Turns out that my old ones wasn't bad but I still replaced them and they are working fine so far (it has been 1 month).

They seem to last a little longer than the cheaper originals in my machine. This could also be due to me finally getting pressure dialed in for cutting right.

They don't sound to bad out of the box, I made a couple of modifications, and now they sound better.

They are the correct ones and they work fine.

They work fine. I thought they were new when I bought em. Maybe I misread. Timely shipping I cant be mad.

I don't know if they're the best since I have no basis for comparison, but they're working well for me so far.

Not exactly the same as the originals, but they cleaned up my screens nicely.

I found out that I've been over-tightening these but even so they have not stripped.

They seem to hold a charge well. I will report back in 6 moths or so to tell you guys about any updates such as diminished or sustained performance.

I haven't had these long enough to have any idea about how long they will last, but they are working correctly now.

My older systems were toast, had replaced the batteries finally they began to fail to recharge. These are a bit more up to date and cheaper than the older systems...

May give 5 stars but want to see how long they last since I only installed them a few weeks ago

Took a couple minutes to figure out how to snap them on, but the ear pads seem to be solidly on now.  They aren't as soft and comfortable as the originals, by any means, but they seem to still provide decent noise isolation (again, not quite as good as the originals).  For the price, I won't argue.  Maybe they'll soften up with time somewhat; the previous ear pads I had were well-worn, to say the least.

I had to reuse the factory bushings because they were not the same as the ones supplied.  But the shocks are doing their job.
