JBL Go 5 Review: The Ultra-Portable Speaker Gets a Significant Upgrade

Introduction: The Return of the Go-To Portable Speaker

In the fiercely competitive world of ultra-portable Bluetooth speakers, JBL’s Go series has consistently offered a compelling blend of compactness, durability, and surprising audio quality. Released in April 2026, the latest iteration, the JBL Go 5, arrives with the ambitious goal of improving upon its highly regarded predecessor, the JBL Go 4. As a senior technology journalist for Veredict, I've put countless portable speakers through their paces, and the Go 5 genuinely stands out as a strong contender for the best cheap Bluetooth speaker available right now. While maintaining its signature grab-and-go appeal, this new model introduces a host of refinements and features designed to elevate your listening experience without breaking the bank. With a modest price tag of $54.95 / £39.99 (approximately AU$75), it represents a slight increase in the US market over the Go 4, but the enhancements justify the value.

Design and Durability: Built for Adventure

At first glance, the JBL Go 5 retains the familiar square-but-rounded aesthetic of its lineage, but closer inspection reveals thoughtful upgrades. Measuring 101 x 77.4 x 43mm and weighing in at 230g, it’s only marginally larger and heavier than the Go 4, a difference barely perceptible in daily use. The integrated loop, a hallmark of the Go series, remains a practical feature, allowing users to easily clip the speaker to a bag or bike, making it an ideal companion for any adventure.

A significant leap forward in durability is the upgrade to an IP68 rating for both dust and water resistance, a step up from the Go 4’s IP67 certification. This means the Go 5 is not only fully submersible in water but also completely impervious to dust, offering peace of mind whether you’re at the beach, by the pool, or caught in an unexpected downpour. JBL further enhances its robust construction by marketing it as drop-resistant, ensuring it can withstand the rigors of an active lifestyle.

A notable aesthetic addition is the new ambient edge lighting. These dual lighting strips, subtly integrated along the top and bottom edges, add a customizable visual element to your music. While currently limited to a single color, users can choose from various lighting patterns via the JBL Portable app, or simply turn them off to conserve battery life. This thoughtful inclusion enhances the mood, especially during evening listening sessions.

Sound Quality: Punching Above Its Weight Class

For a speaker of its diminutive size, the JBL Go 5 delivers a remarkably powerful and refined audio experience. It houses a single 45mm full-range transducer, the same size as found in the Go 4, but with an increased output power of 4.8W RMS, up from 4.2W. This seemingly small bump translates into a more potent and articulate sound, capable of greater volume and a fuller sonic profile, ideal for small gatherings or personal listening.

Many reviews highlight the Go 5’s significant sonic improvement over its predecessor, particularly in its bass response. The speaker offers deeper, cleaner bass and more expressive highs, leading to a more well-rounded and impactful sound. While it won't rattle windows, its ability to reproduce sub-bass with impressive clarity and low-end impact is commendable for such a compact device. The frequency response spans from 100Hz to 19kHz (-6dB). Furthermore, the sound has been tuned by Harman Acoustics, a testament to its audio pedigree. Crucially, the JBL Portable app provides a 7-band customizable EQ, allowing users to fine-tune the sound to their personal preferences, with several presets available, or the option to create a custom profile.

Features and Connectivity: Smart Upgrades

The JBL Go 5 is packed with modern connectivity options and intelligent features. It boasts Bluetooth 6.0, an upgrade from the Go 4's 5.3, ensuring a stable and efficient wireless connection. It supports SBC, AAC, and LC3 codecs, with LC3 offering good sound quality even at lower bitrates.

One of the most innovative new features is AirTouch, which allows for instant stereo pairing by simply tapping two Go 5 speakers together. This makes setting up a wider soundstage incredibly intuitive, eliminating the need to navigate through app menus. For even larger soundscapes, the Go 5 supports Auracast connectivity, enabling you to link multiple compatible JBL speakers together for an immersive experience, a feature shared with newer JBL models like the Flip 7 and Xtreme 5.

Adding to its versatility, the USB-C port now doubles as an audio input, supporting lossless audio playback when connected to a compatible device. This is a premium feature not typically found in speakers of this price point and size, offering a superior wired listening experience. The Go 5 is also compatible with the JBL EasySing Mic Mini, expanding its potential uses beyond just music playback.

Battery Life and Portability: Enduring Companionship

The Go 5 offers improved battery life over its predecessor, providing up to 8 hours of continuous playback on a full charge. For those longer listening sessions, the inclusion of PlayTime Boost can extend this to an impressive 10 hours by slightly reducing bass strength to conserve power. While this might not set new records against larger, more expensive speakers, it's a welcome enhancement for its class and sufficient for an afternoon at the beach or a casual outing. Charging is handled via a USB-C port, taking approximately 3 hours.

Its ultra-compact dimensions and lightweight design mean the Go 5 truly lives up to its name, fitting comfortably in the palm of your hand, a small bag, or even a jacket pocket. It's designed to be an afterthought in terms of carrying, but a pleasant surprise when it comes to delivering sound.

JBL Go 5 vs. JBL Go 4: Is the Upgrade Worth It?

For those considering an upgrade from the JBL Go 4, the Go 5 presents a compelling case, though the decision largely hinges on individual priorities. The Go 5 undeniably wins in terms of overall value for money and technical specifications. It brings noticeable improvements across the board: more powerful and refined audio, better sub-bass response, an upgraded IP68 durability rating, enhanced Bluetooth 6.0 connectivity, and the added visual appeal of ambient lighting. The inclusion of USB-C for lossless audio is another significant advantage.

However, some reviewers note that while the Go 5 offers a clear sonic upgrade, it’s not a “night-and-day” difference at lower to moderate volumes, especially if directly compared side-by-side. If you already own a Go 4 and are satisfied with its performance, the incremental improvements might not warrant an immediate upgrade unless the new features like ambient lighting, AirTouch stereo pairing, or USB-C audio are must-haves for you. Yet, if you’re new to the ultra-portable speaker market or looking to replace an older model, the Go 5 is unequivocally the superior choice, delivering a more complete and refined experience for its price.

Verdict: A Pint-Sized Powerhouse

The JBL Go 5 solidifies its position as a top-tier ultra-portable Bluetooth speaker, proving that great things indeed come in small packages. It’s a remarkable evolution of an already excellent line, packing a more powerful, cleaner sound, enhanced durability with its IP68 rating and drop-proof design, and a suite of smart features like AirTouch and Auracast connectivity. The customizable ambient lighting and lossless USB-C audio are welcome additions that elevate the user experience beyond what’s typically expected at this price point. While its battery life, though improved, might not outlast every competitor, and the single-color lighting might disappoint some, these are minor quibbles in an otherwise outstanding package. If you're seeking a highly portable, rugged, and surprisingly capable speaker that delivers exceptional value, the JBL Go 5 is a spectacular choice, truly the best Go yet.
