Here's the box.
Now, in the contents you will get:
1x C&C BH Portable Amplifier
2x C&C Stretch Bands for pairing with your DAP's
1x 5V USB wall charger
1X Manual (in Chinese)
1x A nice storage pouch (I like this)
1x USB charge cable
3x Sets of foam ear tips S/M/L
1x Mini to Mini Interconnect.
The amplifier itself has decent build quality made of what appears aluminium, weighing in at 100 grams, the volume pot feels sturdy there's no play around the port, I actually like the volume pot because it's not overly big or in the way. Three switches on the back are firm flicking without any question or slipping around. The bands however are rather small and as you can see in the photo's they're rather tight just slid over the amp, they can however be stretched over an ipod classic with success! Myself will be using the bands as feet on the amp for now. Rubber bands are your friend.
The amp itself.
Good size, smaller foot print than E11 (about the size of a credit card) thinner as well, 13mm. As I said the build is solid, rated at 80 hours from a single charge, maximum output power: 300mW +300mW, this amp sounds as good as it looks, It's beyond what an E11 can meet having owned one in the past. Clean, powerful, smooth with good depth and detailing far beyond what I was expecting. Also, it has a wonderful black space behind the music the soundstage works very well and unlike other amps I've tried 100% of your clarity is kept from the source, there's no veil or loss in detail here, if anything this adds to the experience. It leans ever so slightly away from neutral towards cool.
This is where things become interesting because C&C BH has two outputs with output 2 being a P -> B circuit. I'm not exactly sure why we would use this but it does offer me two different flavours. I have used my 32ohm Hybrids through both outputs and they sound evenly clean, it's just when using output 2 I may need the high gain switch engaged. Green for power on / red for charge, pretty much the standard. The jacks however are not very stiff, they're not loose by any means but they are a touch light when plugging in your cables. This does feel like a design of the jack and not a fault.
On the back you have three switches, all of which work in a positive way, they're not just there for novelty fun. You have low/high gain, which does exactly what it says adjusts the gain, this would be used to power more hungry headphones of higher impedance. The second switch is strange but in a good way, it offers a bass boost of some sort but at the same time makes the mid and high range crystal clear, like it improves clarity, I absolutely love the amp with this switch on atm. The third is a sound field switch, which seems to expand the soundstage but it also changes some of the frequency response as well. And of course the USB charge input, the amp can be used whilst charging.
The manual, there are a few pages in Chinese I do not understand but working out the amp was a breeze and they're really not needed. What does interest me is a graph in the manual with three pages of what appears headphone models and a bunch of measurements they have done. I will post two pages to see if someone can work out what this means.
And some size comparisons
This is just a sneak peek into the C&C BH and is not the company's only amp. They have a model under for about $85 (BK) plus a few higher models so this company does not appear like a one off amp show, they seem to have some knowledge in the area, from what I've read are still highly recommended on Chinese audio forums even over iBasso models. (this is just what I have read). So far I can say this excels an E11 by quite a margin especially in SQ, the detailing levels especially micro details are really obvious, imaging is top notch and the depth in centre channel is rather deep. I'll have some updates over the next few weeks on my full thoughts, but so far with 80 hours rated from a charge, the sound quality and build this was an excellent purchase, one I can recommend for those wanting to step up from E11 for just a little more.

C&C BH (BH2) Differences.
The only difference between C&C BH and BH2 is BH2 has a user replaceable battery. When I say this I mean you can replace the battery by unscrewing the end plates and sliding the board out of BH2, whereas the original C&C BH had a hard wired (soldered battery). Far as we can tell from all user impressions the sound is exactly the same between the two units.
