Review: Perfect Adapter for My Gaming Setup! - Transitioning from a gaming environment to my RodeCaster Pro 2 has been seamless, all thanks to the MillSO 1/4 to 3.5mm Headphone Adapter. Here's what I love about it: Pros: - Effortless Conversion: Just plug and play, and I'm good to go. - Sturdy Design: It feels robust and doesn’t seem like it'll wear out any time soon. - Clear Sound: No static, buzz, or any other disturbances. Pure, clear audio every time. Cons: - Honestly, none so far! Final Thoughts: If you're in need of a reliable adapter for audio conversions, especially for high-end equipment like the RodeCaster Pro 2, look no further than this MillSO adapter. It’s got my vote!
Review: Superior to standard adapter - works with 4 pole plugs! - The cable is made from quality materials, including sturdy female and male plug ends and thick rubber surrounding the wires. It has excellent sound quality. I A/B tested against multiple adapters including high quality studio options and this cable sounds as good or better than all of my others. The added cable length makes it easy to swap multiple headsets in my home recording studio. Most importantly for me is that this works with 3 AND 4 pole 3.5mm plugs, meaning I can use my stereo reference monitor headphones (3 pole), then quickly swap them for a gaming-type headset (4 poles) to hear my recordings through different sounding headphones. The audio signal with 4 pole headphones doesn't short out like it does with other adapters. Excellent build quality. Excellent sound. Great price. Highly recommend.

## Questions & Answers

**Q: Am I missing something? I connected this to my electric guitars and only got mono. I expected stereo.**
A: The output jack of 98% of electric guitars has a hot signal on the tip and a ground on the sleeve. That's why instrument cables have a tip and a sleeve -- to accommodate those connections. Plugging a stereo cable into a monaural guitar will not make it stereo. You're only get signal to the tip -- the left side output. If you want to hear out of both sides of earphones, you'd first have to run your guitar to a mixing desk, then to your headphones.

**Q: Do these work with beats headphones? I have a pair of the newer ones**
A: Dear MillSO Customer,
Thank you for your question.

If your bose headphones have a standard 3.5mm plug, you can test. This 1/4 to 3.5mm adapter is used to connect smartphones, tablets or headphones with standard 3.5mm plugs to audio devices with a 6.35mm stereo jack.
