    Pros - •super even, harmonious and smooth frequency response
    •higher evenness and tonal realism compared to the BS1 Experience Version make the BS1 Official already the more mature and superior model
    •truly awesome cable
    •plenty of premium accessories
    •great bass control
    Cons - •slight lower midrange bleed
    •a little more resolution in the highs at the price point would be nice
    •the awesome cable is, unavoidably, heavy, which is something potentially interested people should be aware of
    Es gibt noch immer Audio-Enthusiasten, die die klassischen Earbuds In-Ears und kompakten Bügelkopfhörern vorziehen. Anders als das „nicht-audiophile Fußvolk“ nutzt der enthusiastische Earbud-Hörer aber keine Modelle vom 10€-Grabbeltisch des Elektro-Discounters, sondern ist bereit, für einen guten Ohrhörer durchaus auch mehr Geld in die Hand zu nehmen – manchmal sogar wesentlich mehr Geld, denn auch bei Earbuds gibt es Modelle, die preislich jenseits der 200€-Grenze liegen.

    Ganz so teuer sind die Penon BS1 Official Earbuds nicht, liegen mit einem Preis von 99$ allerdings auch definitiv und unverkennbar im Enthusiasten-Bereich und sind für den uninformierten Casual-Listener damit wohl eher uninteressant, wobei auch der Durchschnittshörer nicht abgeneigt zu sein scheint, einen dreistelligen Betrag für Earbuds (nicht In-Ears!) auszugeben, wenn diese kabellos sind und mit smarten Health-Monitoring Features ausgestattet sind.

    Anyway, nachdem die Penon BS1 Experience Version Earbuds im Review in ihrem Preisbereich überzeugen konnten, kläre ich in dieser nun folgenden englischsprachigen Rezension unter anderem, in wieweit sich die teureren BS1 Official Earbuds von diesen unterscheiden. Auch müssen die teureren Earbuds gegen andere, sehr starke Earbud-Gegner im Direktvergleich antreten.
    So here we go:


    In 2017, I reviewed the Penon Audio BS1 Experience Version earbuds, and they definitely convinced me with good tonal balance as well as harmony and a more “meaty” tonal approach along with good technical performance for earbud levels and their price point. They even won a golden Lounge Award (2017) in the category of earbuds.
    That the BS1 Experience Version earbuds would be just a teaser for, and more affordable option to the actual BS1 was however also rather publically known.


    And so it came – besides their new “Penon Official” website where Penon Audio sell some of their Penon-branded products besides their regular web shop where they resell audio products from a wide range of manufacturers and categories, they also released the BS1 Official earbuds that are, no doubt, definitely geared towards earbud enthusiasts with their luxurious, braided copper & silver cable as well as a price tag of $99.

    How do the BS1 Official earbuds sound like? How do they perform? And in what areas do they differ from the regular BS1 Experience Version? This is what I will find out in this very review.

    Technical Specifications:
    Price: $99.00
    Type: Earbuds
    Driver: dynamic, 15 mm
    Impedance: 32 Ohms
    Sensitivity: 120 dB
    Frequency Range: 14 Hz – 28 kHz
    Cable: 1.2 m, 8 conductor 19-core silver-plated & copper cable

    Delivery Content:

    The BS1 Official earbuds arrive with a lot of accessories that are pictured below:


    The earbuds, one wooden storage box, one soft storage pouch, one large shirt clip, a Penon-branded Velcro cable tie, and no less than 13 pairs of different foam covers.

    Looks, Feels, Build Quality:

    Got wood?
    The BS1 Official earbuds come with a wooden storage case that is made of dark brown walnut wood and looks very beautiful. Those who don’t want to use it can use the other included storage solution, a cream-coloured and very soft pouch (that is however a tad too small for the earbuds including their cable).


    The earbuds’ cable is simply gorgeous, very premium and flat-out bonkers! It is a hybrid, beautifully braided 8-conductor silver & copper cable with fairly high flexibility (although not as high as twisted or braided three- or four-conductor cables).
    The large y-splitter and 3.5 mm plug have got beautiful, built-in carbon fibre elements. And the chin-slider (that is by the way also made of metal) is large, too.
    Yeah, that cable’s appearance and quality is simply gorgeous.


    I also really like that the included Penon Velcro cable tie is green, since I love this colour.


    About the BS1 Experience Version, I complained that the side-markers on the metal shells were way too simple (just a small white dot on one side). Thanks to the red and blue side indicators on the BS1 Official earbuds’ cable, I cannot report the same and am happy that distinguishing the correct side is super easy.
    The design of the buds themselves is mostly similar, however unlike the BS1 Experience Version that had acoustic screens made of plastic in front of the driver, the BS1 Official earbuds’ are made of metal (let’s just hope that no rust will build up over time).
    The pure buds’ shell shape and design is still a tad boring, at least to my perception, but not anywhere as much as the BS1 Experience Versions’, since the Official earbuds have etched Penon logos on the outside that give them a less stealthy look, which is an outcome I personally prefer, just like the coloured side-markers.


    Comfort, Isolation:

    The comfort will of course highly depend on your individual ear anatomy.
    For my large ears, comfort is quite good and the earbuds also seal rather well (within their limits of course).


    Due to the good cable, microphonics are reduced to a minimum and can be even lowered when inserting the earbuds regularly but guiding the cables around the ears. However, since the cable is rather heavy as well and also undeniably on the thicker side, the earbuds might be pulled out unintentionally if you don’t support them using the included shirt clip or guide the cables around the ears.

    Exterior noise isolation is, which is not that much surprising given these are earbuds, pretty much not present at all.


    My main sources for listening were the Cowon Plenue 2, my Apple iPod Nano 7G, the Hidizs AP200 as well as the iBasso DX200 (AMP1 module) although that’s mostly irrelevant for the BS1 as long as the source outputs a flat frequency response under a low impedance load and doesn’t perform too bad in general.


    As usual with earbuds, the sound one will hear is strongly dependant on one’s personal ear anatomy and especially how well the earbuds seal and how tight they fit.

    I didn’t use any foam covers for listening.


    Foam covers versus no foam covers – that is the question… that you will have to answer for yourself. Speaking for myself, I generally prefer to use earbuds without any foam covers, and that’s also how I evaluated the BS1 Official.

    The BS1 Official earbuds head into a smooth, somewhat warm direction that can be described as quite inoffensive and even in the treble. So it’s a natural, harmonious frequency response that the BS1 Official earbuds convey.

    Starting with the bass, the BS1 Official have quite surprising sub-bass extension for earbud levels and manage to still reproduce a bit of that rumble around 40 Hz.
    Bass elevation starts around 800 Hz and reaches its climax around 150 Hz. It can be kept upright until about 60 Hz and rolls off below that.
    As a result of the warmth-driven tuning, lows and deep male voices gain some warmth and fullness, however bloating and unnaturalness are fortunately avoided and the midrange is not overshadowed by much, although I wouldn’t mind a bit less fundamental range bleed into the lower midrange for this price. The bass has got a nice punch and impact to it without being really overdone or omnipresent (lows are elevated by ca. 7 dB compared to an in-ear that is diffuse-field flat in the lows, such as the Etymotic ER4SR/S).

    Voices are on the smoother, warmer side but sound mostly natural. Still, the lower midrange can be a touch too full at times.

    The treble in general takes a slight step back and is overall minimally more on the inoffensive and smoother side. What’s quite remarkable about it is that it is mostly quite even, without any sudden dips or peaks.
    Extension past 10 kHz is really good.


    Bass is a bit more on the softer, looser side, but has got good control and texture – in this regard, the BS1 Official are a bit better than the BS1 Experience Version, even though sounding a bit softer.

    Midrange resolution, definition and speech intelligibility are on a good level as well, however this area is ultimately slightly behind the Shozy Cygnus.

    Treble details are certainly there and also rather precise, although one should definitely not expect better in-ear performance – but that’s what most earbud lovers are aware of anyway, and other good earbuds aren’t significantly better in this area either.

    Coherency between the lows, mids and highs is good and no area seems to really fall behind the others.


    What you might notice is that the BS1 Official don’t have the most prominent forward projection. While there is some spatial depth, layering and real depth are somewhat less present. Instead, the BS1 Official concentrate more on the lateral presentation, presenting a rather wide but not super wide soundstage that will never appear congested and that slightly leaves the base between my ears wherefore it is not the most immersive soundstage for earbud standards, however not the smallest either and presents a good median (maybe even a bit more than just that).

    Separation and placement of instruments don’t reach the same level as similarly priced in-ears or the Shozy Cygnus and appear a little smudgy in comparison, but judged by earbud-standards, the BS1 Officials’ spatial presentation is still solid.



    In Comparison with other Earbuds:

    Shozy Cygnus (no foam covers):

    If you already thought that the Cygnus had a very gorgeous and premium cable, then you probably haven’t seen the BS1 Official yet – their cable is a lot more luxurious in comparison to the Cygnus’ already awesome cable. On the other hand, the Cygnus’ cable has got the higher flexibility since it isn’t as thick as the Penons’, and I find that the Cygnus’ buds appear more premium and beautiful with their silky smooth white finish and curved design.

    The BS1 extend deeper into the sub-bass. Bass in general is ever so slightly more forward on the Penon as well, but the Penon earbuds are overall also audibly warmer than the Cygnus. However, while the BS1s’ fullness is pleasant, their fundamental range bleeds a little too much into the midrange.
    Mids are, as a result, more neutral on the Cygnus, with a more correct timbre.
    The Cygnus are closer to neutral in the highs and even slightly on the brighter side around 10 kHz, and also minimally around 6 kHz wherefore treble evenness is where the BS1 Official are a bit ahead.
    So the BS1 are smoother and a bit warmer as well as fuller sounding whereas the Cygnus have more of a tastefully balanced v-shape with more neutral mids.

    Bass is tighter, faster and better controlled on the Shozy.
    Midrange resolution and speech intelligibility are slightly higher on the Cygnus as well.
    Treble separation is also a bit sharper and cleaner on the Cygnus.

    The Cygnus sound a bit more open and separate single notes and instruments more precisely in comparison.

    Penon BS1 Experience Version (no foam covers):

    The BS1 Official have got a far more premium cable with the slightly higher flexibility and come with far more accessories that definitely match the price and are high-class as well.

    The BS1 Official extend somewhat deeper into the sub-bass.
    Midbass is slightly more present on the BS1 Experience Version while the BS1 Official have got a bit more warmth and fullness in the fundamental range and low mids.
    The BS1 Experience Version have got a bit more upper midrange presence and sound therefore slightly more metallic in comparison.
    The BS1 Official are more even in the highs in comparison and also extend further.

    The bass is where we have the biggest difference between the two earbuds – control and texture are higher on the BS1 Official while the BS1 Experience Version shave got a bit more tightness and speed.
    Due to the higher evenness in the highs, the BS1 Official sound more focused, even and natural in the mids and highs in direct comparison while actual detail retrieval and speech intelligibility are quite similar.

    Soundstage is, to my ears, quite similar in terms of size, openness and spatial precision/imaging between both earbuds.


    The Penon BS1 Official earbuds are a product dedicated to earbud lovers who want luxury. They don’t only come with a plethora of accessories and a really premium wooden storage case, but also with a truly impressive, braided 8-contuctor with silver and copper wires and carbon fibre elements incorporated into the 3.5 mm plug and y-splitter.


    Sound-wise, they present a quite smooth, even tonality that heads into the somewhat warmer, fuller direction, but also comes with a bit of lower midrange bleed that could be lowered a bit. So all in all, they appear like an overall somewhat more refined, more even sounding version of the BS1 Experience Version earbuds with somewhat more warmth and fullness, along with an impressively luxurious cable and really nice amount of luxurious accessories.
    While they are good earbuds and worth their money as generally quite well-tuned, luxurious earbuds, a slightly higher resolution along with slightly improved separation and a lesser lower midrange bleed are however things that could have been improved somewhat.
