If the rating is correct, yes those should work. I'm a little skeptical of the brand and 35 dB rating, though. A reputable brand like Howard Leight or 3M max out at 30 or 31 dB. The Howard Leight L3 and the 3M Peltor Optime 105 are similarly priced, and I honestly would trust their rating more.
These are the ones I have. Nothing special, but get the job done
Nothing like The US Nats at Indy. My dad took me to my first one in 88 when I was 6…I missed my first one since last year as I moved to the western US and couldn’t make it back. I got to go to the Vegas race…it just isn’t the same as Indy though.
