What makes a great entry-level IEM cable?
A sensible first cable purchase should fit your earphones, connect to your player, and stay within your budget. BlackMamba and PRISMNOIR put those basics first, with two different copper conductor options at the same approachable price.
We are offering these two cables with two different cores, as you deserves choices.
YONGSE BlackMamba
Single crystal copper. A straightforward starting point.
BlackMamba features high-purity single crystal copper conductors, a 4.4mm balanced plug, and 0.78mm recessed 2-pin connectors. Its approximately 1.2-metre length suits a portable listening setup without the extra reach of a long desktop cable.

Choose BlackMamba if you want to try a single crystal copper cable without committing to a premium cable budget.
US$9.99
YONGSE PRISMNOIR
Japan quality - Furukawa oxygen-free copper. The same accessible price.
PRISMNOIR features high-purity Furukawa oxygen-free copper conductors, paired with a 4.4mm balanced plug and 0.78mm recessed 2-pin connectors. At approximately 1.2 metres, it offers the same practical length as BlackMamba.
Choose PRISMNOIR if you are interested in Furukawa OFC construction for your first aftermarket IEM cable.

US$9.99
BlackMamba or PRISMNOIR?
Choose by conductor preference, not by price. BlackMamba uses high-purity single crystal copper; PRISMNOIR uses high-purity Furukawa oxygen-free copper. Both are currently US$9.99, with 4.4mm balanced termination, 0.78mm recessed 2-pin connectors, and approximately 1.2-metre length.
Neither needs to be a complicated decision. Check compatibility first, then pick the construction that interests you most.
Before you buy: check both ends
Your earphones: confirm that they accept 0.78mm 2-pin cables and that the connector housing fits their sockets. These listed variants are recessed 2-pin, not MMCX. Do not assume every 2-pin earphone uses the same socket design.
Your source: both listed variants use a 4.4mm balanced plug. You need a compatible 4.4mm balanced headphone output on your DAC, amplifier, or player. These plugs do not connect directly to a standard 3.5mm headphone socket.
Frequently asked questions (Q&A)
Will a cable transform the sound of my IEMs?
A cable is not a guaranteed sound upgrade. Audible results depend on the earphones, source, and electrical characteristics of the complete setup. Buy for compatibility, construction, and your own preferences rather than expecting a dramatic change in bass, detail, or soundstage.
Which is the best entry-level cable for me?
The best choice is the one that fits your equipment and budget. If your setup supports these connectors, BlackMamba and PRISMNOIR offer two copper options at the same US$9.99 starting price.
Do I need to buy both?
Choose one that suits your preferences and compatible equipment. A first cable upgrade should keep things simple. Or if you want to test if you can hear difference, or get cables for multiple IEMs, take your chance to enjoy this discount!
