Didn’t work for what I needed though. *by E***G on July 25, 2021* It didn’t work for me like i needed it to. I was trying to get my wireless Bose over ear headphones to connect with my desk phone but I don’t think the desk phone allows for me to use my mic with this or any thing like it. The quality of material was great and I could hear through the headphones very well! I just couldn’t talk with it. Not their fault though so that’s why it still gets 5 stars ### ⭐⭐⭐⭐⭐ Worked well for desk phone (then they took the phone away) *by B***T on June 1, 2025* For the 2 or 3 months I was able to use this cable with a gamers headset w/mike, it worked well. I was finally able to use my phone comfortably (I wear on-the-ear hearing aids).Then they took the desk phone away, and replaced it with a app on my PC. ### ⭐ Not worth it *by L***Y on January 27, 2023* I wanted to connect a new headset to my office phone but needed one just like this. The plug in on the phone jack side works fits to a normal landline, and the other side also fits the normal aux/phone cables. However, once I plugged it in I could barely hear anything even with the volume turned up, the other person said they couldn't hear me either. It got returned the next day ## Frequently Bought Together - VoiceJoy Standard 3.5mm Jack Smartphone Headset Adapter Cable Converter to RJ9 Plug for Cisco Unified Office Telephone 7970 7940 7941 7942 7971 etc - Headset Adapter Cable 3.5mm Smartphone Headset to RJ9/RJ10 Phone Adapter for ONLY Cisco 7940 7970 7960 6900 8900 Series Phones - Callez RJ9 Telephone Training Splitter, Compatible with Plantronics, Mitel, Cisco, Yealink, Avaya, Polycom, ShoreTel, NEC, Aastra, Nortel, GE and Other IP Phones, Easy to Use --- ## 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.dk/products/54924634-standard-3-5mm-jack-smartphone-headset-adapter-cable-converter-to](https://www.desertcart.dk/products/54924634-standard-3-5mm-jack-smartphone-headset-adapter-cable-converter-to) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-05-05*
