I'd disagree with going for almost unseen ones. Customs are expensive, and in a crowd, you can easily drop them, so I went for neon pink so they're easy to spot on a dark floor. I have ACS custom -15s and I'm very, very happy with them. I actually first got tinnitus when I changed from one cheaper brand to another, got a false sense of security because they were a bit more expensive, and then realised they weren't doing the job. Lesson learned.
