I had to send back my 846s due to a defect and was wondering if anyone else had the same issue.
In the right earphone only, I'd get an intermittent buzzing noise. It seemed like a sympathetic vibration and not noise/hum or actual distortion of the signal.
I tried different cables and filters, and reseating the filters to no avail. When it was doing it, I could make it repeat with certain tracks that seemed to have the program material in the right range. Then for no reason it'd stop happening and those same tracks would play clean.
I've been using them for 2 weeks and have REALLY enjoyed them and if they were $500 I'd probably just stick with them and put up with the buzzing. For a grand they should be perfect (at least build-wise).
I called Shure USA and logged the problem and returned them to Amazon today. Sad to see them go and looking forward to getting the replacements hopefully soon. The batch was from the end of November.
I'd seen someone else on Amazon that had the same exact problem, but I don't recall any mention of it here.
I use water to lubricate my triple flange hybrid tip to insert it. The water eventually dries and the seal is tight. I have to peal it out when I want to remove it. Throughout the day, I can eat and do whatever and my earpieces stay firmly in place for hours and hours. However, this past week I've been questioning the stability of the seal of my right side earpiece because (for very brief periods) I thought it sounded out of balance. When it happens, I find myself touching and adjusting it (but it doesn't move). A few times I took it out, re-lubed it, and reset it. I wonder now (after reading the above post) if the right side is showing a new sign of a forthcoming problem. I haven't heard any unusual noise (or buzzing) though. It would be just my luck, (that now that I've found Viper4Android [V4A] and things are sounding better than ever) that a problem would develop. My issue hasn't happen today at all and (knock on wood), I hope it was just an anomaly.
Since installing V4A on my Galaxy S2 phone (it seems strange to note that) the blacks are really black (i.e., the quiet spots in and between tracks are really quiet). The next sound (after the quiet) seems to come out of nowhere. The S2 (with V4A) makes my iPod Touch 5g sound artificial, congested, and quite noticeable lacking extension and sharpness.
