For orders above ₹10,000 where a partial advance payment is collected:

  1. Order cancellation is allowed only within 24 hours of placing the order.
  2. After 24 hours, the advance amount will not be refunded, as procurement of the product is initiated immediately.

The Fosi Audio Q4 is a compact, entry-level desktop digital-to-analog converter (DAC) and headphone amplifier designed to eliminate the limitations of substandard internal computer soundcards. By converting digital audio signals from your personal computer, television, or gaming console into clean, high-fidelity analog sound, it elevates your entire listening experience. This mini stereo adapter is perfect for audiophiles, gamers, and desktop movie enthusiasts who want to unlock the true potential of their headphones and powered active speakers. Equipped with high-performance Texas Instruments NE5532 operational amplifier chips, it delivers exceptional low-noise performance, high output-drive capability, and minimal distortion. The front panel features a master volume control alongside independent bass and treble adjustment knobs, allowing you to fine-tune your audio profile to match your preferences. True plug-and-play functionality means there are no complex drivers or software installations needed for Windows, Mac, or Linux systems. Brought to you by Dropy India, this authentic USA-imported product provides an accessible yet powerful upgrade to your home studio or work-from-home entertainment setup.

Connect the digital audio source to the Fosi Audio Q4 via the included PC-USB, optical, or coaxial cable. Route the analog output by plugging your headphones into the front 3.5mm jack or connecting your powered speakers to the rear RCA outputs. Power the unit using the provided USB charging cable connected to a 5V power source. Set your source device's audio output format to stereo PCM, as Dolby or DTS signals are not supported. Turn the volume dial clockwise to power on and adjust the master volume, bass, and treble knobs to your preference.

FAQs

What headphones or speakers are you planning to connect?

The Fosi Audio Q4 is optimized to drive a wide variety of audio gear. The 3.5mm headphone output successfully powers headphones with an impedance rating between 16 Ohm and 200 Ohm. Meanwhile, the stereo RCA outputs on the rear panel are designed to connect directly to powered active desktop speakers or an external home stereo amplifier.

What inputs will you be using with this device?

This versatile digital-to-analog converter supports three primary digital inputs. You can use the PC-USB input for direct connection to laptops and computers running Windows, Mac, or Linux. The optical (Toslink) and coaxial S/PDIF inputs are perfect for fetching pristine audio signals from televisions, media streamers, or gaming consoles.

Does the Fosi Audio Q4 support microphone input for gaming headsets?

No, the Fosi Audio Q4 is strictly designed for high-fidelity audio output. The front-facing 3.5mm port functions exclusively as a headphone audio output and does not feature microphone line-in support. If you use a gaming headset with an attached microphone, you will need to connect the microphone plug directly to your computer's mic port.

Is this Fosi Audio Q4 an authentic product available in India?

Yes, absolutely. When you purchase from Dropy India, you are guaranteed a 100% authentic Fosi Audio product. We source our inventory directly from authorized channels in the USA and import them to India, ensuring Indian audiophiles get genuine international-grade personal care and electronic tech.

Why am I getting no sound when connecting my TV via optical cable?

If you hear no audio when using the optical or coaxial connections, check your television's sound settings menu. The Fosi Audio Q4 is a stereo DAC and does not decode multi-channel surround sound formats like Dolby Digital or DTS. You must change your TV or console's digital audio output format setting to Stereo or PCM for proper decoding.
