The Yaksha is a closed in-ear headphone from Celest Audio, built with both a standard 3.5mm unbalanced jack and a 4.4mm Pentaconn balanced connector. The dual-connector approach signals a design aimed at listeners who already own a source capable of balanced output, rather than a casual, phone-only in-ear.
Key specs that matter
The connector offers both unbalanced 3.5mm and balanced 4.4mm Pentaconn options, giving flexibility to match either a standard headphone output or a balanced source - a detail that matters mainly to listeners already invested in a balanced digital audio player or desktop amplifier, since a phone alone will not take advantage of the 4.4mm path.
Sound and use context
Expect the closed, isolating character typical of a sealed in-ear design, with the dual connector options accommodating both casual and higher-end sources - the acoustic design itself is unaffected by which cable is used, since the connector choice is purely about matching output level and noise floor to whatever source is available.
Pairing
The balanced 4.4mm connection benefits from a source offering balanced output; the 3.5mm option works with any standard headphone jack, so the in-ear scales with whatever the rest of the system already supports rather than mandating one particular source type.
Alternatives
In-ear headphones offering only a single connector type trade this flexibility for simplicity, which may suit a listener who has no interest in balanced sources and would rather not pay for a feature they will never use. Celest Audio's catalogue centres on in-ear designs at this general price and connector tier, competing in a crowded space where many similarly specified in-ears exist from other boutique brands. The dual 3.5mm and 4.4mm termination is becoming more common across this segment, driven by the growing number of portable players and phones now offering balanced headphone outputs as standard rather than a premium feature. As with most in-ear designs at this tier, eartip selection has an outsized effect on the final perceived bass response and seal, often more so than any circuit-level design choice inside the earpiece itself. Cable quality on in-ears at this connector tier tends to matter less for tonal balance than for durability and microphonics, so a listener unhappy with the stock cable can often improve the practical experience with an aftermarket replacement rather than needing a different earphone entirely
