  • The BA100 from HiSound Audio is a balanced armature inner ear monitor (IEM). It has a balanced frequency response, and small but very well constructed form factor.

    The fixed cable comes with microphone and cable button control, which is compatible with Apple products, and may be compatible with other smart phones.

    "Well balanced, but a bit bright sided IEM:s that need properly adjusted in place"
    Pros - Flat sound and decend built quality. Price. Microphone. Carrying case and cable holder.
    Cons - A bit harsh uppermid, with couple of nasty resonances. Hard to set in ears properly.
    Hello
     
    Just few words about my self: Im professional sound engineer, who enjoys pure and flat sound. Nothing hyped and no snake oil for me thank you.
     
    Just got them couple days ago, and i was very anxious to see, how they work for me. Lots of reviews i have read was very promising, but in this thread there have been so many dissapointed people, so...
    Package came from post and i plug those in to my iPhone4s and selected my soundcheck track no.1. and boy was i dissapointed. Weak bass, distorted sound and very peaky and unpleasant upper mids. Try to fiddle them out and in and try to adjust tips, and what not. Another, pro-audio soundsource did not make any difference.  No gicar. So i thought that these must be bad pair, and mailed to seller who runs local small busines and is specialised in in-ears, so he knows he´s product. He was baffled, but promised to check them out and to send me new pair.
    Then i listened my other familiar cans again, just to quadruple check, that it´s not me, and went back to BA100.s and suddenly whoa!!! Very clean and smooth soundstage. Good balance, exept slight overtightnes in upper mids. What happened? Take them off and on again and they sound thin again. Fiddling them in ears and boom, sound is back. So these things are VERY precise, how to place them in ears.
    Then i tried foamtips, that came along them and now i found that sweetspot much easier.
     
    So how is the overall sound?
    It´s quite flat overall. Subs are a tiiinybit shy, but definedly there. Bass is very clear, non hyped and precise and Lo mids are pure and nice. Upper mids are  a bit bright and there are resonance peaks at 3300 and its upper harmonics at 6600 Hz, and that bothers me quite a bit. I´m sure that many people wont even notice, and prefer this as clarity, and in a sense it is: you can find details exelently with these headphones, but do you need to find things that aren´t  naturally so visible? And it would be nice, if they could go a hint higher at the freq range.
     
    So overall: At pricepoint, they are very nice. Mick works fine as well. But you neet to adjust them very precise to get good sound off them and if you are like, me and use iems just on the go, when you want good sound, when you go jogging, biking or something like that, it´s a bit hustle. 
    So i still prefer my lost (sob) Sound Magic E10:s, wich are cheaper, not quite so flat, but exelent sounding and much more easier to use.
     
    PS: I found that when you place them so that cord points up and go from front behind you ear, they seems to settle down much easier.
     
    PPS. That distorsion that i mentioned when i first heard them, was in the record. Never before i have noticed it. So yes, they are very precise :wink:

    "Good for the price.."
    Pros - midrange, clarity, balanced sound
    Cons - treble extension, no chin slider
    Thanks to Jack and HSA for sending me the BA100 as a review unit for a hefty 50% off. It is a single balanced armature IEM with a retail price of $99. For a sub-$100 IEM, I would say that it definitely has a lot of potential with a few shortcomings.
     
    Design and Accessories : The first time I took them out of the packaging, I was quite pleased to see the metallic construction and the 45° jack. The wire is descent and has been rather tangle-free. The included tips are nice, I was using the foam tips that came with the BA100 for some time. Finally I switched to the MEElec double-flange tips which are very comfortable and also sound nice with the BA100. The included fish-thingy has been of no use and the absence of a chin slider is a little disappointing.
     
    Microphonics and Isolation : The isolation is descent and gets better by using a foam tip but not so much with the Meelec tips that I use. Microphonics is much lower than what I would have expected and wearing them over-ear eliminates it completely. I have to say that I think the soft wire used on these IEMs helps with the microphonics.
     
    Sound : Lets talk about the most important part, how do they sound? 
       Bass :  The BA100 has a tight and very well balanced low frequency response. The bass has nice quality and can redeem itself when needed. I am not a fan of bloated bass and am pleased with what HSA have achieved here.
       Mids : This is where the BA100 out-shines its competition IMO. I love the mids on them and specially how female vocals and guitars sound. I listen to a lot of Jazz and Blues and would recommend the BA100 to anyone listening to these genres if only for their wonderful midrange.
       Highs : The highs are a little weak on these babies, compared to their very well-textured lows and wonderful mids. Don't get me wrong, the treble is clearly present and sound good but without the extension as can be heard in more expensive dynamic or multi-driver IEMs. 
       Imaging and Soundstage : This is one part of the sound from an IEM that I am not very fond of. Considering that, the soundstage on the BA100 is quite wide and has good depth and height. The imaging is a little lacking but again few sub-$100 IEMs get it right.
     
    Overall, the build quality is excellent and the included accessories are good. I would say lose the fish and add a chin slider. I am very happy with how the BA100 sounds, given its price point. It is almost neutral with a slight preference towards being a little bright.  If I were asked to describe it in one word, my answer would be "clarity", especially in the midrange frequencies. I would recommend the BA100 to anyone who listens to Jazz, Country or Blues.

    Fit, Comfort and Isolation:
    The BA100 are one of the smallest in-ear phones I've seen, and like the Crystal model I previously owned, they're very easy to fit and impossible comfortable with the right tips. Unfortunately, to my surprise, I couldn't get a good fit with the included eartips, so tip-rolling was a must. Other single-flange tips, such as the Auvio and Audiofly tips, offered a more secure fit, but I ended settling with the Meelec double-flange tips as they offered better sound results.
    Isolation is above average, and again, potentially better with aftermarket tips.
     
     
     
    Sound:
    The BA100 are the first Balanced Armature based IEM from HisoundAudio and, according to a company insider, they've designed the BA driver themselves (and they're also one of the few companies that have the rights to design their own BA units).
     
    As expected, the BA100 feature the typical balanced armature driver characteristics, speed, accuracy and detail that beat most of their dynamic driver earphones rivals. They're also ahead of other BA ones, such as the PL50 and A151 that use the well known Knowles Siren driver.
     
    The overall sound is neutral with an added touch of brightness, well balanced from lows to highs. Within the HSA line they offer a totally different presentation compared to the much colored, darker or V-shaped sounding models. What that they do share with previous models is the extra volume to shine and also need some more time to get used to their sound to really start to appreciate it.
     
    The low end is very tight, fast and detailed. As a full range single BA driver, sub-bass is very limited in extension, depth and rumble but it's more rounded than something like the SoundMagic PL50. When it comes to mid-bass, they're quite surprising. While they remain on the neutral side, there's a small extra 'hump' or kick in the mid and upper bass that adds some fun to whole presentation, making up for the sub-bass lack.
     
    The midrange is slightly forwarded, but on the whole has fairly neutral tone. Like a true BA it's very effortless and detailed. While other similar priced single BA may focus more in bringing sweeter and thicker mids, the BA100 offer more transparency and clarity. Vocals, both male and female ones, are given higher priority than the rest of the mids. They lack the texture and sweetness that more mid-centered IEMs (both dynamic and balanced armature) can offer, but manage to be quite enjoyable on their own.
     
    As for the highs, they have more than enough quantity and could even fall into the 'bright' category. They are very crispy and energetic. When it comes to quality they are somehow splashy at the lower treble region and lack the definition and control of higher-end and pricier BA-based earphones. There's no hint of grain, and while not exactly smooth or flat they are never peaky even with less forgiving tracks.
     
    Surprisingly, soundstage has good width and height. Wider than the RE-400 for example, but not as resolving, and don't have that 3D feeling either. Air and separation is pretty good for the asking price, and they can handle complexity with not much effort.
     
    While I can't really say that the BA100 is able to match pricier single or multi-BA earphones, they do compete quite well in their sub $100 price bracket and are a good option for those who want to know what a true balanced armature earphone is capable of. There is still some room for improvement, though, but I think HisoundAudio has made a nice first step into the BA market.
