Bolton Technical SIVGA SV021 Pro
The Bolton Technical SIVGA SV021 Pro is a wired over-ear headphone built around a 50 mm dynamic driver. It targets listeners who want high-fidelity sound from a closed-back wooden design. The detachable cable ends in a 3.5 mm plug for broad device compatibility. It suits home or office use where a wired connection is preferred.
Closed-back wooden cups and 3.5 mm wired link
The closed-back wooden ear cups reduce sound leakage and block outside noise for private listening. A 3.5 mm analogue connection means audio quality depends on the source device’s built-in DAC and amplifier. No wireless codec, battery or digital processing is involved, so latency is not a factor. The cable length is fixed by the supplied lead.
Real wood, metal frame and detachable cable
Ear cups are crafted from real wood with a reinforced metal frame for structural rigidity. Soft ergonomic pads and an adjustable headband distribute weight for long sessions. The detachable cable allows straightforward replacement or upgrade without soldering. Wood surfaces need occasional care to maintain finish and prevent drying.
