October Prime Day sales have slashed the prices of many, but given that you're spoiled for choice, it can be difficult to determine which you should buy.Lucky for you, I've sifted through hundreds of deals to find the ones that are actually worth your money. I test Bluetooth speakers for a living, and I've either personally reviewed or at least spent a good chunk of time listening to the following speakers.My favorite deal is on the JBL Go 5 which is currently down to its lowest ever price of just $39. I awarded it 4.5-stars in my JBL Go 5 review, and it's a tiny yet powerful speaker for taking on the go. If you want a bigger and classier-looking speaker, the Marshall Emberton III is 44% off right now, and at that price, even I'm tempted to buy it.Here are the seven best Bluetooth speaker deals I've found this October Prime Day, starting at just $27!Quick linksShop all October Prime Day sales nowTribit StormBox Mini+: was $39 now $27JBL Go 5: was $54 now $398BitDo Retro Cube 2: was $49 now $39Tribit StormBox Micro 3: was $64 now $47Marshall Emberton III: was $179 now $99Bose SoundLink Flex (2nd Gen): was $159 now $99Marshall Bromley 450: was $799 now $599Best October Prime Day speaker dealsshop all October Prime day dealsYETI sale: deals from $10Amazon devices: deals from $12Anker Smart Display Charger: was $39 now $23Skechers: from $25TV sale: deals from $69 (Image credit: Future)Follow Tom's Guide on Google News and add us as a preferred source to get our up-to-date news, analysis, and reviews in your feeds.
