Compare the 64 Audio Copper and Pearl Eight-Braid cables: impedance, build, and connector options. Find out which upgrade suits your IEM setup.
Quick answer
Choose the Copper Eight-Braid Cable if you prioritize low impedance and a balanced 4.4mm option. Choose the Pearl Eight-Braid Cable if you want a comfortable, ergonomic fit with 2-Pin connectors and a softer jacket.
What sets these cables apart
Both cables are eight-braid designs from 64 Audio, but they target different preferences. The Copper cable is engineered for pure copper conductivity and offers both 3.5mm single-ended and 4.4mm balanced connectors. The Pearl cable, originally released with the U18s, focuses on comfort with its soft touch jacketing and ergonomic curve around the ear.
The choice often comes down to connector type and fit. If your IEM or source supports balanced output, the Copper cable's 4.4mm option may be a deciding factor. If you prefer a memory-wire-free fit that hugs the ear naturally, the Pearl cable's design is worth considering.
Trade-offs at a glance
- Connector flexibility: The Copper cable offers both 3.5mm and 4.4mm options. The Pearl cable is fixed with 2-Pin connectors. If you need balanced output, the Copper cable is the clear choice. Check your source's output before deciding.
- Comfort and fit: The Pearl cable's ergonomic curve and soft touch jacketing eliminate the need for a memory wire, which may be more comfortable for extended listening. The Copper cable has a functional aluminum cinch for a secure fit. If you wear your IEMs for long sessions, prioritize the Pearl's ergonomic design.
- Electrical performance: The Copper cable's 0.26Ω impedance is impressively low, which may appeal to those who want to minimize any potential impact on sound. The Pearl cable's impedance is not specified, so it's a trade-off if you're chasing specs. If low impedance is critical, choose Copper; otherwise, the Pearl's comfort may outweigh the unknown.
Product facts
- Pearl Eight-Braid Cable: The Pearl Eight-Braid Cable features branded aluminum bifurcation, soft touch jacketing, and angled 2-Pin connectors at the end of an ergonomic curve for a comfortable fit without a memory wire. This design suits listeners who prioritize long-wearing comfort and a secure, natural fit around the ear.
Pearl Eight-Braid Cable - Copper Eight-Braid Cable: The Copper Eight-Braid Cable uses OCC Copper (23 x 25 AWG wires) braided into eight strands, with a low 0.26Ω impedance rating and available 3.5mm single-ended or 4.4mm balanced connectors. The low impedance and balanced option make it a strong choice for those seeking minimal signal loss and compatibility with balanced sources.
