Review: 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!
Review: Perfect for what I needed - Works perfectly!!

## Questions & Answers

**Q: Can it take a 1/4 mono signal and split it into L/R channels on the 1/8 plug?**
A: No, you need a purpose built adapter for that.

**Q: Is this cable 12"tip to tip, or is is a 12" cable?**
A: Tip to tip length is 14.25" . I don't know where the 12" measurement comes from, but the cable length itself (minus both connectors length) is 10.5" Hope this helps.

**Q: Does this work for a talkbox?**
A: This is a passive adapter which simply allows an audio cable with a male 1/4in. connector to be plugged into any audio device having a 1/8in. socket.  

There is every reason to believe that it will work with a "Talk Box" if that device needs such an adapter.

**Q: Can this work in either direction, i.e., 3.5mm to ¼" as well as ¼" to 3.5mm?**
A: Dear Amazon Customer,
Yes, this MillSO 1/4 to 3.5mm adapter can work in either direction (3.5mm to ¼" as well as ¼" to 3.5mm).

Thank you for your question. Hope this answer will help you, if you have any other concerns, please contact us via support@millso.com, we will always be more than happy to assist you.
