Great communication and an all around honest broker. I upgraded my SR225x with ear pads and aluminum blocks. Love them and they feel and sound amazing. Great upgrade. Thank you!!

I bought ear pads and a headband, they are a major improvement over the Grado products. The ear pads are well made and far more comfortable than the stock Grado pads. I've tried both the G and L styles, the Nyczaj style is far superior. A bit of a hybrid of both types. I can't put a finger on the sound difference, maybe there isn't one and my ears are just happier with the better fitting pads. Shipping was as expected to the USA. Well done!

Das Warten hat sich gelohnt. Das Headband und die Gimbals sind exzellent verarbeitet, verbessern den Tragekomfort meiner Grado
RS2x.

Best ever, great sound and high quality.

Perfectly crafted product that perfectly replaces the original headband and gimbals which are plastic and shitty.
Price-performance ratio 11 out of 10.

The Nyczaj earpads are a marked improvement over the stock Grado earpads in every area of sound presentation... Old set of RS-1's...New life...Fun

Great customer service, quick shipping (for something travelling thousands of miles), and nice products.
Would purchase from again.

Excellent service, managed expectations about timescales very well, good product.

Very well made. Wish the price point was a tad lower, but the quality is undeniable. Grado is famously horrible for the cords and headset, so this was a huge jump in comfort and quality.

That’s real craftmanship (hard to find nowadays)! Excellent quality, my Grados are as good as new.

Excellent project ; with exceptional packaging for products shipped. Highly recommend!

Przem is so good to deal with and his products ooze quality.
If you're a Grado fan on any level then take your ownership experience to the next level with Nyczaj.

Great products and the quality and craftsmanship were outstanding.

Everything as expected. Excellent quality and superior customer service.

An outstanding, handcrafted product. Top notch service by Przem and even if I cannot explain it, doing A/B comparison, there was a harshness and sibilance with the previous "premium" pads I had that simply disappears when I put on these. It's friggin' magic! I love my Grados again. Thank you Przem.

With Nyczaj's mods somehow my favorite pair of headphones became even better. I found the comfort to be greatly improved, especially in long listening sessions. The build quality is immaculate and could not be any better. The earpads are an immense upgrade and I had a smile on my face the first time I listened to music with them. I had high expectations prior to installing these mods and they met and even exceeded those expectations.

I hope to do business with you again in the future!

Excellent product; thank you!

Wonderfully constructed and comfortable headband thst definitely upgrades my Grado SR325x

Nyczaj Audio's foam earpads have made an improvement to my Grado SR325X headphones. These are already a very good design, but the one thing that irritated me was the original rigid foam earpads that didn't fit that comfortably. As other reviewers have noted, the Nyczaj earpads improve the "tightness" of the bass response (and I would thankfully agree with this). But, equally important, they are now so much more comfortable to use :-)
Nyczaj have made a great set of headphones even better!
