post #916 of 933

Hello guys. Does anyone know why when I plug in my earphones into the 3.5mm jack of the Pico Slim I hear some static noise?

Also, sometimes I need to turn the jack while it's plugged in, since the sound is extremely muffled and no bass can be heard. Sometimes, I only hear sound from one earpiece.

This all goes away after the jack stays inside the Pico for about 10 minutes or so. Any idea on why this happens and how it can be fixed? Please let me know, since it's been driving me crazy.

Hi and happy new year to all.

I bought this little amp and I must say I am surprised by the power that comes out of a machine of this size ! :basshead:

 

I would be talking more but for now I'm delighted with my purchase!

 

I would like to test other amps (see DAC) to compare. Some were able to compare it  pico slim with the Oppo HA2 for example? Or Cayin C5 (he seems to have good press this one!) :confused:

 

I'm also going to ask the question on each of these two amps forum ;)

It's so good to read that Justin's little gem is still very much on the front pages of the portable amp forum.  So deserving.  I have had mine ever since they Pico Slim came out and it's been with me all over the world, but mostly in the gym with my iMod!  Actually, one of the sound features I have found amazing with the Pico Slim is the stereo width and separation (playing mostly classical lossless).  Maybe not so much all around sound, but some real right/left definition and calrity.  So, sorry to disagree - respectfully - but my experience is different in terms of "stage width".

 

As much as this little amp has travelled and been knocking around in my short's pocket, other than a little bit of wear on the charging port, this champ has held up and worked flawlessly.  Testament to Justin's remarkable talents.

It's great isn't it? 

 

I must've got my chrome coloured first edition one about the same time as you.  Love it lots with my Sennheiser HD25/Amperior set up for running.   Works great for the Beyerdynamic T5ps - shockingly well!  The leatherette case is a bit battered but the little amp is so sweet!

 

Have to say, it's a bit mismatched with Ultrasone Pro900s which have a higher Ohm rating around 40, compared to 32 of the Senns.  They drive 32s comfortably but the Ultrasones, particularly for 1970's recorded classical music, I'm hearing more extraneous outside noise even at full volume for source mini-disc and amp.   

 

In ears are prob better than large overhead/circumaurals with higher impedances, but I've only tried it with the Sennheiser IE8s.  

 

Such a well designed micro portable amp!

That's ok, you have the right to have a different opinion than mine. After, may be it is due to my source (a Galaxy S5).

But that does not enpêche me to love and use every day

I don't own a Pico Slim, but my guess is that the headphone jack is getting worn out and is not always making good contact with the plug on your headphone. Maybe you can get the Jack replaced. Maybe you can go directly to the Headamp site and ask if you can send it in for repair.

In fact, that's strange ! I dont think about a problem with the headphone jack, because the static noise as no reason to go away after somes minutes ? I think about intern electronics maybe ? But mzybe i'm wrong

Hello Jedaite 

 

So, what news with you problem? It is resolved, you sent your Pico Slim repair or you do "with" :confused_face_2:

Hey there, there's been no resolution for my problem. The static discharge when you plug in your eaprhones into the amp is normal from what I've read here and Justin (from HeadAmp, the guy who makes these) said it's normal, but that's all I remember. Idk what causes this static discharge issue, but it's a shame it's present in a $400 amp. As for the sound artifacts (missing bass, and other artifacts I have no knowledge or words to explain) it happened even with a new cable.

 

I just need to wiggle the cable a bit while it's inserted into the amp to fix the issue. This rarely happens now with my new Linum cable, (which features a straight 3.5mm jack), but I do have to wonder why it happens in the first place. I e-mailed Justin about it several weeks ago, but got no response. It's not an end-game issue or a deal breaker, but in some cases, especially if you have a right angle 3.5mm jack (like I did) it can easily get very annoying to keep wiggling the cable while it's inserted into the amp.

Ok, I hope you will find a solution.

 

To the right jack rather than angled jack,, I am not surprised because with the right jack, you will be less likely to hang the jack and thus create a problem.

Thanks, I'm not running into these issues anymore with the new Linum Bax cable but on extremely rare occasions. So it's all good at the moment :)

Ok, enjoy now :)

Thanks a lot :wink_face:

post #930 of 933

The problem with the audio cutting out, lack of bass, right channel audio only, static issues are back. The 3.5mm audio port on the Pico slim is just poor quality. I've even brought this up to Justin, but got no reply. I've tried multiple cables, including 2 stock Westone cables and now the Linux Bax.

 

Does anyone know if the 3.5mm port can be removed and changed with a higher quality one? This is unacceptable for a $435 amp and makes listening to my music a pain and not a pleasure.
