Bluetooth can be used alongside Aware, and the listing identifies phone calls and radio communication as uses.
The page describes physical noise isolation from the earmuff and foam cushions, rather than electronic active noise cancellation.

Customer feedback highlights Bluetooth connectivity and adjustability positively, while reports on sound quality and noise reduction are mixed. Battery life and comfort also draw varied responses, and value receives criticism. For work use, that variation matters because communication and a secure, comfortable fit may affect whether these earmuffs suit extended wear. The listing's 30 dB SNR and passthrough descriptions are product claims, not confirmation of customers' experiences.

Negative themes

Mixed feedback

Sound quality and noise reduction receive mixed feedback, as do comfort and battery life.

Frequently asked questions

Does this model use active noise cancellation?

No. The supplied description calls it a noise-isolating ear protector that blocks sound with a physical barrier. Aware passthrough uses microphones, but the page distinguishes this from active noise cancellation.

Can Bluetooth and Aware be used together?

The listing says they can be used at the same time. Aware volume can be adjusted or turned off from the right earcup.

What hearing-protection rating is listed?

The page claims EN 352 compliance and an SNR of 30 dB. It also says the foam cushions block 30 dB. Treat these as listing claims, not independent verification.

Do I need Bluetooth connected to be protected?

The listing says the foam ear cushions provide noise blocking even without a Bluetooth connection. Follow workplace rules and choose protection appropriate to the noise exposure.
