What ear plugs/buds do you think are best?
I myself was quite content with shure 210.
You're gonna luv the D2 when it arrives
I took an eternity deciding what type of earbud to replace my old Sony's with, and ended up getting the Ultimate Ears Super.fi 5 Pro from
www.earphonesolutions.com I'm very happy with the choice and earphone solutions were great to deal with.
Being an inner ear system it took a few days to get used to them ( as with any inner ear model ) but now I can wear them for hours at a time and not notice them there. There is fantastic isolation of outside noises with them in use, which can be of benefit when riding on noisy trains or buses or planes and the likes. One downfall though with these inner ear systems is that when walking/jogging/running the sounds of the footsteps is more readily felt/heard in the ear.
I believe your Shure SE210's are very comfortable to use also, and I would suggest you wait until the D2 arrives to try with it first before considering a change to the earbuds ( if at all ). The EQ system in the D2 is very versatile and should be able to accommodate any corrections you may feel necessary for the 210's.
Have fun with your new toy and be sure to spend lots of time on the D2 forum I mentioned in the post above.
Cheers,
Russ
