Best Prime Day Amazon Deals

Prime Day is here, and with it come some of the best Prime Day Deals Amazon has ever offered–including a greatly reduced price on the Ultimate Ears Boom 3. The price has been cut from $150 down to just $80 for a truly impressive little Bluetooth speaker.

The Ultimate Ears Boom 3 gives truly impressive 360-degree audio and up to 15 hours of battery life on a single charge. It’s the perfect companion for tailgating or afternoons spent at the park. If you feel like 15 hours isn’t enough — or you won’t be able to charge it on the go — you can add the Power Up charging dock to the device so that it is always ready to pump out your favorite tunes, no matter where you might be.

The Ultimate Ears Boom 3 has an IP67 rating, which means it can withstand exposure to both water and dust. Take it in the shower with you if you want; a splash or two won’t hurt it. You can use the all-new Magic Button to play, pause, skip, and control any stream directly from the speaker itself. Enjoy your own custom playlists for Spotify on Android. You can also pair multiple speakers together to create your own surround sound experience at home or on the go.

This deal is on the special Amazon-only Dusk color, a black and metallic red combination that will look great no matter where you set the speaker up. Toss it in the pool or inside the dugout. No matter the environment, this speaker will bring the music and keep you pumped and motivated to play your hardest.

This is a great deal for music lovers. If you’re looking for the perfect gift for that friend that is always on the go and always seems to be the life of the party, it’s hard to beat this Bluetooth speaker. The deal is limited, though, so don’t wait — it will sell out quickly. Combine this with other Prime Day Bluetooth speaker deals and you can create the ultimate audio experience without any wires at all.

Every week, the AI music problem is getting increasingly hard to ignore, especially for streaming platforms. Deezer reported that 44% of all new music uploaded to its platform daily is now AI-generated; that's almost half the songs.

Spotify relabeled and tightened its AI policies last September, while Apple Music announced a tagging approach in March. However, the subscription-based artist-first music platform Tidal has done something none of them did.

Netflix just got a whole lot more irritating if you share a screen in a household
Every profile will soon need its own email address, adding another hurdle for households that share a TV.

Netflix's password-sharing crackdown isn't over just yet. The streaming giant is now rolling out another change that could make shared household accounts a little more cumbersome, this time by asking every profile on an account to have its own email address. While the move isn't designed to stop families from sharing a subscription, it does add another layer of identity verification that many users probably weren't asking for.
