Comply tips (Medium) and holy cow. Not only do I have pure isolation, but they are so comfortable and I'm not getting any negative sound qualities. Additionally, the bass response has improved. Still tight and concise, obviously, but more complete now. I've been listening to them for a few days now and couldn't be happier.
The other thing that I'm amazed by is how light these things feel in my ear. At times I can't tell I have anything in at all. And, the Comply tips are great when you're chewing/yawning, etc. The original tips crackled a lot as I moved my mouth. With these foam tips, it hides almost all of it.
I'm glad I didn't return them and heeded the educated advice from everyone on here. I appreciate all the help. For me, I feel like I landed in the perfect spot of balancing cost and gaining as much sound quality as possible for my budget.
. I'm glad it worked out well.
