Unfortunately, the DTX 60 has significant weaknesses in the bass, it sounds weak and dull. I tried with different settings of Equilizers at various music pieces of my iPods. Also loudness or more bass has the listening result is not significantly improved. As a current comparison I used my previous Sennheiser CX 300, which sounds much better and more powerful.
I'll probably return these earphones again and again to grab Sennheiser. Especially since this is going to have even 10 cheaper.
