Next Generation
Custom Bluetooth Cables
For IEMs + Headphones

Redesigned Module

Built from the ground up, we implemented the latest features, along with unique and innovative ones to an all-new module design that vastly surpasses our original and all others on the market.

BT Version 5.0

Now using the latest bluetooth technology that improves power, range, connectivity, and reliability.

Complete Codec Support

Our new module supports all codecs, including SBC, AAC, aptX, aptX-LL, and the newest addition, aptX-HD.

LDAC Support

We are proud to announce that we have partnered with Sony in bringing their proprietary LDAC to our custom cables. This audiophile-grade codec offers up to 990kbps for hi-res wireless performance.


Not only can you charge via computer, you can connect to it and listen to your music and videos. Supports up to 24 bit / 96kHz and no software or firmware necessary.

Hybrid Functionality

Our custom cables can connect up to three sources at the same time - two via bluetooth, one via computer/source. Play audio from one source and switch to another without any hassle. It's that simple.

LED Indicators

We felt one was not enough, so we incorporated three LED indicators. One for power/battery life and two for each paired device. This makes it easier to know which device is paired, which device is out of range or disconnected, and how much battery the module has left without the need to check your mobile screen.

USB Type C

We've added the latest USB for faster charging. You'll be able to use the module at the same time, whether it is USB DAC or Bluetooth.

Two-Button Commands

Hold two buttons in combination to enable or disable features such as LED lights or removing paired list.

Pair button

A dedicated pair button has been added to connect existing and new devices while avoid pressing unintended commands.

Hard Reset

Next to the pair button is a hard reset if you ever wish to redo your settings quicker and start fresh again.


Now moved to the bottom front to be as close to the mouth as possible. Users on the other end will be able to hear you more clearly. This includes voice commands via Siri, etc.

Balanced Configuration

Just like 2.5mm and 4.4mm wired terminated cables, our custom bluetooth cables are also balanced for better quality sound and performance.

Cable Styles

You can now choose where you want the module to be placed on your cable. You can select Default (located on the right side) or Pendant (center of the cable).

UP-OCC Wiring

All custom bluetooth cables feature our award-winning, high quality signature UP-OCC wires using Type 6 litz design with special dampening cores for premium performance and our proprietary PS insulation that is durable, flexible, and soft.

In-House Designed Connectors

Our PS designed connectors features high quality gold plated copper based contacts with thick anodized aluminum enclosure to ensure the best quality product possible. Available in 2-pin, MMCX, A2DC, IPX/T2, HD8XX, Audeze, and many more.

Interchangeable Sliders

For default style, use the included anodized aluminum cable slider at any time to adjust fit. They are easily removable and can be interchanged for the different color or size.

Firmware & Hardware Updates

Users will be able to download the latest firmware to improve and add new features to their module.

In addition, if we release a newer module, users will be able to send in their cable to upgrade, making our BT cables futureproof and last for many years.

Check back here periodically for updates.

Handcrafted in the USA

Design and assembly continue to be performed in-house in Los Angeles, California, USA.

Premium Packaging

All orders come with the following: Microfiber cloth, leather cable pouch, Digital Start Guide, and a complimentary 4' USB Type C to USB Type A cable.
