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).

The cord is very practical ### ⭐⭐⭐⭐⭐ Headphones adapter *by S***. on February 16, 2026* It works great ### ⭐⭐⭐⭐⭐ Well built, nice connections, significant improvement in headphone sound -- no kidding *by G***R on February 13, 2021* 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! ## Frequently Bought Together - MillSO 1/4 to 3.5mm Headphone Adapter, TRS 6.35mm Female to 3.5mm Male 1/8 to 1/4 Stereo Audio Adapter for Amplifiers, Guitar, Piano, Home Theater Devices to Phone, Laptop, Headphones - 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 - VCE 6.35mm (1/4 inch) Male to 3.5mm (1/8 inch) Female Stereo Audio Jack Adapter for Aux Cable, Guitar Amplifier, Headphone, 2 Pack --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.it/products/143750033-millso-1-4-to-3-5mm-headphone-adapter-trs-6](https://www.desertcart.it/products/143750033-millso-1-4-to-3-5mm-headphone-adapter-trs-6) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-05-13*
