I got mine from MP4Nation...  Here's what I received from them on 11/30/13...   We have been informed by iBasso that they will handle the replacement directly with customers now for this issue.  If you contact them directly they will handle the replacement. They will provide you information on...

iBasso is handling all the warranty work for MP4Nation on iBasso products.  I learned this after a LOT of back and forth eMails b/c the repair responsibility changed in mid-stream.  My player's pause/play button was non-functional.  After writing to iBasso (service@ibasso.com NOT the iBasso web...

Good for you.  Mine went out yesterday after some runaround between the vendor and the manufacturer.  I had the same problem with the play/pause button non-functional.  I'm without a decent FLAC player so I'm using my Clip-Zip as a mediocre substitute.   How did they ship your replacement and...

Good luck if your DX50 arrives broken like mine did. $25 & two weeks to send the RMA back (usps intl.) to Hong Hong then waiting for the next batch from iBasso. Amazon & Parts Express for the X3 are WAY more convenient. The X3 is $50 less expensive. They have stock ready to ship, ship fast &...

Yeah - it might be interesting to others how iBasso deals with defective units.  I'm certainly interested to find out.  China is a long way from Upstate New York (USA).  :-)

Guys - Thanks for the bad news :-)  I was afraid of that.  I'll wait to see what the iBasso guys say and report back to this thread.

OK - I'm in the club now too.  Got mine a few days ago from MP4Nation and am very happy with the sound through my ancient history Sennheiser 580s.   I poked around this forum and others to come to a decision about Fiio vs. iBasso and went with iBasso.  Got mine from batch 9 with 1.2.5...
