I used automotive de-pinning tools with my um pro 10 & 20. The larger of the two in this picture (top left), as it is slightly thicker and about the same height as the MMCX extends on the Westones./QUOTE]
thanks
assassin10000 i have ordered some from ebay. who knows might need them for car repairs one day.
i was going to do some back and forth testing but this issue is a bit of a pain.
sonically they sound quite good - plenty powerful amps as i am only driving at 1/3 volume. first impressions say the sound is inferior to wired in extension on both ends and headspace (this could be one and the same thing causing this impression). Hopefully the low power needed to drive BA drivers results in good battery life.
fit: the unit is very light but the cable seems a little short and the unit feels a little high up on the ear. it also wobbles around shaking the head left to right - when compared to the Fiio utws1.
convenience: positive - the case is great with the auto on/off by removing and replacing the unit. negative - case is on the big side and about 2/3 of a glasses case. this is fine when I plan to have a bag but when i am on public transport to and from work i like to have just the phone and wallet. this may add unwanted bulk to the pockets.
With drivers attached - the lid flips open very easily as there is pressure from the IEMs and the clasp is very weak.
I will keep using it over the next few weeks and see which situations these end up replacing my cabled pairs. I will be leaving the w60 (favourite pair) as wired to maximize SQ when I demand it and use the w30 and ue900s as portable.
I'm probably being a little nitpicking here but these are the first impressions.
