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

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 *by on Reviewed in the United States March 16, 2024* 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 *by on Reviewed in the United States December 31, 2024* 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. ## Frequently Bought Together - MillSO 1/4 to 3.5mm Instrument Cable, TRS Headphone Adapter 6.35mm Female to 3.5mm Male 1/8 to 1/4 Stereo Audio Adapter for Amplifier, Guitar, Piano, Speaker to Phone, Laptop, Headphone - 12inch/30cm - ANDTOBO 1/4'' to 3.5 mm Stereo Pure Copper Headphone Adapter, 3.5 mm(1/8'') Plug Male to 6.35 mm (1/4'') Jack Female Stereo Adapter for Headphone, Amp Adapter, Black 2-Pack - MOBOREST 3.5mm M to 6.35mm F Stereo Pure Copper Adapter, 1/8 Inch Plug Male to 1/4 Inch Jack Female Adapter, Can be Used Conversion Headphone adapte, amp adapte, Black Fashion 2-Pack --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.lk/products/361237642-millso-1-4-to-3-5mm-instrument-cable-trs-headphone](https://www.desertcart.lk/products/361237642-millso-1-4-to-3-5mm-instrument-cable-trs-headphone) --- *Product available on Desertcart Sri Lanka* *Store origin: LK* *Last updated: 2026-08-26*
