Specifications Size:3.3cm*2.8cm*1.3cm Material: Aluminum alloy Weight:14g Review: Great little switch box for audio selection. - Small and compact switching unit, options are, 1 in and 2 out, ie pc in and speakers or headphones out, or, 2 in and one out, ie, 2 audio sources and 1 out to head phones/speakers. No loss in sound level or quality and no messing with cables once connected. Feels very solid (metal case) and a simple push switch to make your selection. I had a problem when I was changing over from speakers to headphones on my pc and this device stopped that issue. Happy to recommend this audio switch unit. Review: Excellent Little Switch! - I needed to connect two sources to my soundbar. I tried a Y type splitter lead, but I got terrible distortion, so I needed a switch. Ordered this and an extra jack to jack lead. This arrived, I unpacked it and found the pack included a jack to jack lead, so I could have saved myself a fiver! I connected the two sound sources into the switch and the switch to the soundbar, switched everything on, and it all worked perfectly! Clear sound from both sources and a simple press of a button to switch between the two. It does everything I need at a good price, and it feels sturdy enough to last. I'm very pleased with my purchase! ## Features - 【Bidirectional 3.5mm Audio Switch】Plug and play, no power supply required. 1X2 (one input to two outputs) or 2X1 (two inputs to one output) 3.5mm interface audio selector designed for easy switching between multiple audio receiving devices (speakers, headphones, etc.) or audio sources (mobile phones, computers, etc.). - 【Metal Casing, Small And Exquisite】Small and compact, beautifully crafted with a metal CNC casing.

Currently allowing me to share my Dell PC output with a Majority CD player and a Lepy amp. Can't comment om longevity as I've only used it for a few hours. I have docked a star as the the selection button does seem a bit fragile (but as said works fine). It was also quite expensive for what it does. But so far happy with my purchase. ## Frequently Bought Together - COOIDEA 3.5mm Stereo Audio Switcher（1 in 2 Out /2 in 1 Out） with 3.5mm Audio Cable, 2 Ports AUX Audio Speaker Selector for PC Phone Laptop Headphone - Nanxudyj 3.5mm Audio Cable 6ft/1.8M, Stereo Aux 3.5mm to 3.5mm Cable 90 Degree Long Aux Cable Aux 3.5mm Male to Male Right Angle TRS Cable Compatible for Headphone,Tablets, Speakers, 24K Gold Plated - 2 Pack AUX Cable, (6.6ft/2m, Hi-Fi Sound) 3.5mm TRS Auxiliary Audio Cable Nylon Braided Cord Compatible with Car,Home Stereos,Speaker,iPod iPad,Headphones,Sony,Echo Dot,Beats (Grey) --- ## 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.kr/products/525864126-cooidea-3-5mm-stereo-audio-switcher-support-1-in-2](https://www.desertcart.kr/products/525864126-cooidea-3-5mm-stereo-audio-switcher-support-1-in-2) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-05-27*
