Choosing Between Sony's New ULT FIELD 1 and Marshall's Classic Stockwell II: A Complete Comparison

The Evolution of Portable Bluetooth Speakers

The portable speaker market has seen remarkable advances in recent years, with manufacturers pushing the boundaries of what's possible in compact audio devices. When comparing the brand new Sony ULT FIELD 1 ($89.99) against the established Marshall Stockwell II ($149.00), we're looking at two different approaches to solving the portable audio challenge.

Released in April 2024, the ULT FIELD 1 represents Sony's latest tech, while the Stockwell II, launched in 2019, showcases Marshall's time-tested audio expertise. This five-year gap has brought interesting technological advances, particularly in battery efficiency and waterproofing.

Sound Quality Deep Dive

Bass Response and Overall Character

The Sony ULT FIELD 1 introduces ULT POWER SOUND technology, which uses digital signal processing (DSP) to enhance bass frequencies. In practice, this works surprisingly well for a speaker this size, though it's most noticeable in controlled environments. The bass boost function makes a real difference when listening to genres like hip-hop or electronic music, though it can't defy the physics of its compact size.

The Marshall Stockwell II takes a more traditional approach, using larger drivers and a bass-reflex cabinet design. This provides naturally fuller bass without heavy processing. The sound signature is more balanced and natural, which audio purists might prefer. Its dual tweeters and dedicated woofer create a more expansive soundstage.

Volume and Clarity

Both speakers handle moderate volumes well, but their characters diverge at higher levels:

• The Sony maintains clarity but starts to compress at about 80% volume
• The Marshall stays composed even at maximum volume, with less dynamic compression
• Both speakers implement different forms of digital limiting to prevent distortion

Sound Dispersion

Marshall's True Stereophonic technology creates a wider sound field than Sony's single-direction design. This makes the Stockwell II more suitable for group listening situations, while the ULT FIELD 1 performs best when pointed directly at listeners.

Build Quality and Durability

The durability difference between these speakers is significant and might be decisive for many buyers:

Water and Dust Protection
