They arrived really fast. Its a big help to see my phone when I ride. I picked these up and just wow! In an attempt to locate the transformer saturation level I ran the output level up to 80 watts; that was all my test amp and dummy load could handle. Great, comfy! The deadzone is huge when this isnt set up properly. 5 but after reading the reviews I ordered a half size up and they fit perfect. I had high hopes for an all in one headset to use on and off when I dont feel like using my Sens and boom mic but even after a break in there is no way these are going to develop more highs. Ive bought this style Birkenstock before and it works for me, but this is the first soft-sole Ive tried and I thought it would be a bit cushier. Our usual spot is in the mountains above 10,000 feet, so the weather can be very unpredictable.
