Review on 🎧 Syba USB 2.0 24 bit 96KHz DAC and Headphone Amplifier with EQ Bass Boost – Compatible with Windows, MacOS, Linux, Android, PS3, PS4 by David Guerrero

Very small. Attractive design. Windows 10 Pro and Home automatically detect and configure it on my desktop and laptop. The rotary volume control has a nice, weighted feel when rotated and adjusts headphone and line-out output levels. The headphone amplifier has sufficient power (capable of delivering very loud volumes with both Etymotic Hf5 16 ohm headphones and Shure SRH144 32 ohm headphones). The sound output when connected to the USB outputs of my desktop monitor was overshadowed by pops and crackles, but apparently this is due to the instability of the power supply to the USB hub outputs. Connecting the device to the USB output on the front of the system unit, which connects directly to the motherboard connector, solved the noise problem. This is a limitation of all USB powered audio devices and is not an inherent problem with this product. The allowable sound adjustments (treble boost or bass boost) are not subtle, but can be close to correct for playback devices that exhibit a distinct lack of high or low frequency response. I've only had this product for a day, but it seems to work exactly as intended and advertised, and it solves problems I've had with my laptop's headphone output and desktop computer monitor's soundbar - output too low for some sources and not linear (lack of bass) output behavior.
