Genuine Leather Full Metal Headband Compatible with Sennheiser HD650,HD660 S,HD600,HD6XX,HD58X,HD580,HD565,HD545,HD535 Headphone Replacement Head Beam Band Headset

I'm using this to replace my Sennheiser HD580 headband, which finally snapped after years of use. Finding a genuine replacement at a reasonable price seems impossible, so I grabbed this.The instructions are basically "You're on your own, have fun!"None of the included nuts were small enough to fit inside the headphone housing properly, and I'm not going to drill holes, so I ended up using the bits with the rounded ends facing inwards, then bent the frames so they were smaller than the headphone housing, and clipped the new frames on, so they're held in place by the tension of the metal. I have no idea if that's the "correct" method, but it works. The original frames were held in place by pegs and not bolted, so it should be fine.See attached pic: Smallest bolt -> washer -> frame -> round-ended nut with the rubber gasket stretched around it. You need to REALLY bend the frames. They're very wide out of the box.Edit: After using them for a while, I have no major complaints. They're holding up well. They don't look great, but they're perfectly functional, and around 1/3 the price of genuine replacement parts. They'd be a 5/5 if they came with instructions.

So glad this could save my BRAINWAVZ HM5 (same form factor as NVX XPT100), whose OEM headband only lasts a couple years. The metal is pliable enough to accommodate cups smaller than size listed here, although I did need to provide some washers to size up the bolt diameter. Using for undersized cups makes the hardware a bit tough to install, but the end result is worth it.My only complaint is that the junction that allows the cups to rotate could use some lubrication, which I would expect at this price point. Easy enough to fix on my end
