I ordered the Tenores from Amazon and received them last week. If I use the medium tips that came with them and place them far enough in my ears to get a complete seal, their sound is extremely bass heavy. With a less than perfect seal, the balance is much better, with the smooth mids and highs nicely integrated with the bass. My ER4's require a complete seal to get decent bass response. DId I get one of the bass heavy ones? Or are these made for shallow insertion? With shallow insertion, they are still have more bass than the Ety's.
