Only if you use the balanced output. Here's what the first Head-Fi reviewer wrote: "Power output from the balanced output is enough to drive a lot of headphones like the HD660S albeit with the Clear Mg something was left to be desired." If the unbalanced output (125mw at 32 ohms) could drive...

I have not heard that glitch noise. Yes, the FC3 works with the Hiby app. I don't use the app because all of my music is through Amazon music.

Good find. Thanks! The dual 9038 and dual amps intrigue me. But it's sad that the power for unbalanced mode his barely inched, from 70 mw to 85. And I guess I would have preferred a standard dongle form factor for inline use.

Absolutely. Check out this site's raves: https://www.hypethesonics.com/hiby-fc3-minihype/

It's time I weighed in with my short impressions. I'll begin with a comment I shared under a YouTube review: "I'm am amazed by my HiBy FC3, using 32-ohm closed headphones. The definition is incredible. In the Sonata line-up, the closest competitor is the E35, which was introduced in the first...

I've created this Google Docs spreadsheet to capture the specs of all DAC-amp dongles that are USB-powered, provide at least 60mW per channel of unbalanced (3.5, single-ended) output at 32 ohms, and have physical controls. I know I'm not alone in favoring physical controls, and I hope this...

Are you using a headphone cable that supports a microphone? If so, that could be the problem.

PM sent to buy the black one!

I own the FC3 and an LG V20. You need two cables in a chain: 1. USB-C male to USB-A male, and 2. USB-A female to USB-C male OTG (On the Go) dongle to join the first cable to your V20.

I solved my FC3's conne, too, couldn't get my FC3 to work at its full potential when connected to LG V20 phone.

The top-of-the-line Sabre 9281pro DAC can be found in only five DAC+amps: Audirect Beam 2S, Earmen Sparrow, Hiby FC3, THX Onyx, and Zorloo Ztella. Of the five, only the Audirect and Hiby provide physical volume controls. And of those two, only the Hiby lets you use your unbalalanced headphones.

According to this page, the Questyle M22 has just 27mW per channel at 32 ohms. That's one-third the power of the HIBY FC3.

It's too bad these don't have built-in hardware volume controls. I was just shopping for a USB-C amp+DAC with a 3.5mm unbalanced output and more than 60mW per channel at 32 ohms. Extra points if it didn't rely on micro USB. I narrowed my list to these, listed alphabetically: Hiby FC3 Hidizs...

I have a small investment in premium AKG-type cables that connect to the headphone by a mini-XLR plug. Also, premium mini-to-mini cables (3.5mm to 3.5mm). Are you saying that the K450 uses a different kind of plug?

Other than cans from AKG and Sennheiser, which closed phones have a cable that can be replaced by simply unplugging the old one and plugging in a new? I'm considering the AKG ATHM40FS (ATH M40FS) for commuting, but even though it's said to have a "field-replaceable" cable, nowhere can I find...

At home and at work, I use the same setup: AKG K271S, driven by a MarkIV. Trust me, regardless of the modest ohms listed in its specs, the K271S (and K271 Mark II) need a decent amount of power to sound like a premium phone. A USB1 won't cut it. Quote: Originally Posted by Shimmer...

AKGs, yes; K-271 or K-272, no; without an amp, you give up too much in dynanics (response), even if you could drive them loud enough. Look no further than the ulber-cheap K-81 or its many-colored successor, the K-518. The 518 special edition (limited edition?) comes with a shorter cord...

Check out my thread in the Cables forum about a 14-inch short cable that converts mini-XLR AKGs to use a mini plug or mini jack.

article and photos here.

Three of my phones are AKGs whose cable requires a mini-XLR connector. Dismayed by the high prices of premium aftermarket cables for AKGs, I searched for a high-quality adapter that would let me attach a standard mini-to-mini (3.5mm-to-3.5mm) stereo interconnect cable. In this way, I could...

At home and at work, I run a MarkIV through a 7-port powered USB hub...not to extend the distance, but rather to free up a USB port on my computer or dock. Regarding powered speakers: At home, my M-Audio DX4s have responded with greater clarity and volume. At work, my M-Audio StudioPro 3s are...

Dave, My second Mark IV arrived today. Unlike the first, it includes a second 3.5mm minijack--this one on the rear panel, beside the USB port! This rear minijack is neither shown nor mentioned in the user instructions that came with either Mark IV. Is it an Line In input? Or a third output...
