Marshall Kilburn III: Rocking the Portable Speaker Scene with 50+ Hour Battery Life
Get ready to crank up the volume – Marshall has just unleashed the Kilburn III, a portable Bluetooth speaker promising a staggering 50+ hours of playtime. That's more than double the battery life of its predecessor and a serious contender against rivals like Beats and Bang & Olufsen.
The Kilburn III marks a significant upgrade from the Kilburn II, released seven years prior. Beyond the extended battery life, Marshall has also enhanced the speaker's durability with an IP54 rating for water and dust resistance, ensuring it can withstand splashes and dirt. But does it stand up to the hype?

A Nod to the Classics
Marshall has retained the iconic guitar amp aesthetic, complete with tactile control knobs for adjusting volume, bass, and treble. This retro-inspired design, reminiscent of the original Kilburn launched a decade ago, has been a hit with fans. The Kilburn III is available in both Black & Brass and Cream colorways, both exuding a premium feel with a velvet-lined carrying strap.
Sound that Travels
The speaker features Marshall's True Stereophonic sound, ensuring consistent audio quality regardless of your position. The dynamic loudness tech automatically adjusts bass, mids, and treble to maintain a balanced sound, even at high volumes. Early impressions suggest that the Kilburn III delivers a rounded and harmonious sound signature with impressive balance across the frequencies.
Under the Hood
The Kilburn III boasts a wider frequency range, extending down to 45Hz for deeper bass notes. Marshall claims the internal acoustics have been fully re-engineered to take a step up from Kilburn II. The speaker also charges external devices, offers Auracast connectivity and has EQ adjustments via the revamped marshall app.
The Price of Power
These upgrades come at a cost. The Kilburn III retails for $379.99, a significant jump from its predecessor. However, the extended battery life, improved durability, and enhanced sound quality may justify the price for audiophiles and portable music enthusiasts.

The Verdict
The Marshall Kilburn III appears to be a compelling option for those seeking a portable Bluetooth speaker with long battery life and classic styling. Whether it lives up to the hype will depend on real-world testing. The Kilburn III is currently available on Marshall's website and select retailers.
