HANDS DOWN MONSTER CABLE!!!
I know that everyone on here hates on them, but they are truly great in my personal opinion. The first time I called them I was on hold for over an hour and got little to no help, but after that I called in the following day and was connected with Nate who eventually gave me his direct line along with his managers. Nate sent me out a free Control-Talk cord for my Beats by Dre Studios free of charge ($40 value). I have had two pairs of Tours crap out on me within the hour and was upgraded to the Studios for a reduced price. The Studios I got had a minor aesthetic defect in the finish and I was promptly sent out a new pair as soon as I provided them the tracking number.
On top of having one of the manager's direct line (he has always responded to me within the day, which is impressive), SoundMatter12 (I marketing rep for Monster Cable I think?) sent me out a free pair of the TBP Gold's today for all my troubles. I can't wait to see how they compare to my collection of IEM's. (IE8, Hippo VB, Westone 3 (SOON), TBP Tributes, Turbines, and SE530's). They are hands down the best to deal with in terms of customer service in my opinion, I am always left with a feeling of them going above and beyond every other company. Sennheiser takes days to get ahold of someone for technical help, Westone took over three days to get back to me, and Shure was of little help. Out of them all Monster Cable is in first by far, and Sennheiser would be my second favorite mainly because when they finally did get back to me they were extremely helpful. Westone was very helpful it was just hard to get ahold of them at first and neither Sennheiser or Westone would send me out a free pair just for my troubles. Like are you kidding me? That is outrageous and they have won my support for years to come. Everyone stop hating, this is their first shot at making IEM/OEM's and they have done a great job, much more than the majority of people on here are giving them credit for. All their TBP models are phenomenal from what I have read and experienced, and the Studios may be somewhat overpriced but they are the BY FAR the sexiest OEM ever made. They sound incredible, I am more of a bass-head, but I have tried out other OEM's and these completely suited my sound signature requirements. Go Monster!!!
