Razer has launched the new Opus X headphones via its own website. These new wireless accessories have emerged as a new mid-range variant of their series, compared to the original Opus cans. They support active noise cancellation (ANC) and a low-latency connection, yet lack the THX certification of their predecessors, not to mention a 3.5mm port for a wired mode.

Props to Razer for making cheaper products, but their Opus headphones from last year are $100 on eBay new and I'd argue that it is a better deal than these X variants.
Of course, if you don't trust eBay you can find it on Amazon for $130, not too much more than the Opus X.
Don't regret jumping for the Opus for $130. They're quite amazing.
