Sony’s Best Mid-Range Portable Speaker Is Now $150 Off.
Sony is well known for its excellent headphones , but it also makes excellent speakers . One of its latest rugged portable speakers is the ULT Field 5 , which was released in spring 2025 alongside the ULT Field 3 and ULT Tower 9. This speaker sits between the ULT Field 3 and ULT Field 7 in price and features, offering the perfect balance of portability and power.
It’s my pick for the best midrange speaker released last year , and you can now get it for $198 , more than 40% off its original price of $349.99—a near-record low for this model, according to price tracking tools .
The ULT Field 5 is a portable speaker with powerful bass, a great option for those who value long battery life and portability, as noted in a “great” PCMag review . It features a ten-band equalizer, a true woofer (surprising given its compact size), a bass-boosting ULT mode, an IP67 rating (meaning waterproof, dustproof, shockproof, and corrosion-resistant), and the ability to connect to other speakers via Party Connect.
With ULT Power mode enabled, you can expect 25 hours of battery life. However, when playing at full volume, the battery drains much faster, providing about five hours of playtime. A quick 10-minute charge provides two hours of listening time, a nice bonus for a portable speaker. It uses the Sound Connect app, where you can monitor battery level, control the equalizer, connect to other Sony devices, and use the DJ Control feature, which lets you add sound effects to your music.
This speaker is designed for parties, outdoor use, and large spaces. It comes with a shoulder strap that can be attached to the speaker for easy portability.
