Third-party reviews

What customers like about Monitor Audio Airstream S300

  • Excellent, high-end sound quality with 140W to 150W of powerful room-filling output.
  • Premium build materials utilizing high-end mineral-filled polymer and toughened glass end trims.
  • Compact and space-saving design that fits easily on small shelves, tables, or can be wall-mounted.
  • Features Automatic Position Correction (APC) with an integrated microphone to optimize sound balance for room acoustics.
  • Supports multiple wireless streaming methods including Apple AirPlay and point-to-point AirPlay Direct.
  • Versatile physical connections featuring a 3.5mm auxiliary input for use as a TV soundbar and a USB port for device charging.
  • Includes a convenient physical on-device control panel and an infrared remote control.

What customers don't like about Monitor Audio Airstream S300

  • Severe lack of wireless compatibility with Android or Windows mobile devices, limiting non-iOS users to wired 3.5mm playback.
  • Lacks native Bluetooth connectivity, relying strictly on Wi-Fi or point-to-point AirPlay networks.
  • AirPlay Direct mode restricts day-to-day use by only allowing playback of locally stored or offline files.
  • Unconventional curvy aesthetics that may not appeal to all classic speaker design preferences.
  • Higher power consumption when in active use compared to smaller standard portable wireless speakers.
  • Relatively large physical footprint and heavier weight that restricts spontaneous on-the-go portability.

Verdict

The Monitor Audio Airstream S300 is a powerful wireless home audio system delivering 140W RMS of power through a 2-way configuration consisting of two 4-inch C-CAM bass drivers and two 1-inch C-CAM gold dome tweeters powered by four Class D amplifiers. Key technical characteristics include a frequency response of 55Hz to 30kHz, a 104dB maximum SPL, an integrated 24-bit DAC, and a specialized Automatic Position Correction (APC) room calibration system. Main pros are its expansive, room-filling soundfield with high-resolution digital clarity, router-free streaming via point-to-point Airstream Direct, and convenient physical inputs including a 3.5mm auxiliary port and a USB charging port. However, major cons include a lack of built-in Bluetooth or DLNA certification, strict reliance on Apple AirPlay for standard wireless streaming, and format limitations restricted primarily to AAC, ALAC, and MP3.
