I ordered with confidence due to Amazon's Free Returns (no risk if it was junk) but was delighted that the device is exactly as described.Connection was tight and secure, properly sized for my RJ9 connectors. Perhaps the reviewer Espey received a defective product?Bottom Line: I'd buy it again. ### ⭐⭐⭐⭐ Didn’t fit my phones *by K***Y on March 19, 2023* Didn’t realize phone had different size cords. Wasn’t able to use and Forgot to send back in time. ### ⭐ Is the size of it some kind of joke? *by E***Y on November 30, 2018* I have 2 different RJ9 telephone line and neither fit into this splitter, not sure if this item is defective but I'm highly disappointed and wouldn't recommend the product. One line was slightly too big and the other one fits inside but slides right out so wouldn't be much of any use. ## Frequently Bought Together - SinLoon RJ9 Telephone Training Adapter Y Splitter RJ9 Headset Extension Cord Adapter 1 Male to 2 Female Connector for IP Phones (2 RJ9 FM) - AGPTEK® Hands-Free Call Center Noise Cancelling Corded Monaural Headset Headphone for Desk Telephone with 4-Pin RJ9 Crystal Head - 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.com.kw/products/105041174-sinloon-rj9-telephone-training-adapter-y-splitter-rj9-headset-extension](https://www.desertcart.com.kw/products/105041174-sinloon-rj9-telephone-training-adapter-y-splitter-rj9-headset-extension) --- *Product available on Desertcart Kuwait* *Store origin: KW* *Last updated: 2026-05-21*
