Frequently Asked Questions

UP-OCC, or Ultra-Pure Ohno Continuous Casting is a process of refining wires utilizing a heated mold for casting and extruding, with cooling taking place in a separate process. This leads to larger crystal size and increased purity of up to 99.99999% (or 7N). The benefits of UP-OCC include free from impurities as possible to prevent corrosion, flexibility and fatigue resistance while maintaining conductivity, rapid signal transmission, among others. By working with the best manufacturer of UP-OCC, we are pleased to provide the best quality wires on the market for custom cables.

We offer many options, ranging from copper to palladium plated hybrid. Each wire has its own characteristics in sound and range, so we let our customers decide what they need and prefer, depending on their equipment. All wires are designed in-house and configured for optimal durability, flexibility, and performance.

Here are a few tips to follow:

1. Installation = We provide an instruction card with every cable purchase. Read carefully and follow each step.

2. Burn-in = This is a process of exercising new audio equipment. Some may need 40 hours minimum to reach optimal performing state, but we recommend 100 hours to maximize its potential. This will result in the drastic improvement in sound.

3. Handle with care = The cable will work best when it is not heavily abused, tightly twisted/bent, and when they are connected/disconnected frequently from source. *IMPORTANT: User wear and tear will not be covered under warranty.*

Out of respect for others, we do not comment, publicly or privately, on other products besides our own.

Yes we can, depending on the modification. Contact us with info regarding the product and what you wish to modify.

While TWS modules can only drive sensitive earphones, V3 is designed specifically to work with both higher impedance earphones and high impedance full-size headphones, up to 300ohms!

We use the same material as our wired cables. Each wire has its own characteristics in sound and range, so we let our customers decide what they need and prefer, depending on their equipment. All wires are designed in-house and configured for optimal durability, flexibility, and performance.

All modules support the most popular codecs, including SBC, AAC, aptX, aptX LL, and aptX HD. V3 is the only module that also supports LDAC.

Depends on the device the module pairs with. For instance, iPhones do not support aptX, but has AAC and SBC, so the module will use best performing codec. However, if a device supports aptX, the module will use aptX by default.

Up to 30 feet from line of sight.

Varies greatly based on settings, volume, codec used, application, and usage. On average, V3 can last up to 6 hours. TWS will last approx. 6 hours or more.

It will take up to 1.5 hours if it is charging from 0 to 100%

Absolutely! Leave a note at checkout to let us know if you need the module placed at a specific length.

It is an electronic device that boosts the power, voltage, or current of a signal. Strongly recommended for earphone and headphones that have high impedance and require additional power to drive.

Better quality and detailed output sound. With our Cloud Nine amplifier, it will not only drive In-Ear Monitors, but it has the power to drive the most power-hungry headphones on the market. You can view the Cloud Nine page for more details.

Fuller sound. Impactful bass. Wide soundstaging. Highly detailed. Better clarity. Among other improvements. Visit product page to read what reviewers and customers had to say about its sound quality!

We have tested several 9V batteries (Alkanine, NiMH, Lithium) to verify that it fit and work on the amplifier, and we are pleased to confirm that it will work with all 9V batteries, including the following brands: Duracell, Panasonic, Energizer, Royavac, Tenergy.

All 9V batteries work perfectly with the amplifier. If you are looking for long lasting battery life, you can purchase lithium batteries which will last you for 70+ hours (depending on mAh, gain, volume, etc.) and it will sound slightly better due to its lower resistance/impedance. On the other hand, rechargeable NIMH batteries are a great investment when using the amplifier with high impedance headphones. Alkanine are fantastic all-around when using on trips or away from home, providing great battery life. Precaution: Do not mix batteries. We suggest you use the same exact pair of batteries when in use for better sound and battery life.

If you wish to keep it within a budget, we recommend investing in two pairs of 9V NiMH (rechargeable) batteries. Use one pair for the amplifier while the other pair is being charged. When one pair runs out of battery, switch them out for the fully charged pair.

Production time vary on amount of orders we received, along with repairs. Each product page has its own estimated build time located near the top. Keep in mind that processing time and shipping time are not the same.

Click on "more information" under each dropdown when selected any cable you configure to find out more about a specific option. For some series, you may find some of them having more options than others due to various factors (sleeving, number of wires, braiding, etc.). We have listed all the available options to make it easier for you to understand and making ordering faster.

Connector: The connectors you want on your custom cable for your In-Ear Monitors, headphones, or device(s). We have a compatibility list on the top of each "cables" page. You will see the company followed by the model the cables are compatible with. Select the company name of choice, unless specified.

Length: This option allows you to select the total length of the cable (plug to connector). You can select length up to 10 feet, however we are able to make shorter and longer cables (from 1 Feet to as long as 20 feet). You can contact us for pricing regarding lengths.

Wires: Select the wire/sound of choice. All of our wires are in transparent clear insulation, however you will also find some wires with different insulation colors and the option to combine two different wires and insulation colors for aesthetics and finding the ideal sound. If you have any trouble or need help with finding the sound that will best suit you, you can contact us.

Braid type: We offer different braid types depending on the series. All of them are for the most part straightforward. Round has a round appearance and is one of the most flexible. Flat has a flat appearance and is the smallest/thinnest braid. Semi-Round is a combination between round and flat with round top and flat bottom, Square braid has a square appearance and flexible.

Plug: Also known as termination, this is what you will be connecting your source with. We offer various (1/8",1/4") plugs, XLRs, RCAs, among others.

Lower Heatshrink: This is the heatshrink that is at the bottom of the cable.

Y-Splitter: This is the heat shrink tubing that is between the lower section and left/right split of the cable. Now offering y-splitters in cryo treated aluminum.

Slider: Also known as the chocker, it is the heat shrink (or aluminum) that is used to tighten up when worn for better fit and adjustability.

Left/Right Heatshrinks: Used to indicate the left or the right side on the connectors or you can match with the same color.

Lower Sleeving: This is the sleeving used from the bottom of the cable, up to the Y-splitter. Available in Black, Silver, and White. Option only available in Apollonian, Apollonian+, Echo, and Echo+ series.

Left/Right Sleeving: This is the sleeving used from the Y-Splitter, up to the connectors. We offer various 'noise reduction', nylon and techflex sleevings. Option only available in Dionysian, Echo, Echo+, LR, and LR+ Series.

Left/Right Braid: This is braid starting from the Y-Splitter, up to the connectors. We offer two types - Round, Flat, and Twist. Option only available in X6 and X8 series.
