Don�t miss a thing

The human voice can convey a great range of emotion. But traditional wired telephones only transmit a small fraction of that range.

Mobile devices are better, using wideband audio to transmit sound with an expanded frequency range.

But super wideband audio allows an even larger range of frequencies, so voices sound more natural�which means you�ll feel closer to the people you care about.

So you don�t miss the inflection in your uncle�s best joke. And you can hear your granddaughter�s first words as clear as if she were sitting on your lap.

Super wideband audio can help you stay connected. But to take full advantage of it, you need a headset that�s been designed to provide the enhanced audio experience that super wideband audio allows.

Don�t miss a thing
Low bandwidth? No problem.  

Low bandwidth? No problem.

But what if you�re on a slower connection? Or your network is congested?

Don�t worry. Super wideband audio lets your Logitech headset use less bandwidth�50% less�to help deliver crystal-clear audio that keeps you connected to your friends and family.

And super wideband audio even adjusts in real time when there�s more traffic on the network, so you always get great sound quality�even in bad conditions.

Hear voices, not background noise

We�ve all been there. You�re talking to someone and their dishwasher is going. Or the kids are screaming. It�s almost impossible to hear.

Your Logitech headset helps block out irritating background noise�to let you focus on your conversation.

Hear voices, not background noise.
Logitech makes Internet calling easy.  

Logitech makes Internet calling easy

We build all of our headsets with one goal in mind�keeping you connected to the people you care about.

So whether you want to experience the pure digital audio of a USB connection or the freedom that comes from fast, reliable wireless, we�ve got a headset that lets you stay close�even when you�re far away.
