Topping NX1s Portable Headphone Amplifier (Silver/Black)
৳ 4,000Quick ViewExquisite Workmanship
We believe low pricing≠low quality. Aluminum shell of NX1s made by high-precision machining center, surface use same delicate treatment as MACBOOK, all character engraved with laser engraving. Even the small knobs are full of details.Compact & Portable
Small and excellent is the target of portable device. After all the above improvements, size of NX1s is only 75% of the previous NX1a and easier to carry with.Efficiently Durable
NX1s built-in 1000mAh battery. Due to the use of a reasonable high efficiency power supply design, NX1s can bring you up to 40 hours playback time. When the battery is low, the LED will turn red to remind you to change it in time.Quality Promise
NX1s has passed CE, ROHS and FCC certification. At the meanwhile NX1s exceed the requirements of Hi-Res Audio and got the authorized.Separate gain and mega
NX1s provide you low gain, which use for normal volume and give you less noise. NX1s provide you also high gain, which use for weak input and give you higher gain. In addition, you can select to mega bass to get powerful bass or select to close it to have clean and original sound.2 Claws
The knob will easily be mistakenly operated when you put a portable amplifier in your pocket. To avoid this problem, we designed two claws of NX1s. These claws not only make the knob no longer be mistakenly operated, they protect the headphone plugs not so easily be fractured.HIFI components
We have been through numerous of design and adjustment to determine a better sound for NX1s. We also use HIFI electronic component to improve sound quality.
