Listen loud and clear
The technology in the ULT FIELD 5 works in harmony for better sound quality. The X-Balanced Speaker Unit delivers deep, punchy bass, and clear vocals even at high volumes. Tweeters provide crisp and spacious sound for high-frequencies. And the passive radiators are optimized to enhance bass sound. Put it all together and you get a great sound worth sharing with your friends.
Powerful sound with X-Balanced Speaker Unit
Our X-Balanced Speaker Unit features a non-circular diaphragm, for an increased surface area compared to conventional speaker units. The approx. 79mm x 107mm large woofer unit is designed for clear and deep bass sound.
A richer, clearer, deeper experience
The non-circular diaphragm not only maximizes the area of speaker diaphragm but it also increases sound pressure for deeper and punchier bass, less distortion and greater vocal clarity. Altogether, it elevates your listening experience.
Sound Field Optimization
By detecting ambient noise, sound settings can be automatically tuned to deliver clear sound even in noisy or outdoor environments.

Value for Money
81/100
Warm, lively sound and a wide, balanced presentation define this rugged portable speaker, with crisp treble, clear vocals and party-ready LEDs adding extra appeal. Sound Advice notes that the bass can feel light unless boosted, while Best of High End highlights its fun, concert-style character and outdoor-friendly design.
What Reviewers Are Saying
Pros
Warm, balanced tuning with clear vocals and a bright, detailed top end.
Wide soundstage and lively presentation that suits upbeat music well.
Rugged IP67 build, 25-hour battery life and useful multi-point pairing.
Party-friendly extras like LED lighting and Sony speaker pairing boost its appeal.
&
Cons
Bass can sound light, hollow or lacking depth, even with the ULT boost modes engaged.
Its 3.3kg weight and bulky shape make it less convenient to carry than many rivals.
The shoulder strap is described as fiddly, which weakens its portability.
SOUND QUALITY PERFORMANCE 81/100
Reviewers describe a warm, rich and generally balanced presentation, with clear vocals and a lively character. The main weakness is in the low end, which is repeatedly described as lacking depth, punch and fullness unless the bass-boost mode is used, and even then the result can lose clarity.
Bass
72/100
The bass is the clearest weak spot. One review says the lower frequencies lack punch, depth and richness and can sound hollow or flat, although another notes the bass line can be powerful without becoming distorted. The extra bass mode adds weight, but it does not fully solve the sense that the low end is not especially well rounded.
Mid
85/100
The midrange is described as natural, clear, warm and full, with vocals benefiting from a consistent presentation. The main caveat is that the ULT mode can push the lower frequencies forward enough to obscure vocals and reduce clarity and detail.
Treble
86/100
The top end is praised for being crisp, bright and free from harshness, with plenty of detail and a fresh, vibrant quality on electronic material. Reviewers do not report obvious sibilance or glare, though the language suggests an energetic rather than especially silky treble balance.
Soundstage Imaging
82/100
The soundstage is described as fairly wide, with enough room for instruments and vocals, and the speaker can create a lively, lush spread when positioned horizontally. Still, small details can get lost in the mix at times, and the presentation sounds less expansive in vertical orientation.
Dynamics
79/100
The speaker sounds lively and can handle bass-heavy material without obvious distortion, even with the ULT mode engaged. Beyond that, the reviews say little about large-scale dynamic contrast or impact, so the sense of drive is positive but not especially well documented.
Assessments of Build Quality, Usability, and Overall Propositions.
Build Quality
83/100
Reviewers describe a durable, IP67-rated portable speaker with a solid feature set and a practical, rugged design. The main reservation is physical convenience: it is bulky for a portable model, weighs 3.3kg, and the shoulder strap is said to be fiddly rather than genuinely user-friendly.
Value for Money
81/100
At £259, the speaker is described as not cheap in a crowded portable Bluetooth market. Reviewers see it as a solid buy if you want ruggedness, bright sound, long battery life and party-friendly extras, but the price and competition keep it from feeling like a standout bargain.
