Well built, nice connections, significant improvement in headphone sound -- no kidding
I listen to music and watch movies with Sennheiser 599 SE headphones. I've been connecting those using a coiled cable I bought over 10 years ago. Noticed recently that the sound seemed to jump in/out in one of the ears and decided it was time to try a new cable, so I ordered this MillSO cable.The cable arrived nicely packaged, and the materials had a high-quality feel on unpacking. Cable was supple, and connectors looked very nice. When I connected the headphones, the connector had a very nice, snug grip and the male end of the cable had a nice snug fit into my A/V box. Then I turned on the sound...wow! I was amazed at how much better my headphones sounded with this new cable. Being sure that I was probably just imagining, I switched back to the old cable, then back to the new cable. No question, sound was significantly better with the new cable. I know part of that was how bad the old cable was, but some of it has to be because of how good the new cable is.The manufacturer (MillSO) followed up with an email to make sure I got everything ok, and offered an 18-month extended warranty at no additional cost.I'm very pleased with this cable, highly recommend it. Just wish I had gotten it sooner!

Great adapter
I am using this adapter to connect a pair of 1/4" stereo headphones to the 3.5mm stereo audio output from my desk top computer. This set up works great. The adapter is well constructed and feels like it will last years. When I insert the headphones into the adapter you can feel a nice solid click to show the headphones are solidly connected. I have now purchased 2 of these adapters for different computers and headphones. I like them that much. Quality item.

Seems well made, works as expected
We have a "vintage" pair of headphones with only a 1/4 inch plug. Most things today seem to have adopted the 3.5 mm jack (the "1/8 inch" designation is a holdover from history; 1/8 inch is 3.175 mm). The MiLLSO adapter performs exactly as expected. The 1/4 inch jack holds the plug solidly, and the 3.5 mm plug fits its jack perfectly. The cable between jack and plug is nice for our application, though some might prefer a solid unit. Recommended.

Reliable contact, no intermittent noise
This was my fourth 1/4โ- to-1/8โ adapter. The first three all had noisy/loose contacts โ if I touched the connection, the signal would crackle or cut out. This one is the first that holds a solid connection. Itโs $1โ$2 more, but after wasting time returning the others, itโs worth it. Recommended.
