Choose the right ABYSS headphone adaptor cable for your setup. Compare XLR, 4.4mm, and 6.3mm terminations and find your fit.
Quick Answer
Your choice of ABYSS headphone adaptor cable comes down to the connector on your amplifier and the termination on your headphone cable. Match the adaptor to bridge the two.
Why the Adaptor Matters for Sound Quality
The adaptor cable is not just a passive bridge — its construction affects signal integrity. JPS Labs, known for high-performance audio cables, builds these adaptors with the same cabling used on the ABYSS AB-1266 headphones. That means you get consistent conductor quality regardless of the termination you choose.
Because the adaptor is only about 6 inches (15 cm) long, it adds minimal cable length to your path. This keeps capacitance and resistance low, preserving the original tonal balance of your headphone and amplifier pairing.
XLR vs 4.4mm vs 6.3mm: The Core Trade-Offs
XLR (balanced) connections are common on high-end desktop amplifiers and offer the best noise rejection over longer runs. However, they require a balanced output from your amp and a balanced headphone cable. A 4.4mm Pentaconn connector is a compact balanced option found on many portable DAC/amps and some desktop units, but it is less common on legacy gear. A 6.3mm (1/4 inch) single-ended connector is the most universal — almost every headphone amplifier has one — but it does not provide the common-mode noise rejection of balanced connections.
If your amplifier lacks a balanced output, using an XLR or 4.4mm adaptor gains you nothing electrically. Conversely, if your amplifier has a balanced output and your headphone cable is terminated with a 6.3mm plug, you are leaving potential channel separation and noise rejection on the table. The adaptor simply converts the physical connector; it cannot change the signal topology of your amp.
How to Choose Your Adaptor
- XLR Adaptor: Use if both your amplifier and headphone cable support balanced operation. Ideal for desktop setups with XLR outputs. Trade-off: not compatible with single-ended-only amps or portable gear without an XLR port.
- 4.4mm Pentaconn Adaptor: Best for portable DAC/amps and newer desktop units with a 4.4mm balanced output. Trade-off: less common on older or budget amplifiers; requires a balanced headphone cable to benefit.
- 6.3mm (1/4") Adaptor: The universal fallback. Works with nearly any headphone amplifier. Trade-off: single-ended connection only; does not provide the noise rejection or channel separation of a balanced path. If you are unsure about your amp's output type, start with a 6.3mm adaptor and upgrade later if your gear supports balanced.
Product Facts

Which Adaptor Fits Your Setup?
Best for
- Listeners with a balanced desktop amplifier and a balanced headphone cable who want to preserve full channel separation and noise rejection.
- Portable users with a 4.4mm output who need a compact balanced connection.
Not for
- Anyone whose amplifier only has a 6.3mm single-ended output — an XLR or 4.4mm adaptor would add no sonic benefit.
- Users who want to convert a single-ended headphone cable to balanced; the adaptor cannot change the cable's wiring topology.
