Operating at a minimum voltage of 2V, the system requires only 3mA of operating current, which is half the power consumption of a typical TWS IEM. However, the MA2430 boasts DAC capabilities for master tape-level music up to 192k and the performance of driving headphones with ultra-low distortion at 0.0002%, challenging the physical testing limits of current top-tier audio analyzers. 【Secure Fit】:The balance between comfort and sound quality is crucial yet often overlooked when it comes to in-ear headphone wear.During the early stages of NHB15 development, our designers collected data from extensive ear model databases, based on that, they made over 10 samples and created more than 50 models. Before the final design was confirmed, they had done lots of wear-comfort experiment with over 100 individuals covering different genders, ages, nationalities, and usage habits. This meticulous process took them 2 years to achieve the ultimate design.The included ear tips are interchangeable, providing a precisely tailored and comfortable wearing experience. 【Detachable Cable Design】:The NHB15 features a detachable cable design.
