About this item
- SHARE YOUR ENJOYMENT: Extend the enjoyment with Duet-Extra headphones. An add-on headphone for the Duet, Quartet 5049 or Audiplex2403s kits, use this product to enable a friend or family member to wirelessly view TV or a movie, or listen to music right alongside you. Up to 100 headphones can be connected to the transmitter of each of these kits. Note: Headphones not for purchase independently.
- SYNCHRONIZED AUDIO & VIDEO: Enjoy perfectly in-sync visuals and audio with the Duet-Extra headphones. Using 2.4Ghz RF technology, you will find the lag reduced down to ~ 30ms - practically nothing. And even if you add additional Duet-Extra headphones, to your existing Duet/Quartet 5049/Audiplex 2403s transmitter, no lip-sync delay will be introduced: everyone will enjoy the same great experience.
- PERSONALIZED SOUND SETTING: The Duet-Extra headphones come with individual volume controls, enabling you to set the sound level that’s right for you. And no worries - you will not impact the volume level of other headphones that may be connected to your existing Duet/Quartet 5049/Audiplex 2403s transmitter.
- HEAR THE CONVERSATION: If you struggle to distinguish voices from background noise on screen, activate Clear Voice mode with the simple click of a button on the Duet-Extra headphones. This digitally enhances the on-screen dialogue so you’ll be able to understand conversations clearly.
- FLEXIBLE FIT: The Duet-Extra headphones have an adjustable stretchy headband, with rotatable ear cups, enabling you to find the perfect fit for your needs. In addition, the soft memory foam earpads are gentle on your skin for long stretches of wear, and easily replaceable if needed.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
