There's too much noise on a slightest touch on it, and the voice echoes..But again, I think this all right for price.Update after a month:I find the noise issue not so critical, I can only feel the loud noise amplify while connecting/disconnecting and if moved too much, apart from that, the jack has been very helpful for me in all my meetings, upvoting it to 4 stars!! ### ⭐⭐⭐⭐⭐ Good Purchase *by on Reviewed in India 11 July 2026* Works beautifully well. I use this at work on one of the desk phones. Please make sure there is an option being the phone for headphones before purchasing. The vendor reached out prior to delivery to make sure it was not a mistake. Asked for make the the phone to check compatibility. Thank you for that. --- ## 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.com.ar/products/89486561-rj9-to-single-3-5mm-smartphone-headset-adapter-cable-cisco](https://www.desertcart.com.ar/products/89486561-rj9-to-single-3-5mm-smartphone-headset-adapter-cable-cisco) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-08-28*
