What size are these earmuffs?

ISOtunes LINK 2.0 earmuffs have an adjustable headband and are designed to fit head sizes ranging from small to large.

What's the difference between noise-cancelling and noise-isolating?

LINK 2.0 is a noise-isolating ear protector, meaning it blocks noise with a physical barrier (earmuff) while wearing the product. Alternatively, noise-cancelling products produce an inverse sound wave to reduce noise while the product is turned on.

Is the LINK 2.0 rechargeable?

Yes, the LINK 2.0 has a 50 hour rechargeable lithium ion battery. The battery can be swapped for three AAA batteries for 100 extra hours of battery.

Do I have to use the boom microphone?

No, the earmuffs have a built in microphone for phone calls. The boom mic can be purchased separately and used for clearer phone quality in loud environments.

Can I use these at work?

LINK 2.0 is an OSHA compliant hearing protector with a NRR of 25 dB and they are Bluetooth enabled for phone calls and radio communication. Please abide by the rules established by your place of employment.
