Are there any alternatives?

Yes, but not any that balance comfort, sound quality, and battery life in quite the same way. For battery life, in particular, the Cloud Alpha Wireless is in a league of its own.

　　$150 Steelseries Arctis 7 — Great sound quality and $50 cheaper, though not quite as comfortable and with much worse battery life.$150 HyperX Cloud II Wireless — HyperX’s own Cloud II Wireless is $50 cheaper at list price and as much as $100 cheaper used, while still offering similar comfort and sound quality. It tops out at 30 hours of battery life, though.

How long will it last?

HyperX sells replacement ear cushions, cables, and microphones, so the Cloud Alpha Wireless could last you 10 years or even more. HyperX has essentially re-released variations of this design for years, and they always hold up. That speaks to the longevity of the Cloud Alpha Wireless.

　　

Should you buy it?

Yes, no question. Unless you need RGB or the fancy trimmings of more premium headsets, the HyperX Cloud Alpha Wireless is the best wireless gaming headset you can buy.
