Good design, but inconsistent photos. I think I got a dull-colored sample.
Color: Walnut Wood
Good, but seeing a lot of inconsistent user photos. Some have extra racks or a little knob for cables. Some mount with the bracket pointing downward (you can reverse it if you want) and with two screws. Also, the block I got is a dull poopy brown instead of the bright & vibrant brown on the photos of the product page & box. Understandable, I suppose-- given the nature of wood. Plastic/metal would certainly be more consistent, but I wanted this to match my black & wood aesthetic of my office. Luck of the draw on the shade of brown that I got, I guess. As nice as this hanger looks and as convenient as it is, the dull color is enough to make me want to just leave my headphones in the desk drawer when not in use. A drawer protects the headphones from dust as well. I don't live at my PC, so having them stowed away when not in use makes more sense for me. I didn't really think this though and got a lemon of a color. Likely a return.

Great for center weight headphones
Color: Walnut Wood
Easy to install for the wall, hang headphones well. Make sure your headphones are center weighted as otherwise they can slide easily

Healthy Trail Mix That Fits My Dietary Needs Perfectly
Flavor Name: Healthy Trail Mix, Size: 1.2 Ounce (Pack of 72)
This trail mix has become one of my new favorite snacks, and I’m really impressed with it. The variety of flavors in the pack keeps things interesting, so I never get bored eating the same thing over and over. Each mix has a great balance of nuts, dried fruit, and other goodies, and everything tastes fresh and high quality. I also really appreciate the portion size of each bag. It’s just right for a satisfying snack—enough to keep me full between meals without feeling like I’ve overdone it. The convenient packaging makes it easy to take on the go, whether I’m working, traveling, or just need a quick bite. As someone who is gluten free and dairy free, finding a snack that actually tastes great and still meets my dietary needs can be a challenge. I love that this trail mix fits perfectly into my lifestyle so I don’t have to worry about hidden ingredients. It’s become a staple in my pantry, and I will definitely keep buying it. Five stars!
