Third-party reviews

Based on ratings from across the web.
Reviews last updated: August 2026 · How we calculate this

What customers like about Astell Kern Acro BE100

  • Excellent sound quality with clear vocals and highly detailed instrumentation
  • Sophisticated, premium design featuring a grain-leather pattern and a unique angular aesthetic
  • Outstanding Bluetooth codec support including high-resolution LDAC and aptX HD
  • Dedicated 32-bit Hi-Fi digital-to-analog converter (DAC) that prevents audio distortion
  • Onboard physical five-level treble and bass EQ adjustment settings

What customers don't like about Astell Kern Acro BE100

  • High price point compared to competitor wireless speakers
  • Lacks portability due to having no built-in rechargeable battery power
  • Absence of a dedicated smartphone companion app or advanced smart features
  • No Wi-Fi connectivity or multi-room ecosystem capabilities
  • Soundstage loses bass depth at high volumes and lacks true stereo separation due to its compact size

Verdict

The Astell&Kern ACRO BE100 is a premium home Bluetooth 5.0 speaker designed for audiophiles, featuring a dedicated 32-bit Hi-Fi DAC, a custom 4-inch Kevlar woofer, two 1.5-inch silk dome tweeters, and an in-house Class-D amplifier delivering 55W of total output power. It excels with high-resolution wireless playback by supporting 24-bit aptX HD and LDAC codecs, alongside physical connectivity via a 3.5mm AUX input and manual five-level onboard bass and treble adjustments. Main advantages include exceptional sonic clarity, punchy low-end response, low-distortion audio output, and a striking angular architectural chassis with a premium knurled volume knob. However, despite being mistaken for a portable device, it lacks an internal battery and requires a constant wall outlet connection, lacks a dedicated mobile companion app for advanced equalization, and offers no Wi-Fi or digital assistant integration.
