When it comes to wireless speakers in 2024, the Marshall Stanmore III ($379) and Anker Soundcore Motion X500 ($169) represent two distinct approaches to delivering quality audio. While both are Bluetooth speakers, they serve notably different purposes, and understanding these differences is key to making the right choice for your needs.
Since the Stanmore III's release in late 2022, it has represented Marshall's commitment to premium home audio, building on their legacy of professional sound equipment. The Motion X500, launched in 2023, showcases how far portable speaker technology has come, particularly in terms of spatial audio processing and weather resistance.
Both speakers feature modern Bluetooth implementations - 5.2 in the Stanmore III and 5.3 in the Motion X500. These newer Bluetooth versions bring improved range and stability compared to older 4.x versions, while supporting multiple device connections simultaneously.
The Stanmore III delivers impressive audio quality through its sophisticated driver setup. With 80 watts of total power split between two tweeters (high-frequency speakers) and a dedicated woofer (low-frequency speaker), it creates a wide, room-filling soundstage. The tweeters are intentionally angled outward, helping create a more three-dimensional sound field that's particularly noticeable when watching movies or gaming.
What's especially clever is the Stanmore's Dynamic Loudness feature, which automatically adjusts frequency balance at different volumes. This addresses a common issue where bass and treble can sound weak at lower volumes - a problem known as the Fletcher-Munson effect.
The Motion X500 takes a different approach, using three drivers totaling 40 watts, including an upward-firing speaker that contributes to its spatial audio capabilities. While it can't match the raw power or bass response of the Stanmore III, it produces impressive sound for its size. The inclusion of LDAC codec support (a high-quality Bluetooth audio format) means it can handle higher-resolution audio streams than many portable speakers.
In practical use, the Stanmore III excels in dedicated listening spaces. Its audio quality becomes particularly apparent when playing high-quality audio sources or serving as part of a home theater setup. The physical EQ controls (bass and treble knobs) make it easy to adjust the sound to your room's acoustics.
The Motion X500 shines in versatility. I've found its IPX7 water resistance rating (meaning it can be submerged in 1 meter of water for 30 minutes) makes it genuinely practical for outdoor use. The 12-hour battery life is sufficient for most occasions, though it does drop significantly when using spatial audio features or playing at higher volumes.
The Stanmore III introduces several technical improvements over its predecessor:
The Motion X500 brings some impressive tech to the portable segment:
When considering value, it's important to look beyond just the price difference. The Stanmore III's higher cost includes premium audio components, superior build quality, and the ability to serve as a primary home audio solution. Its wired inputs (RCA and 3.5mm) also add long-term flexibility.
The Motion X500's lower price point delivers impressive features for portable use, including water resistance and battery power, while maintaining good sound quality. It's particularly appealing for users who need a speaker that can move between different environments.
Both speakers offer companion apps for control and customization, though their approaches differ. The Stanmore III's app focuses on essential functions like EQ adjustment and firmware updates, while the Motion X500's app offers more features like lighting control and spatial audio adjustment.
Both speakers are well-positioned for future updates. The Stanmore III's over-the-air firmware updates ensure it can adapt to new Bluetooth improvements, while the Motion X500's modern codec support means it's ready for high-resolution audio streaming.
The Marshall Stanmore III and Anker Soundcore Motion X500 represent different solutions for different needs. While the Stanmore III excels as a premium home audio component, the Motion X500 offers impressive versatility and modern features at a more accessible price point. Your choice should ultimately depend on how you plan to use the speaker and what aspects of audio performance matter most to you.
