Complete genuine Valve Index AUDIO HEAD STRAP - the strap with BOTH off-ear speakers (left + right BMR drivers) and the rear back clip/cradle, ready to bolt onto your headset.
This is the assembly that has been out of stock at official parts channels for roughly two years - if your strap snapped or your audio died, this is the whole fix in one piece. Pulled from a working Index: both speakers tested with clean audio, strap and tension mechanism fully intact.
Also selling speakers individually and other Index parts (cables, knobs, gaskets) - check my listings, combined shipping available.
From NexRush Tech - VR gear, all fully tested. Smoke-free workspace, ships same or next business day from Breckenridge, CO. 30-day returns. Offers welcome.
