Instead of discovering solid sound and calling it a day, HiSound Audio packed the rest of the construction with high quality components. It starts with using red rosewood from Africa as the casing, injecting stunning good looks into your ears and avoiding the pitfalls of plain plastic. For the cable, you have your choice of a tangle-free round cable or a flat cable with an in-line microphone and remote. To bring it all together, every high stress area has rigid plastic joints, ensuring the longevity of your IEMs. Including a range of silicone tips so you can find the perfect isolation, the HiSound Audio WooDuo 2 IEMs look, sound, and feel like a breath of fresh air.
