Tennmak Pro or Piano, both cost £22 on the rain forest.
The Pro has pause and skip forward & back controls while the Piano has a straight through silver cable, so no controls.
Sound wise, the Pro has stronger mids, more rolled off highs and bass is mostly mid bass rather than sub bass, probably better for female vocals.
The Piano is a different beast, it has good mids but they are a bit more recessed than with the Pro but the highs are more extended, providing a nice bit of sparkle without sounding sibilant. The bass is stupendous, it's powerful and pretty quick for a dynamic driver and goes very, very low, so you get plenty of growl and thud.
I have both of them and my favourite is the Piano, which is sharing ear time with my Brainwavz B100s.
