    Sordin SFA (Flexible Attenuation) Gel Upgrade Kit

    Has anyone tried one of these? I have a set of Sordin Supreme-X that I seldom use because I want a higher NRR - this would seem to increase it substantially.

    Very interested in this because my Sordin muffs were not cutting it with my Open gun. Recently got Howard Leight 32 db muffs and they are much better in reducing noise, but the hearing is not as good as with the Sordins.
    Likes pretty much everything in every caliber.

    Definitely want to try one out. If it works I'll be forced to buy another as I have 2 sets of Supreme Pro X.

    It appears there’s an extra layer of foam and the rings provide extra room needed for the foam. With the foam layer between the speakers and your ears, I can’t imagine that this wouldn’t negatively impact the sound quality of the speakers. Will be interested in people’s experiences with this.

    When indoors or when RO-ing Open shooters, I put my Sordins over my Otto earbuds, still can hear everything perfectly clearly and get more than enough concussion protection. I used to use a set of Surefire pressure valve plugs under the Sordins and those are another good solution to increasing the performance of the Sordins indoors or around comps.

    I would like these standing next to SBRs at the indoor range. Looks like a good solution.

    Pay $105 to bring a $250 muff up to par with a $68 muff?
    I only need to hear "Load and Make Ready" etc at a match. It isn't a concert. For solitary vice, a good passive at half the weight is better.

    "Awaiting NRR testing for North American standards"

    I'd want to see that the testing backs up the claims, before depending on that, and spending money on it. 32db NRR would be great, but that requires the "distance ring."

    It appears there’s an extra layer of foam and the rings provide extra room needed for the foam.
    The real reason for sacrificing NRR, and going with low profile ear pro like the Sordins, is for use with a helmet (and comms if part of a tac team, but there are other alternatives for comms). I wonder how much the "distance ring" affects the use with some helmets.

    There are other less expensive ear pro that offer better NRR, at 26dB and one at 30 dB, if use of a helmet isn't an issue:
    Howard Leight Impact Pro (30dB NRR)
    3M Pro Protect (26dB NRR)
    Peltor Tactical 500 (26dB NRR)
    Walker XCEL 100 & 500 (26dB NRR)

    Some of those offer comm solutions too. All either have gel upgrades available, or are included (3M Pro Protect).

    If the testing backs up the 32dB claim I'd upgrade a set of MSA Sordin Supreme Basics I have, but don't use, except with a helmet, and start using them for regular range work. However, I am skeptical that this kit can actually get that NRR, due to the small size of the set.

    The price does seem high - with shipping you're close to the price of a new set of Peltor 500s.

    The kit does include gel cups (approximately $40), but many of us with Sordins have long since upgraded to those. The attenuation rings are sold separately for $30/each - unfortunately the upgraded foam inserts for the higher NRR do not appear available for purchase separately.

    If there was a kit with the rings and foam for $65 without the gel cups (and with more reasonable shipping costs), I'd give them a shot.

    I just emailed my contact at SRS and asked, also interested in this as well.
