If it was me I'd use
www.tenso.com as the forwarding service, and order from
www.amazon.co.jp, I'd throw in the Sony E931 in my order as well.
Noteworthy is also the Audio Technica CM707 which will be released in two days(!) and is available for pre-order.
For the record I bought the E888 from a Sony store in asia on sale for roughly $45 USD so I think these prices are too high, but it's a stunning earphone and well worth it even if it cost $110 USD imho.
Modding does make a difference, however removing the plastic honeycomb piece will decrease the soundstage so there's a trade-off involved.
There are 5 components between the bio-cellulose driver and your ear, as follows:
DRIVER -|> 1.metal grille -> 2.acoustic ricepaper filter -> 3.plastic honeycomb soundstage filter -> 4.rubber ring -> 5.foam cover -|> EAR
The best mod (pure SQ) is 1,2,3.
Best soundstage is 1,2,3,4,5.
Most natural sound is 1. or 1,2.
Most practical is 1,2,3,4.
2 and 5 are not compatible with eachother, so if you don't like 3, use 1,4,5. or 1,5. which sound good.
Without 4, the E888 become fragile, so be careful outdoors, or seal everything in place with a different method like glue.
With only 1, do not let anything touch the driver, it breaks very easily, the sound quality with only 1 isn't teriffic anyway however with 1+ your own material like a thin layer of silk or polyester is noteworthy.
Yes, once upon a time I was excited and bored with this earphone.
