CMF BY NOTHING Speaker M E495 Portable Bluetooth Speaker, 35W

The CMF BY NOTHING Speaker M E495 is a portable Bluetooth speaker with a claimed 35W output, dual drivers and a built-in carry handle. Its advertised 18-hour playback figure applies at under 50% volume, making it more suitable for moderate-volume listening than as a guaranteed all-day runtime at louder levels.

At a glance

The manufacturer describes a 25W woofer and 10W tweeter, with 35W RMS output and a 60Hz–20kHz range.
Advertised battery life is up to 18 hours, with the feature claim specifying under 50% volume. A separate manufacturer detail lists frequency response as 20 KHz, so the range claims are inconsistent.
IP68 dust and water protection is claimed, including submersion up to 1.5m for up to 30 minutes.
Bluetooth 6.0, NFC Fast Pair, USB-C audio and dual-device connection are described in the feature text.
A built-in handle, removable front panels, sound presets and custom EQ are described by the manufacturer.

Pros and cons

Pros

The stated 35W RMS output is split between woofer and tweeter drivers, rather than relying on a single driver.
The claimed IP68 rating and built-in handle suit portable use around outdoor settings, subject to the stated protection limits.
USB-C audio is claimed to support lossless digital audio with latency below 60ms, a useful option for desktop video and gaming.
The listing describes stereo pairing with a second Speaker M and Auracast Party Mode with compatible speakers.

Cons

The 18-hour playback claim is conditional on listening below 50% volume, so it does not establish runtime at higher levels.
Stereo pairing requires a second Speaker M, while Auracast Party Mode requires compatible additional speakers.

What to know before buying

Listing details to confirm

The listing's technical details give frequency response as 20 KHz, while feature text specifies 60Hz–20kHz. It also lists generic Bluetooth, NFC and USB connectivity and touch controls, whereas feature text specifies Bluetooth 6.0, USB-C audio and a physical knob with dedicated buttons. The listing claims IP68 protection but its general waterproof field provides no rating. Check the selected product details for the connection, control and protection specifications that apply.

The supplied evidence contains aggregate ratings but no written customer feedback. The small rating sample is mixed, so it offers limited guidance about real-world sound, battery life or durability. Consider the manufacturer's stated 35W output and the volume condition on its 18-hour battery claim, but do not treat those specifications as customer-confirmed performance.

Frequently asked questions

How long does the Speaker M battery last?

The manufacturer advertises up to 18 hours, with the feature claim specifying continuous playback below 50% volume. A separate listing section says around three hours for a full recharge.

Is the Speaker M waterproof?

The manufacturer claims IP68 dust and water protection, including submersion up to 1.5m for up to 30 minutes. Follow the product instructions and do not treat the listing claim as independently verified.

Can this speaker provide stereo sound?

The listing describes stereo output and says two Speaker M units can be paired in Stereo Mode. A second speaker is needed for that paired setup.

What connections does it support?

The details list Bluetooth, NFC and USB. Feature text further specifies Bluetooth 6.0, NFC Fast Pair and USB-C audio, but the listing does not consistently describe the connection details, so confirm the selected configuration.
