Claw SM70

Manufacturer: Claw

The Claw SM70 is a wired over-ear headphone built for straightforward, no-frills listening. It comes with a 4-metre detachable cable that is also tangle-free, making it a practical choice for desktop or studio-style use. A travel bag is included in the box, and the on-device control panel allows basic adjustments without interrupting playback. The headset functionality means it can handle calls as well as audio.

On the technical side, the SM70 covers a frequency range of 18 Hz to 28,000 Hz and operates at an impedance of 32 Ohms, pairing well with standard consumer devices. Its sound pressure level is rated at 97 dB/mW, driven by a 40 mm driver unit. The closed-back design contributes to passive noise reduction, helping to block out ambient sound without any active processing. Connectivity is strictly wired, with no USB Type-C charging or wireless features present.

Pros
  • The detachable and tangle-free cable makes management straightforward and allows for easy replacement if needed
  • A 4-metre cable length provides considerable reach, suitable for desktop or studio-style setups
  • Passive noise reduction helps block ambient sound without requiring any power or electronic processing
  • Can function as a headset, supporting voice communication alongside audio playback
  • A travel bag is included, offering a ready-made storage solution out of the box
  • Controls are placed on the device itself, keeping the cable clean and uncluttered
Cons
  • No active noise cancellation, which limits effectiveness in louder environments
  • Cannot be folded, making the headphones bulkier to pack or store despite the included travel bag
  • No in-line control panel means adjustments must be made directly at the source device
  • Lacks ambient sound mode, so the user cannot let in environmental audio without removing the headphones
  • No in-ear or on-ear detection, meaning playback does not pause automatically when the headphones are removed
  • No water resistance, so use in wet or outdoor conditions carries a risk of damage
Who is this for?

The Claw SM70 is well suited to users who need a reliable desktop or stationary listening setup, where the generous 4-metre wired cable provides ample reach without the need for wireless connectivity. The included travel bag and detachable cable make it a reasonable option for those who occasionally transport their equipment, while the headset capability makes it practical for users who need to handle calls or voice communication alongside standard audio use. Its passive noise reduction also suits those working in moderately noisy environments who prefer a simple, power-free approach to blocking out ambient sound.

Who is this NOT for?

This model is not well suited to users who prioritise portability or on-the-go use, as it cannot be folded and offers no wireless connectivity, making it cumbersome to carry and use away from a fixed setup. Those who need strong isolation in loud environments may find the absence of active noise cancellation a significant drawback. Additionally, users who require convenient playback control without returning to their source device will find the lack of an in-line control panel frustrating, and anyone intending to use the headphones in wet or outdoor conditions should note that there is no water resistance whatsoever.

The Claw SM70 covers a frequency range of 18 Hz to 28,000 Hz and uses a 40 mm driver unit, operating at an impedance of 32 Ohms. Its sound pressure level is rated at 97 dB/mW, providing a measure of its overall output sensitivity. The headphones include passive noise reduction, helping to attenuate ambient sound through physical isolation rather than electronic processing. Active noise cancellation, spatial audio, and a neodymium magnet are not part of this model's feature set.

Power:

Has USB Type-C ✕
Has a solar power battery ✕

The Claw SM70 does not include USB Type-C connectivity or a solar power battery, indicating that this model has no onboard power requirements — consistent with its fully wired, passive design.

Connectivity:

Has an in-line control panel ✕

The Claw SM70 supports headset use, meaning it can handle voice communication in addition to audio playback. Controls are placed directly on the device rather than on an in-line cable panel, keeping the cable itself free of additional hardware. Ambient sound mode, in/on-ear detection, and a dedicated mute function are not included in this model's feature set.

Final Verdict

The Claw SM70 is a no-frills wired over-ear headphone that delivers a straightforward, dependable experience for users anchored to a fixed listening environment. Its 4-metre detachable, tangle-free cable paired with headset functionality and passive noise reduction make it a practical choice for desk-based use where reliability and ease of setup matter more than advanced features. That said, the absence of folding capability, wireless connectivity, and active noise cancellation means it is firmly positioned for stationary rather than mobile use. For anyone seeking a simple, wired headphone with a usable feature set for everyday desktop or communication tasks, the Claw SM70 fulfils its intended purpose without overreaching.
