hi all,
i was looking for a good opportunity to buy these headphones for a long time, as i had, and still am, loving the rs180.
the only reason i held off for so long (since release) was the very steep price.
last week i finally managed to snatch a pair for a really nice price, and i'm thoroughly enjoying the sound of these.
the plan was to replace the rs180, which i use in office, however, due to all 2.4GHz bands being in use, this won't happen. (i tried them for half an hour and thought the headphones were broken, with the amount of drop-outs i had)
i took them home, let them charge, and have been enjoying them at home without a single drop-out for a few days. (coaxial with my FiiO X5, analogue with my turntable, and optical with my (apple)tv)
something i'm missing with most cans, but not with these, is a very nice balance between bass and treble. great.
i do find the 16 hour charging time for only 8 hours of music a bit strange. the RS180 needs only 6 hours of charging for 24 hours of music. same batteries.
while i understand that there's a lot more happening in the transmissions between the 220 than the 180, i don't get that the charging time must also be tripled.(for instance, the audio on the RS180 is compressed, thus less data must be transmitted per timeframe. this is also the most likely reason why those have little to none dropouts at work)
apart from these headphones, i also tried the RS195, and, although they are marketed as "audiophile grade", they are far from that. even with all the settings and knobs turned to off, the system changes the sound between source, and ears. i was extremely disappointed with that. the RS180, though hardly noticeable to me, messes with loudness levels a bit, and the RS220 doesn't seem to change anything on its own.
for those looking for great wireless headphones, i would recommend these.
and a second pair of triple A eneloop batteries.
P.S. sorry for waking a sleeping thread, but i really wanted to add this. it's hard to get any information on these headphones, that wasn't a direct copy-paste from Sennheisers' marketing department
