The Bose SoundLink Flex (Gen 2)
This deal also includes the limited edition Twilight Blue color variant.
The more powerful Bose SoundLink Max
The Bose SoundLink Flex (Gen 2) was launched at $150, which was already a good price for the portable Bluetooth speaker. But today, the price is further slashed by a massive 34% for Amazon Prime Day. Surprisingly, this deal is also valid on my favorite limited edition Twilight Blue color variant.
The Bose SoundLink Flex Bluetooth speaker is back to its all-time low price of $99 with a $50 discount. It is one of the best deals that you can get on a portable speaker this Prime Day. I carry this Bose speaker everywhere -- here's why you should consider spending $99 on it.

Bose SoundLink Flex is great for hikes and picnics
Prakhar Khanna/ZDNET
I primarily use the Bose SoundLink Flex as my room speaker, and carry it to lunchtime picnics in parks. It features the company's PositionIQ tech that can automatically detect its orientation and deliver optimized sound based on whether it's upright, hanging or flat on its back. So, you can hang it or place it flat on its back and yet get pretty good sound.
It comes with support for AAC and AptX audio codecs and Bluetooth 5.3 for connectivity to deliver a no-compromise audio experience. This Bose speaker is IP67 rated for dust and water resistance, making it ideal for hikes and outdoor use. It also has a built-in hook, so you can fasten it to your backpack or hang it on a hook with ease. Lastly, it'll last you 12 hours of playtime, but there are two more portable Bose speakers on sale, which are rated for up to 20 hours of playtime.
Bose's Amazon Prime Day discounts also include price cut on the SoundLink Plus and SoundLink Max Bluetooth speakers. The Plus is its latest launch, which debuted with Bluetooth 5.4 connectivity, a water- and dust-resistant IP67 rating, 20 hours of playtime, and reverse USB-C charging capabilities.It features a new acoustic architecture, with one subwoofer, one tweeter, and four passive radiators.

Bose
If you need even more bass and power on your outings, the Bose SoundLink Max should be your go-to choice. Like the Flex, it offers 20 hours of battery life and IP67 rating. The Max also features Snapdragon Sound by Qualcomm, which offers high-resolution, low-latency audio transmission through Bluetooth when paired with a Snapdragon Sound-enabled smartphone.
All three of these Bose Soundlink speakers float in water in case you accidentally drop them.
The Bose SoundLink Plus was launched at $269 but is down to $229 with a 15% discount. But the deal sweetens if you want to go big. The $399 Bose SoundLink Max is now selling at a $100 discount and is back to its all-time low price of $299. At under $300, this is the best portable Bluetooth speaker to buy if you want your next speaker to push the volume to new heights without the slightest bit of distortion.
