iBasso - DC03

This little thing works great. While the consumer grade in-ears worked fine, the difference is notable on a headphone. While most of the time this will be connected to a PC, I'm sharing my observations with my OnePlus 7T.

Test setup 1:
Phone: OnePlus 7T
Headphone: Edifier W820BT (connected via wires)
DAC: iBasso DC03
Music Player: HiByMusic

This player can gain direct access to this DAC, hence audio quality is unaltered. And those flacs sound fantastic with all the details you need to hear.
Drawback of this setup - Can't use equalizer

Test Setup 2:
Same hardware
Music Player: Spotify (Highest quality available)
Equalizer: PowerAmp Equalizer
Bass Gain: 60%
Treble Gain: 15%

Audio from Spotify + PowerAmp Equalizer sounds good as well. I don't know what the DC03 is doing, but those bass hits hard now! It's like I have a brand new pair of some Bass heavy headphones.

Note for Android Users - Audio routed through Android's own system resamples everything to 48kHz. This should not affect Spotify which should be either 44.1kHz or 48kHz, but choose your Music Player for your files wisely.

Regards.

Very tiny item, slightly getting warm that means something is working inside obliviously battery consumption increased when connected to mobile. I am totally satisfied with this price range.

Hello Raghav,
I was initially satisfied with the output. But I was so unhappy as it started delivering its output. The indicator light provided on DAC is not blinking. I need replacement of the product ASAP

I purchased this dac with kz zsn pro X. Can totally hear the difference using Apple music hi res audio. Instruments and vocals are sharp and the bass is right although treble being sharp can be tuned in eq settings. Better music and instrument seperation.
Would suggest to go for this if you're into hi res audio and ibasso also supports mic as well unlike shangling dacs.

iBasso - DC03

Using the DC03 along with my Blon BL-03; I am able to hear a lil bit more detail, can hear improvements in bass and 50%-60% volume with the DC03 is as loud as 80-90% without it.

Fantastic product.

Using this Dac/ Amp definitely makes a noticeable difference and that too this is when I checked it with a basic earphones. The difference that I found is primarily in Bass and treble definition, especially the bass quality increases both in terms of volume and definition, treble definition also increases slightly and midrange is neither boosted nor suppressed. I also used it it with full sized headphones (Sony MDR 7506) it sounded pretty good. I somehow feel that the dac performs much better while using with IEM's rather than headphones. The one thing that I noticed is that the Dac gets warm while using it for sometime and then it gets normal.

Awaiting replacement

Exceptional sound quality.
This tiny DAC enhances sounds to next level and worth every penny you spent on this DAC. Only con is we can't control volume or skip track using inline buttons and it heats up on long hours usage..

Superb performance! Enjoying it to the fullest. It makes the sound fuller and bolder. Go for it.
