ProStereo™ H1 Hi-Fidelity Wireless Headphone Amplifier and DAC: Sharing Perfect Sounds Without Limitation

20 July 2017

In addition to the ProStereo™ L5 stereo Bluetooth headset cable, i.Tech has released the H1 — a high-fidelity, 2-in-1 wireless headphone amplifier with USB DAC. The H1 distinguishes itself with its capability in Bluetooth transmission without compromising sound quality. The product ensures wireless music sharing and up-sampling to almost the quality of studio sound, offering a clear and stable Hi-Fi audio experience for users’ enjoyment.

Wireless Headphone Amplifier in Light-Weight Mini Clip Design

Unlike other general headphone amplifiers in the market, ProStereo™ H1 supports the Bluetooth version 4.2 and can be clipped easily onto a collar or a handbag. The use of Bluetooth minimizes the number of cables, allowing the pleasure of Hi-Fi audio with minimal weight burden. This completely transforms and enhances the portability of headphone amplifiers.

Bluetooth Transmission Without Compromising Sound Quality

With a maximum power output of up to 22.5mW + 22.5mW, ProStereo™ H1’s total harmonic distortion goes below 0.05%. It can easily match professional headsets with different levels of impedance and sensitivity. Besides, it produces clean and compelling sounds with a linear and high-frequency amplification effect. No matter which type of music file users play on their mobile phone or USB (MP3, AAC, FLAC, etc.), the audio data can be raised to up to a sampling rate of 32bit / 384kHz and be output to independent Hi-Fi DAC, making the digital waveform smoother and closer to the analog replay. With the support of aptX®& and AAC codec technology, H1 can deliver a penetrating sound with almost no reduction of quality, whether a user plays the music on an Android~ mobile phone or iPhone.

Real-Time Sharing of Playlist

ProStereo™ H1 made possible the real-time sharing of music in full integrity. Simply by using two sets of ProStereo™ H1s, users can share the songs in their playlist instantly with the aid of Bluetooth technology, thus enjoy the freedom of wireless sharing with friends and loved ones. Besides, the one-hour fast charge function allows sufficient power for music playback and handsfree calls.

Transforming into Professional USB DAC

In addition to wireless playback, ProStereo™ H1 also supports standard USB audio functions as an external USB DAC. Simply connect the USB data cable and external accessories supplied with the product directly to iOS^, Android~ device or computer audio source (CAS)=. With the built-in independent Hi-Fi DAC and amplifier chip by Texas Instruments to further reduce distortion and enhance music dynamics, it presents a truly enjoyable Hi-Fi sound experience.
