Apple's AirPods and AirPods Pro haven't been this cheap since Cyber Monday 2020
Hence, you can probably understand why Amazon might feel the need to try to sweeten the AirPods Pro deal, shaving an extra 10 bucks off the aforementioned list price at checkout on top of the "normal" $49.01 discount instantly offered on and off for the past few months.
The non-Pro Apple H1-powered AirPods with a non-wireless charging case bundled in are similarly listed at $39.01 off their regular $159 price at the time of this writing while also qualifying for an additional $10 savings at checkout. Compared to their fancier siblings, these affordable puppies can actually keep your favorite tunes going longer on a single charge, so despite the missing active noise cancelling functionality, you shouldn't completely disregard this variant.
What you should do is make your choice as soon as possible and pull the trigger before Amazon inevitably puts an end to the $10 extra promos or these combined deals altogether. By the way, the non-Pro AirPods are also sold at a straightforward $39.02 (20 percent) discount with a wireless charging case included and no need to wait for anything to happen while checking out and completing your order.
You could also get the wireless charging case by itself to use alongside an entry-level pair of first or second-gen AirPods, although Amazon isn't exactly offering a huge discount right now, selling the accessory for $10 less than its usual price of $79.
