True Recreation Of A Studio Classic Revered For Warm And Balanced Tones

Balance & Character

The WA-251 is a true recreation of a studio classic revered for its warm and balanced tones. The WA-251 delivers the same sound profile of the original mic, easily considered to be one of the greatest condenser microphones ever created. Known for its natural, rich sound reproduction so often used on vocals and acoustic instruments, the original was used by a long list of legendary vocalists including Adele, Ariana Grande, John Legend, Neil Young, Stevie Wonder, and many more.

A Studio Favorite For Warmth & Depth

The WA-251 captures natural sound with controlled bass and smooth high-end - just like the vintage 251-style microphones. Looking at the frequency response, the WA-251 essentially has an “always-on” 50 Hz high pass filter. With most usable bass frequencies running from 60-250 Hz, the WA-251 is a great choice for capturing lows and mids that sound “tight” in the mix vs. muddy or boomy. The 5-10 kHz dip in cardioid mode smooths out the highs to deliver a smooth top end that never sounds harsh.

Like the original 251-style mic, the WA-251 includes all the features that deliver a complete and professional recording experience.

The WA-251 uses a true reproduction of the CK12-style capsule in the original 251 tube mic. Perfect for recordings where vintage vibe is a must.

Three polar patterns (cardioid, omni, and figure-8) give you a variety of options to choose how you want to capture sound and reject noise.

The WA-251 uses a premium 12AY7 vacuum tube to complement the CK12-style capsule for smooth tone and vintage warmth without harsh high end.

The custom USA-made CineMag transformer drives the bold sound captured by the capsule, delivering the tight lows, present mids, and smooth highs out of the WA-251 circuit.

CK12-Style Capsule

The all-brass CK12-style capsule provides the performance of the vintage original, by smoothing out the top-end and delivering a pleasing, rich tone to the transformer. Unlike later nylon iterations of this capsule, the WA-251 faithfully replicates the clear open top end of the original all-brass CK12 capsule.

Cinemag USA-Made Output Transformer

The WA-251 utilizes an American made CineMag USA transformer. CineMag has a rich history of manufacturing some of the most sought-after American-made transformers. CineMag products date all the way back to World War II (as Reichenbach Engineering) and were pivotal in creating some of the most legendary audio products in the last 100 years. This transformer helps provide the present top end and the LARGE bottom end one would hope to get from a 251-style condenser microphone.

Premium Tube & Capacitors

The WA-251 uses a premium 12AY7 vacuum tube that adds warmth and depth to the microphone’s signal. The WA-251 proudly uses polystyrene coupling capacitors, WIMA film capacitors throughout, and an imported Solen French capacitor on its output.

Hand-Tested, Elite Build Quality

Every single WA-251 is meticulously hand-inspected at Warm HQ in Austin,TX by real musicians and engineers with a passion for superior sound.

Comfortable and easy to set up
Color: Black, Color: Black
I’m happy with this chair. It was not hard to assemble, and it feels stable after putting everything together. The mesh back is comfortable and breathable, so it doesn’t feel too hot when sitting for a while. The seat cushion is also thicker than I expected and feels soft enough for daily use. I like the adjustable headrest and the back support, especially for working at a desk. The chair looks simple and clean, and the wheels move smoothly. Good value for a home office chair.

Exactly the Desk Chair I Was Looking For
Color: Black
had been needing a new desk chair for a while, and this one has been a great addition to my workspace. I use it every day while working, and it feels very comfortable, even when sitting for long periods of time. The seat provides good support, and the backrest helps me stay comfortable throughout the day. Assembly was straightforward, and the instructions were easy to follow. I also like how well it fits in my workspace and how nice it looks. So far, I am very happy with the comfort and overall quality. It has definitely made my workdays more enjoyable.

very ergonomic
Color: Deep Black, Color: Deep Black
I bought this as a replacement for one of those gaming chairs that kills your back with a little lumbar pillow and this one is muuuuch better. the back support is everything you’d need and got rid of my neck pain after long periods of sitting and the seat cushion is supportive but still comfortable. It’s the kind of chair that you don’t really think about much because it’s so natural to sit in that you forget it’s there. The armrests flipping is a really nice feature too. One star off only because the head rest is so far back that i can’t really rest my head on it and every part of the chair that’s cloth is made of the same mesh texture like the armrests and seat. but i have no other complaints this is a good chair

Comfortable Ergonomic Chair for Long Workdays
Color: Black, Color: Black
I’ve been using this chair for my home office, and it’s been a great addition to my workspace. The seat cushion is thick and comfortable, even after several hours of sitting, and the mesh back keeps good airflow throughout the day. I especially like the adjustable headrest, which provides extra neck support when leaning back during breaks. Assembly was straightforward, the chair feels sturdy, and the wheels roll smoothly on my floor. The all-black design also gives it a professional look that fits well in any office setup. Overall, it’s a comfortable and affordable ergonomic chair that offers excellent value for the price.

Sturdy but uncomfortable
Color: Black
The seat itself is sturdy and easy to put together, I’ve now had the product for 8 months and had no issues wear/tear despite nearly daily use, but… it’s not comfy, at all. The seat cushion has a texture to it that scrapes at my legs if I don’t have an extra pillow on it or am wearing shorts. Additionally, the seat pillow is just kind of hard. It doesn’t give very much at all, so if I sit on it for more than an hour or two at a time my butt starts to get really sore. It works as a budget option, but invest in a good seat pillow if you plan to sit in it for any length of time.
