The Sony ULT Field 5 speaker offers deep bass, easy portability, and a feature you won’t find in every Bluetooth speaker— a vibrant party light that sets the mood wherever you go. Right now, it’s 41% off for Prime Day, and according to price-tracking tools, this is its lowest price ever.
Built for summer adventures, this party-ready speaker offers enhanced bass and up to 25 hours of battery life. The quick charging feature provides up to two hours of playtime off just a ten-minute charge, which is ideal for last-minute plans. It also has a 10-band EQ so you can fine-tune depth, clarity, and balance. While the bass performs well, some reviewers note it can compress at max volume and may not sound equally balanced across all tracks.
The ULT Field 5 is surprisingly deep and bassy with full-range audio and immersive sound, perfect for beach days, bonfires, BBQs, or anywhere you want to bring the party. The 360° party lighting syncs music with vibrant LED lights while the IP67 rating means it’s waterproof, dustproof, and rustproof. It can even float if dropped in water.
An included shoulder strap allows for easy carrying, but it’s still larger than smaller-sized competitors in the portable space, and may not be ideal for long-haul trips like hikes. Still, the Sony ULT Field 5 speaker is a powerhouse that blends solid battery endurance, durability, and punchy sound with an unexpected visual party trick at a steep discount. However, if you’re seeking lightweight gear, you might want to explore smaller models from a brand like JBL.
