I just had an incredible repair experience with Brian at BTG Audio. I had a pair of Etymotic ER-6is and originally just thought a reterm was needed. Brian took the time to reterm them and test them out and notify me that one driver was completely out. He refunded me the repair money and shipped them back to me, only for me to find a spare driver from a family member. I had both pairs shipped back to him and he spliced two pairs together and retermed them with a very high quality jack. Not only is the work beyond my expectations in quality (you can't even see the driver splice) but his shipping time and customer service were unbelievable. He gave me estimates every step of the way and he kept me in the loop during every step from receiving the package, to work being finished, and finally with return shipping.
Great job and highly suggest if you need work done, go with Brian at BTG Audio.
