Microphone

The built-in far-field microphones are a regular talking point, supporting voice features and audible command pickup without needing external hardware.

The built-in mic input is a useful bonus and, in the review that tested it directly, its raw input quality held up surprisingly well against a much more expensive external sound device.

The built-in microphone is repeatedly mentioned and tested in several reviews. It enables hands-free calling and voice control, and multiple reviewers treat it as a meaningful advantage over small speakers that omit a mic.

The built-in microphone array is a well-covered feature, with several reviews noting far-field pickup and smart-assistant readiness.

The built-in microphone is repeatedly confirmed as a useful feature for calls, especially compared with some compact speakers that lack it.

Built-in microphones support Alexa features and mute control, and reviewers generally found pickup adequate for normal voice use.

The speaker includes microphones for calls, but the reviews do not go deep on call quality.

Microphone-related functionality is indirect. Reviews describe phone-based voice amplification or PA-style recording, while one says a speakerphone is missing.

Microphone evidence is contradictory. Some reviews say there is no microphone or no call support, while SoundGuys reports a built-in microphone with decent clarity, so the overall support is mixed.

The built-in microphone was removed, a repeated caveat across many reviews.

Microphone support is poor for calls because reviews explicitly state that the Boom Go 3i does not include a built-in microphone or speakerphone.
