Long time reader, first time poster here!
So I bought a Chord Mojo of Amazon (UK) last week, and I'm really impressed with the way it's driving my HD650s. The only issue I have is that just before it's finished charging it starts making a hissing/high pitched buzzing noise. I've read that changing charger/cables can make a difference, so I've used an Apple charger, a Samsung charger, a Sony charger and both USB 2.0 and 3.1 connections to charge with a variety of USB cables and the noise still remains.
I should say that within a minute or two of the hissing/buzzing starting the white light turns off (IE charting finished) and the unit gives me 8-10hrs of playback after unplugging. I also don't get any charging noise throughout the rest of the charging cycle...only during the last couple of minutes when the charging is almost complete.
Do any of you have experience with the Chord Mojo? Can you comment on why the noise is happening and what I can do to prevent it? And most importantly - should I return my Mojo and have it replaced, or will I end up with the same issues if I get a replacement unit?
Thanks in advance for your help.
