MillSO 3.5mm to 2x RCA audio cable 10m
Product description
If you want an easy way to connect a mobile device or MP3 player to an RCA enabled speaker, this MillSO cable is a straightforward solution. The 3.5mm to 2 RCA stereo design helps you transfer audio with less fuss, using one lead instead of adapters. With a 10 m length, you can place your phone, tablet, or laptop where it is convenient while still reaching the audio system.
Built for everyday listening, the cable uses dual shielding and oxygen free copper conductors, which are intended to help protect your signal for clean stereo output. The connectors are gold plated and corrosion resistant, and the RCA plugs use the standard red and white colour coding to keep left and right channels clear. 😊 It is also described as bidirectional for audio transmission, so you can swap how you connect depending on which device has the RCA jacks and which one has a 3.5 mm aux port.

Key features


This MillSO RCA to 3.5mm cable is designed to bridge the gap between modern devices with a 3.5 mm headphone or aux output and audio gear with RCA inputs. That means smartphones, tablets, and MP3 players with a 3.5 mm auxiliary port can play through an AV receiver, amplifier, stereo receiver, or other RCA enabled speaker systems. It can also be used in the opposite direction when you are routing audio from a device with RCA outputs into a 3.5 mm speaker. 🔊

The cable comes with gold plated RCA connectors that are described as corrosion resistant, helping you keep reliable contact over time. It also features easy grip RCA heads, so plugging in and unplugging tends to be a bit more practical during regular use. If you are setting up a small home audio station, the red and white male RCA plug colours help reduce confusion when you are matching channels. 🎶

What it’s worth noting

Double check the plug direction if you are switching between sending audio from a 3.5 mm device to RCA, and sending from RCA gear into a 3.5 mm speaker. The instructions note that when transferring music from an RCA output device to a 3.5 mm speaker, you should exchange the red and white plugs when connecting this way. That is a small detail, but it can make a difference if you notice the stereo channels do not sound right.


It can be a practical choice for anyone who wants more cable reach without crowding their setup, since the lead length is stated at 33 ft or 10 m. The description also highlights multi device compatibility, so it should suit typical use with smartphones, MP3 players, tablets, and laptops that have a 3.5 mm auxiliary port. 🤝

Worth noting, the cable is described as having polished metal and dual shielding to help protect the signal from interruptions, which supports reliable day to day listening. You also get a warranty stated as 12 months for MillSO products, and the description says it can be extended to 18 months by contacting their support team.
Who it’s for

It’s a good fit if you frequently play music from a mobile device and want it to sound through an RCA enabled speaker or receiver, without relying on Bluetooth. It makes sense if your AV receiver, amplifier, or other compatible audio equipment has RCA inputs and you want a simple wired connection. You may also like it if you want a single cable that can handle common device setups using 3.5 mm aux outputs. It might not be a great match if your audio gear uses only digital inputs, since this lead is specifically described for 3.5 mm and RCA audio connections.
