C&C BH Portable Headphone Amp

My Review: see link below: https://ae8f1decb12a1a7b7992e5798da6d3caca73de45.googledrive.com/host/0BxYhWX_uhcC3bWJYS0V1T3Q1bWc/index.html

This is an amazing ultra portable amp. I paid 99$ for it and couldn't be happier. 
 
Sound
This amp has one of the best soundstage i've heard for this price , if not the best. The soundstage can easily improve with the switch ON . The detail is really good , and with the bass boost switch which also boosts treble a little bit , the detail and clarity is even more improved . There is another switch as well for higher impedance cans to give more juice but i rarely use it for my IEMs. 
 
Portability
Ultra portable , this amp is extremely small and comes with a case and all necessary accesories as well with a wall adapter to charge the batter within 6 hours instead of the usual 12 hours needed for amps.
 
Design
I would prefer the volume switch to be bigger so that i could easily adjust the volume , but i understand the logic behind this , since it is a very small amp and wanted to keep that size.
 
Price
This is a great amp for the money 

I'm really impressed by this tiny little amp. The C&C BH is truly a portable amp, hardly bigger than a tube of chapstick and boasting an insane battery that supposedly lasts 60+ hours. I've not yet charged mine since opening it a few days prior to this review and it's still going strong. The BH also has smart charging, so when it finally does run out of juice, you don't have to worry about over-charging it; it'll be good to go when it's full and won't damage itself. It can also be used during charging.
 
Build:
 
I have a few minor issues with the build. Sometimes, the jack is a little loose and needs a little re-adjustment to get the sound right. Only happens every once in a while and is easily fixed, but should be noted. The volume knob is almost too easy to turn and accidentally spike one's volume, especially IEM users. Again, not huge, but something to note. The knob is perfectly fine while the unit is in a pants pocket. Overall, it is very sturdy and solidly built.
 
Sound:
 
The BH is fun with the different switches and outputs available to choose. OUT1 has a more forward mid-range, making it lovely for vocals. OUT2 has less power than OUT1, but also has a wider soundstage and greater clarity. IEMs and lower impedance cans will be better on OUT2 than OUT1.
 
In addition to the different outs, the BH has a hi/low gain, low frequency switch, and soundfield switch. It's worth noting that the LF switch also boosts treble a little bit, but not to sibilant levels. 
 
I only have an AD900X to use with my BH, but the two pair quite nicely. The bass boost smooths out the lower end of the AD900X while maintaining a good level of clarity and detail on OUT2. 
 
For $100, I definitely recommend this amp. The sound quality is great and the battery life is out of this world.

This Isn't going to be a long review more so just some impression on how it sounds.
 
First thing that jumped out at me was the clarity over the FiiO E11, the BH was clear and more transparent making the E11 to sound much darker with less detail.
 
The bass boost or the LF switch gives the bass on my SM3 V2 more punch but what it really adds is depth, the sub-bass is much more prominent and I hear bass lines that I never heard before with the E11.
 
Soundstage gets wider as well as giving better depth to my SM3 and now the imaging and separation sound perfect, I can sit there listening imagining am at the club or festival (listen to mainly EDM) as the music is surrounding me.
 
There's really nothing bad about the amp that I can pick out and for $100 the C&C BH is a great bang for buck amp that really shouldn't disappoint anybody imo.
