Description: The SC1-HDR4 kit features ACT's most popular Heavy Duty pressure plate paired with a 4-pad rigid race disc. ACT Heavy Duty pressure plates utilize an exclusive diaphragm design to increase clamp load, reduce deflection, and maximize clutch life. Each diaphragm undergoes a four-stage heat-treating process for unparalleled performance. Precision cover stampings provide rigidity and consistency. The 4-pad rigid race disc is made with high-quality ceramic friction materials and features a chrome-moly hub that is heat-treated for strength and durability. Its lightweight, rigid design allows for quicker shifts and smooth, trouble-free service. With the 4-pad rigid race disc, engagement is harsher, but shifting is faster. This disc is well-suited for smaller disc sizes in smaller engines.

Key Features:

  • Feel: Light to moderate pedal effort, aggressive engagement, increased gear rattle.
  • Life: Moderate friction life, extended by ACT's exclusive diaphragm design. Rigid design may increase spline wear.
  • Quality: Carefully engineered, precisely assembled, accurately balanced, uses select ceramic friction materials for high heat tolerance and maximum performance.
  • Recommended Use: Recommended for race use only.
  • ACT Difference: 100% clamp load tested and dynamically computer balanced for smooth high RPM reliability.

Great no-frills Bluetooth wireless headphones
Color: Blue
I did not read the description carefully. It states what devices these headphones are compatible with and "desktop computer" is not one of them. I called Sony and they told me they will work with almost any modern device that has Bluetooth connectivity. I easily wirelessly connected them to my desktop computer and they work great. Strangely the user guide gives instructions on how to use them with Mac and Windows computers, so read the user guide/manual that is linked in the description. If you want to use any of the functions of the Sony Headphones Connect app you will need a compatible phone. If you do not use the app (not compatible with computers) they function as a basic pair of wireless headphones. All rather confusing and the Amazon description does nothing to clear it up. With that being said I connected it easily to my desktop computer. I am no audiophile and do not need a $400 pair of headphones. To me they sound great especially for the inexpensive price. They are NOT noise cancelling headphones and I did not want noise cancelling. They are "on the ear" headphones meaning they are about the size of your ear and press your ears against your head creating a bit of a seal keeping some exterior noise out. Works fine, but if you wear eyeglasses and wear the glasses and the headphones at the same time after a few hours it can become uncomfortable as the headphones press your ear against the arm of the glasses and the arm of the glasses into the side of your head. The charging port on the headphones is USB C and they come with a USB A to USB C cable but no charging brick. I connected mine to my computer with a USB C to USB C cable and it charged fine. 50 hours of playtime on one charge is great. One star for a confusing and unclear Amazon description. 4 stars for a good basic pair of headphones that works with almost any modern Bluetooth device, albeit without the functions of the Sony app (unless you are using it with a compatible phone).

Lightweight, great sound and beautiful color.
Color: Cappuccino
I absolutely love these headphones. The color is great, they're lightweight, feel great on my ears and head. They're great quality and love that they twist down when testing then on my neck so they're not hitting my face. I would recommend this product!

Perfect for me!
Color: Black
Slim/lightweight. Comfortable fit. Good charge. Though my volume was on a 4 or 5 and when I took the headphones off I could hear my music a little. You can’t fold to close them like other styles but I can rotate the earmuffs to make them fit in my bag. Definitely a solid pair of wireless headphones for a good price!
