Rather strangely when I first got my e18 I got a lot of interference with my Note 3. I hardly notice it anymore, I can't say for sure whether it has improved or whether I've just got used to it. Needless to say it doesn't bother me and I'd definitely still recommend the e18.

Thanks for the endorsement.  I am sensitive to EMI and I would picture it being an issue I cannot overlook.

I seem to remember people at the time suggesting ferrite beads or tin foil in between the devices or something. The most effective method is not placing them on top of each other but as I said I can't recall it happening recently. It may have been an issue with more sensitive iems as I mainly use it with full size cans these days. It may also have been resolved in an update to Android of which there have been several.

I have the same phone on the same network. I experience this, even without wifi, when the phone does a digital cellular access. If I don't sandwich the phone I don't get this problem. It's far less with the Note 3 than I had previously with my GS3.

I would most likely need to sandwich them for use with the aux in for my car stereo.  I appreciate the feedback of people with similar setups.

Cables arrived today and work perfectly. The cables a bit stiff and doesnt really like being folded in half but a massive improvement over the originals and I actually feel confident that it won't damage my phones usb port if I carry it in my pocket out of the house unlike the downward facing cables bundled with the amp. Cheers for the link man and I can thoroughly recommend these cables to anyone else looking for an angled micro usb cable.

Glad it worked out. Enjoy!

Hello. I have noticed a fair amount of people having interference issues with the E18 and their phone but I have an issue with interference and my laptop. I have the E18 paired with my laptop as a DAC and then through a pair of Audioengine A5+. All is good until I decide to change wifi network then I get lots of crackling and the music stops and starts skipping track after track. Im wondering if this is an interference issue with the wifi or a driver problem? Any suggestions would be gratefully welcomed.

Ferrite clamps on your (USB) wires can help.

Alternatively, try setting your WiFi router manually to another channel and test different channels (and disable modes you do not use, ex. a/b; leave only the 5Mhz band active).

 

 

 

Why can one have interference?

Any wire is an antenna. The radio waves will try to find the first/best conductor they can find, so that will be your computers wires, motherboard, the E18 electronics, etc. This is nature and nothing can be done ... but ferrite clamps and/or shielding devices/wires.

Shielding can be around the computer/device and/or the ferrite clamps around the wires (USB, power, ...).

I hope this can help.

 

 

With kind regards,

Casper thanks for the info. I will get myself some ferrite clamps next. Tried very basic shielding earlier by wrapping the E18 in tin foil but that made no difference. Also switched the router to 5GHZ but no joy. Fingers crossed the clamps help.

Casper do you think my issue is actually interference. I say this because when playing music normally everything is absolutely fine. Its only when I select the wifi icon on the task bar that I get the cracking and popping noise. The minute I close the wifi settings on the task bar everything goes back to normal. This issue seems to point more to a driver problem as if it was interference surely it would happen more randomly and not at the exact time of opening the settings.

Hmmm, very strange ... you could be correct.

 

I hope i did not send you into costs ...  

And I hope you can solve the issue and let us know. We can all learn from any experience.

 

With kind regards,

Casper lol no I have not bought anything yet. No chance as working in Saudi Arabia and not really spoilt for choice when it comes to electronics. Anyway I have narrowed the problem down to drivers 100%. Have installed Windows 10 as a second operating system and the problem has gone. Reboot into Windows 8.1 and the problem returns. The only option I have at the minute is to try and extract the USB audio driver from 10 and install it on 8. Will keep you posted if I get it sorted out.

:-)    Great!  And ... with Win 10 you're all set.
