Just wanted to share my shorty balanced cable + 177X GO + ES100 BT rig. I can't find a thread for the Massdrop Beyerdynamic DT 177X GO. Did we really neglect to make a thread here?? In case you don't know about them, Massdrop did a collab with Beyerdynamic and in my mind it really filled an open slot in the closed back headphone world. Technically competent, very fun and enjoyable with included sheepskin pads (also comes with stock velour). More bass with the sheepskin pads, switch to velour or Brainwavs pleather perforated for more treble/less bass in tilt. Modified the original DT 1770 PRO design: Impedance lowered from 250 ohm to 32 ohm for use with more devices Sound signature has additional damping to specifically do two things: lower the upper mids peak similar to Amiron Home for a less-piercing presentation, smooth the bass to lower mids transition (still a lot of bass but the dip to make it even more punchy is removed so it sounds more linear) New cable connector at the cup to allow for custom mini-4-pin XLR balanced cables to be made All of those changes make this headphone more transportable to be sure...and even portable? Hart Audio Cables ended up making two very well-built and reasonably-priced custom balanced cables for me. 1. 7.5" of cable in between the plugs works, but is a bit tight for clipping the ES100 BT puck to the frame horizontally. 2. 9" of cable between the plugs is perfect for a relaxed fit that does not bug my shoulder like I thought it might. Note: that is a right angle TRRS 2.5mm balanced plug on the cable and mini-4 pin XLR female plug at the cup end. Voila: I run the ES100 with the Earstudio app in 2x Voltage Balanced mode. Very happy with this "wireless" headphone: Just in time for mulling about the house a lot.
