+1 I like the new ones better as well. Never did try the Ebay - Chinese made ones.
Just tried some cheap Chinese ones from ebay ($10 for 10) and they made the bass sound muddy and highs weren't crisp. Tried one with socket saver other without and there was difference between the two. Tried this with the Novib socket savers and didn't notice a difference between the two, I guess you get what you pay for sometimes.
