CMF BY NOTHING Speaker M is a portable Bluetooth speaker with a claimed 35-watt dual-driver output, USB-C audio, and a built-in carry handle. Its battery and IP68 protection claims suit listening away from a desk, while its size and weight are worth considering for frequent carrying.

## At a glance

- The listing describes a 25W woofer and 10W tweeter for 35W RMS output, with a stated 60Hz–20kHz range.
- Manufacturer claims up to 18 hours of playback at under 50% volume and IP68 dust and water resistance, including submersion up to 1.5m for up to 30 minutes.
- USB-C audio is described as lossless with latency below 60ms for desktop gaming and movies.
- The listing describes stereo pairing with a second Speaker M and Auracast Party Mode with compatible speakers.
- A built-in handle, physical controls and removable panels are described. Nothing X app sound presets and custom EQ are also listed.

## Pros

- Claimed dual-driver design separates woofer and tweeter duties, and the listing specifies 35W RMS output.
- USB-C audio and stated sub-60ms latency offer a wired desktop listening option for gaming and video.
- The claimed 18-hour playback and IP68 rating support longer sessions and outdoor use when used within the stated conditions.
- A built-in handle and physical playback controls can make carrying and adjusting the speaker more convenient.

## Cons

- At 602 g, it is heavier than an ultra-compact speaker for buyers prioritizing the lightest carry option.
- Creating left-right stereo mode requires a second Speaker M, and Auracast Party Mode requires compatible speakers.

## Before you buy

- The listing gives 20 KHz as the frequency response in its specifications, but feature copy states 60Hz–20kHz. It also lists latency as 60 milliseconds while describing USB-C latency as below 60ms. Treat these as inconsistent listing details, not settled measurements. The 18-hour playback claim is conditional on under 50% volume.

## In the box

- Safety information (Included)
- Warranty information and User Guide × 1 (Included)
- Speaker × 1 (Included)

## A good fit for

- Listeners wanting a portable speaker with listed battery power, a carry handle and dust and water protection claims.
- Desktop users who want USB-C audio and the listing's low-latency gaming and movie use case.
- Buyers interested in app-based EQ, physical controls or expanding playback with compatible speakers.

## Less suited to

- Anyone seeking stereo left-right separation from a single speaker, since the listing describes stereo mode as pairing two units.
- Buyers who need a verified frequency-response or latency figure before purchase, given inconsistent listing wording.

## Customer feedback

The supplied evidence contains aggregate ratings but no customer-comment summary. The rating distribution leans positive, while a smaller one-star share shows that experiences are not uniformly favorable. With a limited rating sample and no comment details, it cannot establish why customers rated it as they did or how it performs in specific situations.

## Frequently asked questions

### Does the Speaker M provide stereo sound by itself?
The listing identifies stereo output and two audio channels, but describes left-right Stereo Mode as pairing two Speaker M units. Do not assume one unit provides separated left and right channels.
### How long can it play on battery?
The manufacturer claims up to 18 hours, with one feature statement specifying playback at under 50% volume. Actual use may differ, and the claim should not be treated as unconditional.
### Can it be used outdoors or near water?
The listing claims IP68 dust and water resistance and says it is designed for submersion up to 1.5m for up to 30 minutes. Follow product guidance and do not treat this as a guarantee for every situation.
### Is USB-C useful for gaming or movies?
The listing describes USB-C audio as lossless and below 60ms latency for desktop gaming and movies, while the specification table gives 60 milliseconds. The exact latency is therefore not consistently stated.
