Finding especially good deals on Amazon Prime Day can be challenging (trust me, I do it nonstop for our coverage), but the discount on the Bose SoundLink Flex is a standout one. For now, you can get the portable Bluetooth speaker in select colors for $99 ($50 off) at Amazon and direct from Bose or for $99.99 at Best Buy. Amazon gates the deal behind its Prime membership paywall, but anyone can buy from the other two retailers.

This is the lowest price to date on the SoundLink Flex, which is our top pick of Bluetooth speakers under $200. Bose’s colorful speaker has a small footprint, making it easy to throw in a bag and travel with, but it sounds like a much larger speaker. It’s got a nice, bass-rich sound that doesn’t cross into “that’s too much bass why are you rattling my skull” territory. And its IP67 water and dust resistance and 12-hour battery life means it can head for the great outdoors or pool and keep the tunes going for most of the day.

It’s an easy recommendation at this price if you’re in the market for a Bluetooth speaker, care about sound quality, and don’t want to spend a whole lot more to get something like a Sonos Move 2.

Other notable speaker deals for Prime Day

The Bose may be one of the best bang-for-your-buck speaker deals going on this Prime Day, but there are a variety of others that are worthy of consideration — both in the Bluetooth world and even in the entertainment sphere with soundbars.

The Sonos Roam 2, which came out less than two months ago, is selling for $143 ($36 off) at Amazon and direct from Sonos. The retro-styled JBL Authentics 300 is $100 off at Amazon, Best Buy, and B&H Photo, and is currently selling for $349.95. Another JBL, the pocketable Go 3 is $31.53 ($18 off) at Amazon in various colors. And the Ultimate Ears Wonderboom 3 is another alternative that’s $56.99 ($44 off) at Amazon in its unique pink, blue, and gray color combos.

And yes, for just you Vergecast listeners, there are even discounts on some of Sony’s new ULT party speakers. The Sony ULT Field 7 Bluetooth party speaker is $398 ($101 off) at Amazon. The hourglass-shaped speaker is almost boombox-like in its size and has a claimed battery life of up to 30 hours.

But if 45 watts of output from a 14-pound speaker isn’t enough, the Sony ULT Tower 10 weighs in at 64 pounds, pumps out 1,000 watts, and is selling for $998 ($200 off) at Amazon. Both of these ULTs are matching their all-time low prices and feature the coveted “ULT button” and colorful party lights. The Tower 10 even comes with a wireless karaoke mic (and it’s possible your local police will be pre-filing the noise complaints).

Over in soundbar land, the Sonos Ray and Amazon Fire TV Soundbar offer some fairly affordable options at $199 ($80 off) and $99.99 ($20 off), respectively. The Ray has been discounted since the beginning of Prime Day, but unfortunately, Amazon’s combination soundbar and Fire TV streamer was first selling for a lower $89.99. It’s still a decent value at $100 if you want just one box for both audio duties and to stream the content to your TV — but we want you to know it’s sadly no longer the better deal it was.

And lastly, if you want soundbars with multichannel surround setups and big subwoofers, we’ve pulled together a pair of Vizio deals. The Vizio M-Series M512a-H6 is selling for $349.99 ($150 off), while the Vizio Elevate is a pricier $549.99 ($250 off). Both of these setups are 5.1 surrounds with Dolby Atmos support and separate subwoofers. The Elevate’s trick is that it points its side speakers upward for better coverage, and it has a larger eight-inch woofer.
