The Ultimate Ears Miniroll, a palm-sized clip-on Bluetooth speaker, is down to $47.49 on Amazon for October Prime Day.
Amazon cut the Miniroll's price from its $79.99 list down to $47.49, which price trackers say is the lowest it has ever sold for. The puck-shaped speaker weighs just over half a pound and comes with a removable rubber strap for clipping onto a backpack, bike handlebar, or shower caddy. It runs about 12 hours per charge over USB-C, carries an IP67 rating against dust and brief dunks, and has a 40-meter Bluetooth range, so you can leave your phone inside while it plays on the patio. PCMag's review found it gets louder than its size suggests, though bass-heavy genres like hip-hop and electronic music sound thinner, and pushing past roughly 80% volume blurs the sound and makes the speaker vibrate.
This is a budget speaker, and Ultimate Ears isn't pretending otherwise. There's no companion app, which means no equalizer, no codec switching, and no find-my-speaker feature - what ships in the box is permanent. The appeal here is portability and price, not audio fidelity, and that's a fair trade for a speaker meant to live on a bike or in a shower caddy rather than a living room.
Do the math: $79.99 minus $47.49 is a $32.50 discount, not the flat $30 some sale banners round to - still the cheapest this speaker has ever been, in a category of clip-on speakers that live and die on how many corners they cut for the price.
