The Fostex T50RP has been out for years and years and in that time just about everyone I know has had a go at some sort of modification or another to this sub-$100 headphone. It is the cheapest planar on the market and a pure joy for the DIY guys from Smeggy and his glorious legendary Thunderpants to the less pricey Zach Mehrbach creation. However it was Dan Clark and the team at MrSpeakers that have really capitalized on the sometimes uncertain “What if we do this?” mantra of the DIY lobby into a class leading standard “Wait until you hear this!” with the Mad Dog last year. Now they are back with possibly the best iteration of the T50RP mod legacy yet in the guise of the Alpha Dogs, the worlds first 3D printed production headphone.
