Let your enjoyment commence, Making the "sound" in "sound quality"
In order to ensure the signals between your source and your earphones are purely and reliably sent, the BL44 uses high-purity annealed single crystal copper for its wire material. This ensures excellent frequency response and especially clear and exquisite vocals for an upgrade you can't help but hear.
Emphasis on "premium" in "premium materials"
Compared to your typical adapter, the BL44 uses more high-end material in both the wiring and connectors, resulting in a sound with timbre that sounds noticeably more refined. With high quality HPC-23T annealed high-purity single crystal copper wire manufactured by Oyaide Electric of Japan wrapped in a TPE skin, all constructed with excellent workmanship, the BL44 exudes quality both in sound and looks. In addition, the 4.4mm and 2.5mm plugs on the ends of the cable are made of copper plated material and an aluminum alloy mix, for a smooth feel that captures the attention of onlookers.
The advantage of being short
The BL44 is only 8cm long (not including the connectors on either side). Combined with the added strength of double twisted wires, the BL44's short length ensures your wire won't unnecessarily catch on surfaces and break, while bring you closer to your music than ever.
The BL44 is suitable for when one wants to use their 2.5mm balanced-terminated earphones with a device that accepts 4.4mm balanced-terminated earphones, such as various Sony players or FiiO products with the AM3B amplifier module.
