They are good sounding, but very different from the vented versions. The vents sound like a high powered greenback, like the earlier brighter T3120 G12 65s can sound like a greenback. The white label/next version 75 after the vents have a much more noticeable mid scoop. But, they have WAY more mids than any T75 that would follow. My experience is the T75 kept getting more mid scooped as the years went on. In a gradual way.
