Hi Larry,
The Shure SE210 is not a great earphone in my opinion. This was actually my first ever pair of IEMs and I was bitterly disappointed. It made me wonder what all the fuss was about!
A couple of good choices at around the £80 mark with be the
Phonak Audeo PFE 012 (very well balanced with excellent clarity),
Beyerdynamic DTX100 (lots of bass, but good fun) and the
Klipsch S4 (definitely at the warmer end of the scale at the expense of accuracy, but a solid choice).
