I've had the GR10 for quite a long time now, and it's been my go-to IEM for a large part of that time. It's recently been displaced by a few additions to the collections. One of them (the JVC FX-850) also provided the opportunity to try the JVC Spiral Dots tips on the GR10. All I can say is: to all those that feel that the GR10 are somewhat lacking in bass, switching tips to the JVC spiral dots ones helps, IMHO, quite a lot .
Thanks for the tip geagle :) do you know anywhere i can buy them in the UK/EU. i saw some on ebay from Japan but they were $50 !!
