Warning: 9038D contains a high-sensitive I/V stage that may cause audible noise when your phone uses LTE 4G, 5g.


i saw this on their website. Is this really make so much noise cause I use it mainly on the street using 4g LTE?

I put my phone on airplane mode when I'm listening with the E1DA. It's healthier, too when you carry your phone close to your body.

PDV21 user here, but at least with my older android 7 smarthpone and I don't notice any 4G related noises, fwiw. that includes listening while using my mobile as a hotspot. In fact my mobile has quite a bit less noise than when connected to my laptop.

According to the site whose link you shared AKG K240 sextett can reach 102dB with 9038D. Isn't it more than enough? I used 92db SPL /mW.
indeed the sensitivity is a big factor. beyerdynamic's dt880 600 ohm is rated at 96 db/mw for example, which requires more juice.

92 db SPL is pretty loud. but keep in mind these are just quantitative pressure levels measured at these figures. With the weaker amp you're missing out probably in bass response, imaging, and all the other qualitative superlatives depending on the actual headphone. I don't think the sextett has a lot of bass in it to begin with so I reckon you might be fine with it.

just got the 9038D 2days ago, pure sq alone, this device is mindblowing but the only downside is the inteference, buzzing noise with LTE and 2G (text message / SMS) 🥲also somehow the buzzing and beeping noise when 2G is activated or receiving text message is louder on the left channel

no interferences with 3G and Wifi

i previously own the 9038s G3 and somehow prefer the sound of the 9038D, the 9038D to me sounds more airy and the overall presentation is spacier and wider.

Hmm, it will be so inconvenient when you want to listen to music and go to the internet at the same time?🤨
I don't listen to music as a background sound. Either I'm on the internet or enjoying my music. If you use a dedicated player like Neutron it cancels all notifications by the phone anyway. But the radiation is still there if you are not on airplane mode.

How is the sq between 9038s(110$) and powerdac 2.1? (70$). Worth it difference?

Not sure about SQ, but I got the powerdac to have access to the HPToy companion app, which is great. This doesn't work with the 9038. The form factor and heat exclude it from being very portable. I use it attached to my phone while seated but I don't think it'd work too well on-the-go. 9038 looks way better depending on your uses.

The SQ on PowerDAC has converted me to a big fan of E1DA. I will get 9038 next year to try out.

>>It picks up a huge amount of interference when using mobile data.

maybe this get to be solved
Warning: 9038D contains a high-sensitive I/V stage that may cause audible noise when your phone uses LTE 4G, 5g. Some newest hardware may have issues like "stuttering" with USB3(Macbook pro 2020, MS Sufrrase 2020, Lenovo Carbone 2020, Acer SF313-52-71Y7 2020). USB audio-bridge manufacturer was informed about that and we expecting the FW solution.

Interested in this. I have an S9 Pro (ESS9038Q2M, correct?) and while it works well in most situations, when playing back native DSD files on an HP Spectre x360 (2019, USB 3 ports)) it stutters and skips. Though on a MacBook Pro 14' (M1) and my Samsung Note 20 Ultra, the same files play fine.

OK!
Got Tweak9038 app pro version and now I can see DAC presets, though may need to read about them and test them out. I have 9038D that has 3.5 mm out only. Will try to play around with this app.

PowerDac v2.1 can be controlled by HPToy app and has 2.5 mm bal out output (comes with 2.5 to 3.5 mm adapter).
The DAC mode on the 9038D is simply presets for different rates and bit depths, etc and saved. The amp is always active on the 9038D, regardless of the setting in the app.

I have never heard any noise when using my phones, either 4G or 5G. Never.
