Product Description

HIFI Headphone Amplifier Headset Audio AMP USB Interface 120mW Output A935

Features:
There are so many headphone amplifiers available in the market, why choose us?
– Upgraded sound quality: top sound quality, let time prove everything, make sound transparent, awaken music inspiration, the new design concept, more than imagination, three-partition isolation circuit, master power, two operational amplifier sets (OPA2604AP+OPA2107AP) provided by US Famous BB, treble/bass is felt to significantly upgrade one level after multi-operational serially connecting to the product, which is benefited from the internal ±7.5V high voltage for greatly enhancing the thrust.

– Details reproduction: The product can capture more details which are not the extra addition to product but the existing ones, because non-professional headphone amplifier often disposes such details.

– Increased sound field: Anyone who doesn’t use a good headphone amplifier may never better understand “sound fieldâ€, it is a sense of presence, the sense of scene heard from a transductive headphone is different from that added to the product, it is worth noting that a good headphone amplifier deserves a good headset.

– Backup cellphone power: The unique product design (cellphone charging) can be used as the backup power.

Description:
Prefer sound quality, seek reproduction, multi-operational serial thrust, A935 selects two operational amplifier sets (OPA2604AP+OPA2107) featuring good sound quality and large thrust provided by American famous BB, with superb effect, the small-sized distinct dual-power boosted circuit carefully researched by engineer upgrades the transparency of OPA2604 to the highest grade of amplification effect. Power is the key to producing good sound from the portable headphone amplifier, and A935 power supply adopts the complex and costly dual-power design. Among so many single-power headphone amplifiers available in the market, A933 high-quality high-current positive-negative power supply is absolutely considered as the “master gradeâ€. Through partitioning, headphone amplification is kept far away from the power supply to solve the possible electromagnetic interference caused by power boost.

Ultra-small-sized audio filter capacitor array + LC type filter circuit reduce the system ripple to the minimum, providing clean and high transient power to the headphone amplification circuit.

As a headphone amplifier with the strongest sound quality, A935 is featured by high SNR, delicate and transparent sound quality and large thrust. Headphone fans are often experienced that, although headphone is the nearest acoustic device to human ears, even the distance from common in-ear buds to the eardrum is only 1-2 cm, in most cases, the sound is heard to be obscure, as if the glass cannot be properly cleaned, it sounds a bit unclear, A933 will free you from this concern.

This product uses quadruplex potentiometer to regulate the volume, the power switch is provided by Japan ALPS, the power relay is provided by Japan to offer dual protection on the output circuit, prevent impact sound and protect the headphone. Its power supply is added with the unique charging feature, which can charge other intelligent devices and output 1A current.

About burn-in: Our intended design effect is only achieved after burning-in the product for some time. For headphone and speaker: need to burn-in for 96 hours; for amplifier and other devices: need to burn-in for 24 hours, burn-in mode: select the continuous burn-in or the cumulative regular use.
