You can always find some good Bluetooth speakers among the best Amazon Prime Day deals, and this year's Big Deals Day event has brought us a bunch of record-low prices on options from big names. I've picked out the options that I think offer the best value, based on our reviews of the products and experience with the brands.

This time around there are some great Bose deals, with savings on the likes of the QuietComfort Ultra headphones, the SoundLink Max Bluetooth speaker, and even newer products like the Ultra Open Earbuds. There are savings of up to $130 off, so you'll save money no matter what Bose product you want.

Finding half-off deals on quality tech products, from home security cams to robot vacuum cleaners, is difficult but not impossible, especially during Prime Big Deal Days.
