Critic Reviews

Marshall Stanmore III Review | PCMag

pcmag.com

Marshall's Stanmore III delivers an appealing blend of rich audio with a striking retro design. It isn't an audiophile's dream, limited by its basic codec support and a bare-bones app, but it charms with its vintage guitar amp aesthetics. The speaker's adjustable EQ offers some sound customization, yet its bass isn't earth-shattering, and the app experience leaves much to be desired. While it stands out visually, practical features like waterproofing or voice assistant integration are absent. For the price, it may satisfy style-conscious listeners, but the Sony SRS-XG300 remains the top choice for those prioritizing performance.

Marshall Stanmore III review: Wildly impressive but imperfect Bluetooth speaker | AppleInsider

appleinsider.com

The Marshall Stanmore III Bluetooth speaker charms with its vintage amp design and delivers bold, rich sound. However, its hefty price tag of $379.99 brings expectations that are slightly unmet due to limited app functionality and lack of Wi-Fi connectivity. While it offers satisfying physical controls for EQ adjustments, stereo separation falls short. It shines when paired with a turntable, but as a standalone Bluetooth speaker, alternatives like the HomePod might offer more versatility for everyday use. Overall, a stylish yet imperfect choice for audiophiles who value aesthetics and tactile controls.
