Sound Devices warns that the headphone output of their SD 702 recorder can damage hearing. For some reason, they designed that output so hot that just barely nudging the volume knob from the zero position results in full normal listening level with my Beyerdynamic headphones. These have a sensitivity of 102 dB for 1mW, only a bit more than typical.
So I looked for a decently-made plug-and-play inline headphone attenuator. This Ear Buddy seemed tailor-made for the job. Received it, tried it out: perfect. Normal listening level is now at least 1/3 turn up, and plenty of headroom remains should conditions warrant. The sound seems unaffected but the benefit of a wide range of subtle adjustments to the listening level is definitely a winner.
While the Ear Buddy appears well-made with good materials, my impression is it’s not designed for harsh conditions or abuse. The right-angle jack is OK although I would have preferred a straight-line jack in my application.
