Description

【Compatibility】:The type-C is fully compatible with the entire iPhone 15 series, iPads running on the iOS system, Android and HarmonyOS smartphones as well as computers operating on Windows and macOS systems. As a result, users can enjoy true lossless music across a broad spectrum of smart devices.

【 HiFi Stereo Sound】:Continuing Questyle’s expertise in True Lossless Audio, equipped with the patented Current Mode Amplifier SiP, paired with 192k lossless music for smartphones, the NHB15 makes traditional audio devices obsolete and offers a plug-and-play experience.

【SiP Chip for Independent DAC and Amp: MA2430】: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.

【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. What is more, we provide a classic 3.5mm cable included in the box. The interchangeable cable can be paired with various devices.

【What You Get】:NHB15 comes with 1* USB C Hi-Res lossless earphones,1*3.5mm cable,5 pairs of silicone ear tips,1*leather case,1*manual&warranty card.Lifetime friendly customer service for QUESTYLE headphones. Any question, pls contact us any time, we'll response you within 24hrs on weekdays.

Common questions about buying open-box and refurbished.

Why buy refurbished or open-box?

Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $395 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.

What's the difference between open-box and refurbished?

Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.

Why use OpenBoxFox?

Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for Questyle products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.

Is it safe to buy refurbished?

Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
