En bref, on en a pour 22€. I used 5/16" bolts to mount the wooden plaque with the wall TV mount bolted to the plaque to the GS Power Tube Clamp Brackets, I bought a size to large so I used Gorilla tape on the pole to make the brackets clamp down tight onto the pole. Did not keep them. Worked much better than other racks because the holes matched up with studs in the wall. This little sucker was a pain to put together but once it was all screwed in it looks nice. I like my clothes fitting tight but this was WAY too tight. I highly recommend this for your Index. You get superior sound quality using external mic through this jac while recording or doing youtube/facebook live from your laptop. I’d say if you have any inclination to get the Philips X2HR’s and you appreciate a ‘truer’ headphone (yet with generous bass) get the A990Z’s (though personally I’d go another step and get the more immediate MT5’s), on the other hand, if you like a full, open, fruity, forgiving sound, the X2HR’s are a good choice. I couldnt go back.
