No instructions, but the new ear seals were easy to install and instantly made my old XLc headset look like new. Very easy to snap out the old seals and snap in the new.
Poor choice of construction material
The film covering on the ear seal is flimsy and fragile. Over time it disintegrated. It is not durable. The headset was expensive and replacing the seals occasionally makes sense. They install in seconds.
Super headset AND company
I have owned a variety of different headset in the 29 years that I have been flying and these are by far the absolute best. Superb noise cancellation and very comfortable. HOWEVER, beyond a great headset, you will not find better customer support anywhere. Everyone you deal with at Lightspeed treats you like you own the company. They stand behind their products and go way beyond the extra mile with any question or issue you may have. I will never bother with any other headset.
Just like the originals
The replacement seals were exactly what was on the headset when I purchased it. Easy to install.
