[REVIEW] HiSound Audio’s Battleflag (Popo) / Crystal / PAA-1 Pro / Living

First, I’ll like to thank HiSound Audio (HSA) for the samples. A few years ago, HiSound Audio was introduced to Head-fi as an audiophile DAP maker and made a fairly big splash among the community.  Nowadays, they also have their own line of earphones. I’ll be reviewing one of their latest DAP, the RoCoo-P soon. But for now, let put our attention to some of their earphone models first, including two IEM models, Battleflag and Crystal, and two earbuds, the PAA-1 Pro and Living.

A few things to take note – Firstly, the official English name for Battleflag is ‘Popo’ (*no idea what that’s supposed to mean). The name ‘Battleflag’ is the direct translation of its Chinese name. Secondly, though I am reviewing Crystal, it is not the same Crystal currently on the market.  There have been several batches of Crystal being released in the past, and mine belongs to the previous batch. As far as I know, the same IEM is now being referred as Golden Crystal. So even though I am reviewing Crystal, you can equal it to the Golden Crystal as the current Crystal is a different sounding IEM of its own. Confusing? Yes, but we will leave that discussion to the build quality section.

The price on this models are: Battleflag – US$59; (Golden) Crystal – USD$199; PAA-1 Pro – US$49; Living - US$149.

[Impression] FiiO E17 'Alpen'

FiiO has done it again with another ultra-budget all-in-one AMP+DAC called the E17 – or as FiiO like to refer to its official name, the Alpen. Never did a portable headphone amp + DAC with these many features were made in the sub-$200 market. Then again, it is not the first time FiiO has broken the record in offering class-beating bang for the buck product.


All the basic accessories that comes with E17,which is pretty much the same as what you will receive on other FiiO amps. There are also an optical and coax adapter included (not show in picture)

CES2012: Aftermath

Like last year, CES this year gives little to no surprise as far as new IEM release are concerned. Your typical companies like Monster and SkullCandy are mostly showing off their old stuff; some new artist endorsed brands are (still) trying to make it big; some even just re-show their CES2011 line-up again (what is with that anyway?). The biggest news is actually Monster splitting up with the Beat by Dr.Dye brand, and I can't say it is a bad thing. Less boring than last year, even though the IEM market is still booming against the weak global economy.

Well, here is perhaps one of the most interesting IEM in the show - the AF78 by a new company called Audiofly. It is a balanced armature + dynamic dual drivers hybrid that will be sold at around $200. Not too bad a price actually.

MEElectronics is also showing off their latest line-up as well. The upcoming A161 is the most interesting as it closely resembles the Fischer Audio SBA-03 I have reviewed last year. If it is as good (or better), it will be something to look forward to. We shall see.

Digital Silence

There is nothing special about putting Active Noise Canceling (ANC) technology into IEM - Sony does it, Audio Technica does it, Panasonic does it, Pioneer does it (you get the idea)... and apparently,  Wolfson Electronics, the company best known for its DAC chips, is doing it as well. The sub-brand is called Digital Silence, and it already has a model in the market since mid 2011. The company now announced a new model called DS-421D with more advanced features, and as expected, it will pack a Wolfson chip inside to do all the ANC magic. The only question is, does it comes with an iron man certification?

Head to engadget for the whole list of features.
