The SA-iEM2EF splitter cable is built for musicians, DJs, and content creators who need to share audio from one device to two destinations. Whether you're splitting headphone monitoring between band members or sending your phone's output to multiple speakers, this 10-inch cable handles stereo-to-dual-mono splitting with professional reliability.

This splitter takes a stereo 3.5mm output and splits it into left and right mono signals on separate 1/8" female jacks. Connect your phone, laptop, or MP3 player to the male end, then plug two devices into the female outputs to share your audio source. The compact 10-inch length keeps connections tidy without excess cable clutter.

Oxygen-free copper conductors deliver clean signal transfer, while the spiral shield construction provides flexibility for repeated use. The cable splits stereo signals properly, sending the left channel to one output and right channel to the other, making it ideal for dual headphone setups or connecting to two powered speakers with 3.5mm inputs.

Perfect for band rehearsals where multiple musicians need to monitor the same click track, DJ setups splitting cue signals, or house parties where you want music playing through multiple Bluetooth speakers simultaneously. Also works great for recording scenarios where you need to send audio to both headphones and a recording device.

Simply plug your source device into the male 3.5mm connector and connect your two destination devices to the female outputs. No additional cables or adapters required.

Backed by Seismic Audio's one-year warranty and ships fast to get your audio splitting setup running quickly.

Frequently Asked Questions

What devices can I connect with this splitter cable?

Connect any device with a standard 3.5mm headphone output like smartphones, tablets, laptops, MP3 players, or audio interfaces to two destination devices with 3.5mm inputs. This includes headphones, earbuds, powered speakers, or recording devices that accept 3.5mm connections.

How does the stereo splitting work on this cable?

The SA-iEM2EF splits a stereo signal into separate left and right mono outputs. Your source device's left channel goes to one female connector, and the right channel goes to the other. This means each connected device receives a mono signal, not a duplicate stereo signal.

Can I use this to connect two headphones for shared listening?

Yes, this cable works well for sharing audio between two sets of headphones or earbuds. Keep in mind that each person will hear only one channel (left or right) of the original stereo mix, so it works best with mono content or when you just need basic audio sharing.

Will this work with my phone and two Bluetooth speakers?

This cable only works with wired connections through 3.5mm jacks. If your Bluetooth speakers have 3.5mm auxiliary inputs, you can connect them that way, but the cable won't interface with Bluetooth functionality directly.

Do I need any additional cables or adapters to use this splitter?

No additional cables are required. The SA-iEM2EF provides all the connections you need - just plug your source device into the male end and your two destination devices into the female ends. The 10-inch length handles most desktop and close-range applications without needing extension cables.
