I've had my Roxannes for a little more than three weeks. I ordered clear acrylic ones at the RMAF in October and they were delivered just after Xmas. I had the molds made at the show by JH Audio's staff.
I'm more of a newbie, so I can't provide any lengthy technical review, but can only give some initial impressions. The fit is fine without problem and very comfortable. I only unscrewed the cables once and have not had any problems with the connectors yet but have had limited time to try the IEMs so they have not had a great deal of wear yet.
My main problem is that when I use them with my older iPod (2nd generation) or a 4 year old MacBook Pro, there is quite a bit of hiss or noise without even playing any music. It is drowned out somewhat when I play music, but it is noticeable enough that it would not be practical to use these with either source. If I plug them into my desktop computer headphone output, there is no hiss and the sound is fine. I have also tried them with my iPhone 5 and with my wife's more recent iPod touch and the sound is terrific with both of these sources and there is no baseline background noise or hiss.
I haven't used them enough and am not expert enough to be able to comment on soundstage, etc. but I find the sound very enjoyable when used with the iPhone or newer iPod - clear, and able to distinguish poorer recordings for sure. Isolation from outside sound is quite good. I haven't played with the adjustment for the bass yet. It should also be pointed out that there are no instructions provided with the unit.
This is my first experience with CIEMs and they are certainly comfortable and not fatiguing as headphones can sometimes be. The cord is somewhat short and I would need the source quite close to me. I'll probably purchase an extension so I can use them at my desk played through an external DAC. I have previously been using older Etymotic Research IEMS (earlier version of the ER-4) and I prefer the new Roxannes although unfortunately I can't use them with my older iPod
I have not had a chance to try them with the MacBook Air yet and don't know if that will cause the same type of hiss. Hopefully it won't, as that will likely be my next laptop and I was hoping to use these with a laptop. Of course, using a USB type DAC with the laptop might alleviate the problem but unfortunately I have no way of knowing that up front.
I did contact JH Audio about the hiss, and they responded that the Roxannes had so much top extension that it was revealing the noise at the source.
Has anyone who has received the Roxannes had any similar experience with background hiss and is that to be expected with laptops for ex.? Does it resolve with an external DAC/Amp? If anyone has any other suggestions for use with the laptop or older iPod that would be appreciated.
That's about all the info I can provide at this time. So far I am very pleased with the sound but hope that I can find a solution so that I can use them with more sources as I don't plan on buying an A&K. Potential users may want to consider what sources they plan on using the Roxannes with. For those who have ordered and are waiting, I can understand your frustration but I think you will enjoy the sound once you ultimately receive them.
