The NHB15 features a USB Type-C connector fully compatible with the latest iPhone 15 series, iPads running iOS, Android, Samsung Galaxy, HarmonyOS smartphones, as well as computers using Windows and macOS. With plug-and-play functionality, no drivers or settings adjustments are required, making it easy to experience true lossless audio wherever you are.
When NHB15 is running and processing audio data with a sample rate of 48k or below, an indicator will light up.
When NHB15 processes high-resolution lossless data which are higher than 48k, the two indicators will light up.
Questyle Technology, in collaboration with strategic partner USI (Universal Scientific Industrial), embarked on a two-year journey starting in 2021 to develop a series of chips, including the audio SiP chip MA2430, all in the pursuit of an uncompromising auditory experience. The MA2430 incorporates the Current Mode amplifier and the entire chain of lossless audio signal processing. 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.

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.
The NHB15 features a detachable cable design. What is more, we provide a classic 3.5mm cable included in the box. The interchangeable cable can be paired with various devices.
The NHB15 comes with a specially designed headphone storage pouch, compact in size similar to a car key, making it convenient to carry in your pocket for on-the-go use.
