The A231 Large-Diaphragm Condenser Microphone from Audix is an ultralow-noise condenser mic designed for demanding studio use. Designed with a larger-than-average effective diaphragm, a highly directional cardioid pickup pattern, and a rugged, machined aluminum housing, the A231 is a versatile studio mic that handle voices and instruments with ease, imparting natural warmth with impressive detail.

The A231 sports convenient integrated hardware to make recording easier than ever, with an integrated vibration-reducing shockmount that eliminates the need for bulky external shockmounts, and a built-in acoustic foam filter and steel alloy grille for avoiding plosives and sibilance. The extremely low-noise preamp circuitry produces clean signals, and an active driven shielding helps to protect the preamp-to-capsule connection from obtrusions like capacitive coupling. The microphone includes a zippered carrying case for safe transport to and from recording locations, and the included snap-on mic clip makes the A231 easy to mount on any 5/8" or 3/8" stand or boom.

Stylish
Size: Large, Color: White
This Alimens & Gentle Oxford shirt is honestly a great addition to any wardrobe and completely exceeded my expectations ⭐⭐⭐⭐⭐. The material thickness is spot on. It’s not too thin and not heavy either, which makes it perfect for both work and casual wear. The fabric feels sturdy and well structured without being stiff or uncomfortable. The style is clean, classic, and versatile. It looks sharp enough for business or office settings, but you can easily dress it down for a more casual look. The white color is crisp and polished, and the cut gives it a modern, put together appearance without feeling too formal. Quality really stands out with this shirt. The stitching is neat, the buttons are secure, and everything feels well made. It holds its shape nicely even after wearing it all day, and it doesn’t feel like one of those shirts that loses structure after a few washes. Comfort is another big win. The stretch in the fabric makes a noticeable difference, especially when moving around, sitting, or reaching. It feels flexible and breathable, and you don’t feel restricted at all. It’s the kind of shirt you can wear from morning to night without feeling uncomfortable. Wrinkle resistance is impressive. Even after a long day or sitting for hours, it still looks fairly smooth and presentable. A quick hang or light touch up is all it needs, which is great if you’re trying to save time. Value for money is excellent. For the price, you’re getting a stylish, comfortable, and well made shirt that easily competes with much more expensive brands. It looks professional, feels great, and performs well. Overall this shirt checks all the boxes. Great material, sharp style, solid quality, comfortable fit, and very good wrinkle resistance. I’d definitely recommend it and would happily buy more in different colors.

Work casual shirt that travels well:
Size: Large, Color: Dusty Blue, Size: Large, Color: Dusty Blue
This shirt runs true to size with a bit of room for more. The material is a bit stretchy which helps keep the shirt looking great without major wrinkles. The shirt itself is comfortable and feels like it'd last through many washes and the care instructions are fairly simple (cold wash and low dryer). This particular color is unusual and compliments many outfits. Given the quality, this is a high value item. Just go easy with the iron.

Gorgeous blue color, fits me very well, nicely made and comfortable
Size: Large, Color: Dusty Blue, Size: Large, Color: Dusty Blue
I'm 6'1" 180lbs, sleeve normally 34" and neck 16", and this fits me pretty much perfectly. The material looks really good, I find this particular shade of blue (pattern) to just look really cool. Slightly darker than a typical men's blue shirt, with a slight bit of sheen. Its a medium thickness fabric, not flimsy feeling at all. I find this comfortable. Its smooth to the touch although I always would wear an undershirt personally. Claims to be Italian design? The cut to me seems to be a very standard look, no frills but "sharp" to my eye. The packaging did a good job of protecting the shirt, though it did show up with some extra creases. But that doesn't really matter since it would have needed an ironing before first wearing it regardless. And I do appreciate that the packaging was not excessively wasteful of plastic etc. I haven't worn it a zillion times yet so I can't comment on longevity. Given the price around 22 bucks I'd say this is a good value. Not sure why this color was slightly more expensive (10%) than white or regular blue.
