Today I received an A306 from Bic Camera (via buyee) which does not have the bass issue, confirmed via REW. It sounds dramatically better, and tests perfectly flat. The only issue is that the screen has several stuck pixels that persist even through multiple reboots and runs of a pixel...

For those wondering if only the DAC is affected, unfortunately that's not the case. I got the same results in the W app, the music player from the Files app, and Plexamp.

Alright so I think I figured out REW enough to do this correctly, and it definitely looks like my A306 is having trouble with lower frequencies. The orange line is from the Apple USB C Headphone Adapter plugged into the A306, and the blue line is from the A306 in direct mode without any DSP...

Nope, all via the headphone jack. Returning is an option (albeit a painful one given I imported it from Japan), but I think I want to try with an easier to drive set of headphones before declaring it mechanically defective. Either that or get a scientific confirmation that some models exhibit...

S01-20002xx After trying a few different listening devices (WH-1000XM3 via passive, Mackie CR3, Apple EarPods) I'm starting to think the issue is related to power output. I've only been able to reproduce the flat sound via my DT 770 PRO. I wouldn't have anticipated that the Japanese A300 would...

Just got my A306 today from Japan and wanted to share a few things I've discovered, as well as provide another example of a lack of low-end. First, for those of you not familiar with Android, there are three types of navigation bar (the three symbols on the bottom of the screen). The A300 ships...
