C&C BH Portable Headphone Amp (80 Hours from a Single Charge!) [Buyer Review] - Page 188

post #2806 of 3287

thanks for the advice and the fast reply, i was also wondering what you thought of the ath m50 when paired with the bh i know it doesn't need amping but the amp in my phone is terrible, i would also appreciate it if you knew where i could get a usb micro-b lod? i've modded my android phone to support audio out over usb and was looking for one and googling has turned up nothing.

We've had members reporting good results with ATH-M50 through out the thread, the headphone has made our crazy synergy list on the first page however I cannot link you to any direct posts nor have I heard the pairing myself. Regarding the audio out via USB on your android, are you sure the signal is not digital out? because that would require a DAC which C&C BH does not have, I've not heard of an android putting out an analog signal via USB, unless I'm missing something.

yes its digital out i was thinking of possibly getting a portable dac at some point in the future, hence the need for the lod :smile:

Depending what the input on the DAC is, you will need something like this.

I don't like the price of that one particularly though. If you ever do need a cable I suggest contacting ClieOS and asking him if he knows of any sites,. because plugging DACs to smartphones is not my area...

I'm a complete novice to DIY projects. I want to be able to swap out the volume knob to something that is much harder to turn as I will be using IEMs. How difficult would this be and are there any guides on how to do this. Would I need a soldering iron?

 

Edit: If I want to remove the potentiometer it looks like I will need a soldering iron. Is there another easier way to make the dial harder to turn. I worry that if this amp is in my pocket and the dial slips I might either ruin my ears or worse ruin my CIEMs.

You could just try to place sort of an arch over and across the pot. So that it's harder to accidentally turn it. If you're not used to soldering it could be a solution. It's really loud this little amp. I'm barely listening at half past 6 and it's not really a quiet listen. If it doesn't screw up the sound on your CIEMs maybe you could try an attenuator as well.

I don't understand what an arch is. Do you have an image that shows one?

I think he means something like the volume knob protector on the Sony PHA-1 maybe using 1 or 2 U shaped bolts?

 

 

Or if you have any basic fabricating skills you could make something like this volume knob protector for the AK100  (available on Ebay Item number- 121139987120)

 

Processed By eBay with ImageMagick, R1.1.1.M2b

 

 

Or if you don't mind what it looks like... find a black bottle top or tiny plastic cup shaped item that internally is slightly bigger than the volume knob, drill a hole large enough for the pot stem through the centre of it. Cut a thin slice from the side of the bottle top to allow the side of the volume knob to extrude a little. Glue/attach it to BH and replace the volume knob on the pot stem.

Oh. Ithought I posted. I was thinking more in the line of Fiio E11. But tangential to that one. Or even put two in a cross.

I read a lot that people complain about the volume pot being loose but mine is actually fine - even a bit tighter than the E11. It's very hard to rotate it with one finger.

 

kova4a to the rescue again! My ws99's are quite easy to drive, and listening this morning through the BH (at the 6 o'clock point on the volume), I was hearing the imbalance quite a bit and thinking I'm losing my hearing in one ear. Found your post, switched it to low gain, and problem solved. I'll have to remember that. Strange about the imbalance at lower volumes.

Nothing strange about the imbalance at lower levels - all amps with volume pots have it - some are better and some are worse in that regard. It's usually around the first 10% of the volume. Amps with digital volume control don't have it - like fiio e7 or c5.

This is ClieOS observation about the E12. 


EMI and Hiss



EMI is quite noticeable on the E12. While far from blasting loud, it is annoying. Also, the amp not only picks up cellphone EMI, but has a tendency to pick up any nearby (within a feet or two) EMI source as well, such as 2.4GHz cordless phone. It probably not going to be great pairing if you are using cellphone as source.



 



Yes, I must admit that Fiio E12 is EMI prone, so far my work around for this issue is to use longer cable and separate my iPhone 5 as the source with the amp in another pocket in the jacket.

Hi, anyone here have the Fiio X3, Any thoughts in comparison to the BH/C3 combo . I'm looking to add a new dap to my chain and would appreciate some inputs here. As I have read a lot about the crazy synergy of the BH/C3 combo, how would the X3 compares as a standalone player. Any thoughts would be appreciated. Thanks in advance.

I would like to know this as well, alternatively comparison with DX50. If someone could share that would be great.

Thanks.
