Penon BS1 Official Version

This is a personal unit I bought from a fellow hobbyist. It has been with him for a few months now, totaling to nearly a year being used. The product has been burned in, and has shown signs of oxidation due to frequent usage. Nevertheless, the oxidation of the cables is the user’s fault, not Penon’s. In storing earbuds with cables that are prone to oxidation, use silica gels or other desiccants to get rid of moisture as to avoid oxidation.

Currently, Penon sells the BS1 Official in 3.5mm standard termination and 2.5mm balanced termination. You can purchase them at the Penon official website for 109$ at the least (https://penon-official.com/product/bs1-official-version/) or via Shopee if you’re from Philippines (https://shopee.ph/Techshop28-Penon-BS1-Final-Edition-Earbuds-detacheable-i.16685303.1167000149)

Disclaimer:

I am not affiliated with PENON Audio in any manner. I do not receive any cash incentives, rewards, or anything from them. This review is my non-biased comprehension and appreciation of the said earbud.

Personal Preferences:

• Packaging is important. First impressions can last a long time.
• I do not have a specific genre that I listen to. The songs I listen to differ greatly from billboard tops to old classics, pop, rock, edm, acoustics, alternatives, metal, and all of its sub-genres. I incline listening to metal music, specifically to power metal, death metal, and the likes.
• I enjoy variety of sound signatures, ranging from bright analytical, balanced with only a slight dip in mids, neutral warm, and neutral bright. I generally lean to neutral-bright sound signature, with a certain degree of analytical sound. I dislike over powering bass, as it diminishes my experience of enjoying listening to music.
• I prefer iems over earbuds, earbuds over headphones.
• I review the products in both quiet, such as in my house or when I’m lying in bed, and loud environments, such as my daily commute.
• When listening to earbuds, I cycle around full, donuts, and just plain naked. I generally incline to using donut foams.
• When listening to iems, I prefer using my Symbio Wide bores as they are the most comfortable of my collection, and they bring a good amount of detail and extension in both lows and highs.

• Cable: 8 Core 19 Strands Copper & Silver-Plated Mixed Cable
• Plug: 2.5mm Straight Copper Gold-Plated Plug
• Cable Length: 1.2m

Packaging:

As I have said before, packaging should always be taken seriously, as first impressions always matter. In this price range, one cannot expect a product to have ridiculously bad packaging. Thankfully, Penon delivered their earbuds in a small, discrete way that still gives a premium unboxing experience.

The Penon BS1 Official comes in a small, red and blue themed, high-quality cardboard box. The etched text up front reads the company name in gold, “PENON”, with their logo beside it. The right side of the box displays the model of the earbud purchased, which indicates whether the BS1 the buyer purchased is terminated into 3.5mm TRS of balanced 2.5mm TRRS. Behind the box is the product description in English, together with Penon’s home and email address at the bottom.

Lifting the lid of the packaging, the buyer is greeted with a small, stubby, cylindrical wooden container. The company’s logo and name is also etched in the container’s cover. The wooden case houses the beautiful BS1 in all its glory.

Besides having the wooden container, there is a small, velvety, carrying pouch which houses the various donut and full foams, color coded in black, red, and blue. There is also a vintage-style metal shirt clip included.

In total, the buyer receives:

• BS1 Official earbud
• Wood case
• 1 pair of Hiegi foam donut eartips
• 1 pair of Hiegi foam solid eatrips
• 4 pairs of donut foam eatips
• 4 pairs of solid foam eartips
• 1 pair of transparent earhook
• Pouch
• Clip

All in all, Penon delivered a simple, yet outstanding unboxing experience. The accessories that come with the package are adequate enough for the price range.

Build:

The BS1 Official does not fall short in build quality. The buds scream premium just by feeling and looking at it. The metal housing of the shell and stem, the thick, braided hybrid cable, the carbon stripped y-split with the branding “BS1”, hell, even the circular chin slider is premium. These buds do not just please our hearing, they please our sight and touch, too.

The shell of the drivers looks like an alien spaceship you see in conspiracy videos. At first glance, I thought the buds would seem uncomfortable as they do look intimidatingly large. However, they do fit very comfortably. At the back of the shell is where the company name is etched, “PENON”, in a manner that it wouldn’t be erased through handling as to boast confidence to the owner. There are three noticeable bass vents below the metal grilles in each driver. The stem is relatively cylindrical and color-coded, with blue being the left and red on the right.

The copper and silver-plated mixed cable is a sight to behold, though my unit has its fair share of oxidation. The braid is elegant, with no mismatch in constructing the cable. The braid is homogenous, reliable, in a sense that there is no single strand that is in conflict with the braiding. The copper and silver-plated cable is wrapped in soft TPU that doesn’t degrade over time. While other TPU coverings become sticky and icky, as if melting away, the ones in BS1 remains fresh, though the cable can be springy sometimes, retaining the bends from how it is kept away.

Penon did not hold any bars in constructing the BS1, even in the y-split and the chin-slider, and the termination. The circular chin slider is a great add on, though I do not really use it. The y-split has the branding “Bs1” on top, a carbon strip at the middle, and is hex screwed to increase longevity. It does not have a strain relief, though. The plug also has a carbon strip down the middle. The company name, together with its logo, is also printed in the gold plated copper 2.5mm plug. The plug feels durable with a lengthy strain relief to reduce the chances of wear and tear.

Great build quality means longer longevity. After all, for a 100$ earbud to last, it has to have premium build to withstand everyday usage. Again, Penon did an outstanding job in sourcing the materials used to creating the BS1 Official.

Fit and Comfort:

For me, the yuin shell offers the most comfort out of all the shell types in earbuds. Though the BS1 does not sport their buds in a yuin shell, they manage to be comfortable still, though not as comfortable as yuin. They have a shallow fit in the cavity between the tragus and anti-tragus, but they still manage to stay in my ear despite violent head shaking. The stem barely sticks to the ear notch due to the large housing. The cable is not on the heavy side, though it does have a little bit of weight to it, probably due to the chin slider and y-split, but it does not hinder the listening experience.

The BS1 demands to be felt. The fit and comfort of these earbuds are great, not in a sense that they are the most comfortable out there, but for an earbud to shine, it has to stay in the user’s ear for his or her long listening sessions without delivering fatigue. The BS1 has no compromises in comfort when using premium materials. The design of the shell is unconventional, yet still comfortable.

Sound:

In sound observation, I found that donut foams delivered the most detail while still managing to have a punchy bass and non-fatiguing signature.

The BS1’s sound signature is phenomenal. It is balanced across the spectrum, with a slight elevation in lower vocals. The vocals sound closer than the instruments. The sound stage is wide. Bass performance is exceptional. There is no sacrifice in details. Overall, the BS1 Official has a mix of both analytical and relaxed tuning, resulting in an engaging sound with smooth presentation.

Bass –

The BS1 handles the lower frequencies very well. Bass extends deep with adequate rumble and fast decay. The response of both the mid bass and upper bass is fast and controlled, not meddling with the affairs in mids or highs. There is a decent amount of sub bass. The earbud adjusts accordingly to whatever song genre the user is playing. If the song requires a good amount of bass, it does not fail to deliver. If the song requires minimal and controlled bass, the BS1 does not come as too powerful. The sound delivery of the lower frequencies adds smoothness while still maintaining clear and crisp details

Mids –

The amount of vocal detail is intense. The vocals are not too meaty, nor dry. They are presented in a smooth manner, while demanding itself to be felt by the listener, whether it be sweet serenades or loud screamos. They can be quiet shouty at some busy songs, but nevertheless, the vocals are still presented in a forgiving manner.

Instruments in the mids section are distinguished. Layering is very prominent against each other, and against the vocals. The mids can sound sexy, melancholic, and relaxing, whatever genre the user is playing. Overall, the BS1 delivers a natural and smooth approach in the mids section.

Highs –

Analytical earbuds can be an earsore for long listening sessions. While BS1 does deliver great sparkle and crisp details in the highs, it does not come off as fatiguing. The natural presentation of the highs has great extension and a degree of space to it. The instruments in this section do not congest themselves; rather, the separation is excellent. What more can one say? For a 100$ price tag, these earbuds do not fail in details and separation.

Soundstage –

The BS1 has an airy feel yet still manages to be full-sounding. There is naturally wide soundstage to it, which, when coupled to how the instruments are well separated, results in a wonderful, wide and smooth presentation. Imaging is excellent, as instruments can placed very accurately around the listener

Conclusion:

ThePenon BS1 Official are by no means an excellent earbud. They perform very wellin all genres I throw at them. Though they can be quiet shouty at some time,the BS1 still manages to sound smooth and forgiving. It is the perfect mix fromboth analytical and relaxed listening. Everything is premium, from buildquality to sound. They do truly bring a remarkable listening experience.

Introduction: Penon Audio is a Hong Kong company that has not only sold products on their own site at competitive prices for quite some time but they have also started to produce the their own line of products. They started with the BS1 Experience Earbud and followed up with several custom cables, and now they've recently updated their BS1 Experience earbud to the BS1 Official which is a step up in build, performance and price to the Experience.

There are currently two versions for the Penon BS1 Official, a standard with 3.5mm jack ($99 USD) and the one I have now which is the 2.5mm jack ($109 USD) or balanced plug, which I'll be reviewing. Please note I'll sometimes call the BS1 Official as just BS1 throughout the review. You can purchase the BS1 Official at the Penon website HERE or locally if your retailer has them in stock. I would like to thank Penon Audio for providing me with a review sample in exchange for my honest and unbiased review.



Specifications:
Sensitivity: 120dB
Impedance: 32Ω
Driver: 15mm Dynamic Driver
Frequency Response: 14Hz - 28kHz
Cable: 8 Core 19 Strands Copper & Silver-Plated Mixed Cable
Plug: 2.5mm Straight Copper Gold-Plated Plug
Cable Length: 1.2m

32Ω is becoming a popular impedance in ear gear these days, likely from a viewpoint of being able to provide a better audio experience that is still relatively easy to drive. At a sensitivity of 120db, the BS1 Official is able to provide a good (and relatively loud) listening experience even on mobile phones (like my low output XZ Premium) and portable gaming gear.



Unboxing: The BS1 Official came in a simple and compact box with the Penon branding in the front and the model type on the side. Behind the box is the specifications and description of the earbud, and inside you'll find the beautiful circular wooden case that holds the BS1 Official.



Under the case is the soft carrying case that holds 2 packs of various foam covers for the earbuds, a metal shirt clip and a Penon branded cable wrap (in green!) Inside the wooden case lies the Penon BS1 Official.



The BS1 Official cable is one of those rare nicely braided 8 core types that are flexible.

Cable: The first upgrade given to the Official vs the Experience is the 8 core hybrid cable, made of 19 strands of copper and silver plated (copper) wire. The braids on the cable are nice and uniform, no wire is out of sync with the whole. The wires are coated in transparent TPU and they dont feel sticky or overly smooth. There's enough looseness so that the overall feeling of the cable is relatively soft and flexible though there is a certain amount of sponge like spring when they're first taken out of the case. Overall the cable looks good and pricey, feels supple and strong too.





Metal alloy, carbon fiber sheath design, gold plated copper plug.

Build/Design: The plug is a Penon branded screw on metal alloy jacket with a black carbon fiber strip design. It terminates in a gold plated copper 2.5mm plug that's smooth, looks good and feels sturdy. There is a rigid transparent strain relief at the opposite end of the plug.



Black carbon fiber splitter, alloy slider

The splitter is made of an alloy metal with "Bs1" branded on the upper metal part and the middle of the splitter is wrapped in a strip of black carbon fiber. The slider is made of the same alloy material and has dampeners inside so it does not slide around loosely, it has enough grip to keep it's position and still slide along the wire without much effort.



Made of metal, but it rocks!



Air holes, wires, that UFO shell design

The other half of the upgrade from the BS1 Experience is the metal shell used on the Official, it has 3 small bass port holes near the cable stem side, a metal mesh driver cover and metal cable stems. Everything here feels solid, smooth and inspires confidence in it's build. The 15mm driver is a bit easier for me to fit in my ears with the donut foams and feels most comfortable (and stable) when the wire is looped over my ear like an IEM with the bud hanging in my ear. In this config I can move around while maintaining a good enough seal to enjoy listening and still let some loud ambient sounds enter my ear. The bud is low profile enough to be comfortable in a sleeping position and light enough to feel unobtrusive with normal use.



Sound Stuff: When I first tried the BS1, I felt like it was a good balanced earbud from the get go, it had good soundstage and clarity and made me feel good listening to music. Later on though, I tried using the donut foams more than the stock full cover foams which resulted in better performance and fit, but knowing that it's a dynamic driver, I let them play music for over 150 hours so they can stretch out a bit, then tried listening and comparing them to my other earbud, the HiFi Boy Dream after. Being a balanced plug, I was able to use it on my WM1a (with a 4.4mm adapter) and my R6 directly, and with another adapter for 3.5mm, I was also able to test it on my Zishan Z1, phone and Nintendo Switch for driveability tests.

Bass: The BS1 has a good amount of sub-bass, and songs with slam hits well enough to be felt. Bass extension is moderately deep and it keeps drum driven songs like Way Down Deep sound lovely with a bass decay that's a little fast and yet gives a good rumble. The BS1 is able to resolve and separate dissonant sounds with good control and speed, songs like The Day the World Went Away and Lithium sound natural and fun. Overall, the BS1's bass warmth adds smoothness and body with the music you play and presents the bass frequency with a good amount of accuracy and clarity that sounds good and engaging.



Mids: The BS1 commands a good amount of ability here with the clarity and detail it presents to the listener. On female vocals, there is a bit of forwardness with the upper mid area that gives them a slight advantage in presence and intimacy vs male vocals as if Norah Jones is serenading you by your ear. This does not mean male vocals or the lower mids are ignored, neutrally placed, there is a thickness to the body that prevents them from sounding dry or hollow. Separation is good here and lets you listen to instruments, voices and sounds without straining to hear one over the other. The overall warmth and thickness lends to a smooth experience but it's not too thick that it sounds unnatural.

Highs: There is a natural extension with the treble of the BS1 that has good clarity, some sparkle and a great amount of air. The guitars and bagpipes on It's a Long Way to the Top scream into the BS1 and it delivers them in a full bodied and energetic manner with no sibilance or harshness, while orchestral music and violins from Vanessa Mae in particular, practically sing with emotion on the BS1. Separation is good here too as music sounds uncompressed and smooth aided by the air and warmth that the BS1 offers.

Soundstage: Has very good width and depth that extends naturally around the listener, this lends to an airy atmosphere that makes listening to classical, orchestral, stringed instruments and acoustic performances sound realistic and accurately placed.



Comparisions:
Penon BS1 Official vs HiFi Boy Dream
(Both are using donut foams and volume matched to 90db)
Both the BS1 Official and Deam have relatively balanced tonalities, but the BS1 has more sub-bass quantity and extension than the Dream which has a faster sub-bass decay vs the smoother texture of the BS1. The mid bass of the BS1 is fuller and has a bigger slam then the Dream. Both do not bleed into the mids.

Lower and higher mids have more body on the BS1 and male vocals sound better because of it than on the Dream. Female vocals are more forward and intimate with the Dream but the thicker body of the BS1 lends a more sweeter taste, and though there is clarity and transparency in both, the Dream edges the BS1 in both by a little bit.

Though both are able to control sibilance and harshness greatly, treble highs are presented with more body and smoothness with the BS1 than on the Dream. On the other hand, the Dream is more crisp and sparkly in that regard than the BS1.

In stage, the BS1 and Dream has similar and natural expansion but the Dream has less vertical depth than the BS1. Detail retrieval, layering and separation is again similar on both though the BS1 has a bit more ability to retrieve detail.



Conclusion: From the classy wood case, packaged accessories, it's solid and smooth built shell, to the braided 8 ore balanced cable, the BS1 Official is a great balanced sounding earbud for all kinds of music (Though I confess to suddenly listening more to classical and orchestral music thanks to this). It has an overall smooth and full bodied sound that still carries good and palpable bass, vocal beauty, clarity, very good levels of detail retrieval and a resounding treble. The wide soundstage and air are icings on this delicious cake.

Note on cable: an 8 core cable on a bare earbud can be hard to keep in your ear and can be a bit too heavy for some. The solution I had for my ear structure, is to place the earbud stem 45 degrees up place the cable wire on my ear and hang them down from there like wearing In-Ear Monitors. Other options you may consider is ear hooks.

Pros: Good packaged accessories, great build quality, amazing cable, choice of 2.5mm and 3.5mm, relatively easy to drive

Cons: Cable a little bit springy

Nitpicks: I really wish there were ear hooks included in the package.



Sound testing was done using a Sony WM1a (Primarily), a Hiby R6 and Zishan Z1(for comparison) and a phone (for checking driveability) volume matched to 90.X db of max volume for safe hearing below 8 hours of use and calibrated using a 1kh tone on a dedicated DB Meter, all sources patched through a switcher. More information will be available on the About Me page (once I find the time to write it up.)

BS1 Official Version Review: Extra-Aural Luxury
Penon Audio is a distributor for ChiFi products. They operate, unlike many audiophile shops based in China, on their own platform, rather than inside a larger market such as Aliexpress. They’ve established themselves as a trustworthy business, and one that offers some pretty competitive prices at that. Until recently, they’d only worked on the distribution side of things. But now Penon Audio has gotten into developing their own products. The BS1 is their brainchild and, after several iterations, it has reached its final form. But what even is a luxury earbud?

You can find the BS1 Official Version for sale here, for $100-$110. It is available with a 3.5mm TRS cable termination or a 2.5mm balanced cable termination.

About My Preferences: Heads up, I’m a person! As such, these words are my opinion, and they are tinged by my personal preferences. While I try to mitigate this as much as possible during my review process, I’d be lying if I said my biases are completely erased. So for you, my readers, keep this in mind:

• My ideal sound signature would be an extended sub-bass with a leveled, but textured, mid-bass.
• I have a mild treble sensitivity.

Source: The BS1 was powered like so:

HTC U11 -> Zorloo ZuperDAC-S -> earphones

or

Hidizs AP100 3.5mm out -> FiiO A5 3.5mm out -> earphones

or

HiFiMAN SuperMini -> earphones

or

PC optical out -> HiFiMe SPDIF 9018 Sabre DAC 3.5mm out -> earphones

All music was served as MP3 @320Kbps or as FLAC.

Tech Specs

• Driver: 15mm dynamic driver
• Impedance: 32ohm
• Frequency response: 14Hz — 28 kHz
• Sensitivity: 120dB
• Cable: 8 strand, 19-core, copper & silver-plated cable
• Cable length: 1.2m

Sound Signature
Sonic Overview:

The BS1 Official Version has a very natural-sounding sound signature. It features a hearty mid-bass, a linear midrange with a mild warmth, and an energetic, well-extended, treble. The BS1 is incredibly cohesive despite not being able to seal on the ear like an IEM can.

Treble: Songs used: In One Ear, Midnight City, Outlands, Satisfy, Little One

The BS1 hits a lot of the right notes with its treble presentation. Articulate and natural-sounding, it provides the listener with a life-like presentation of whatever they’re listening to. Detail retrieval is pretty good, by earbud standards, and above average for this price point.

The BS1 managed to pick up the amp-buzz in the intro of In One Ear with relative ease. It continued to grab background details throughout the rest of the song. High-hat and cymbal tonality and presentation is really good too.

The BS1’s treble extends very far and remains even and tempered all the way up. Such extension and control gives the BS1 an airy presentation that aids its instrumental separation.

Midrange: Songs used: Flagpole Sitta, Jacked Up, I Am The Highway, Dreams, Too Close, Little Black Submarines

The BS1’s mids are surprisingly rich and well-weighted. Normally earbuds have a hard time maintaining their warmth without creating a messy presentation, but the BS1 has no such flaw. Its 15mm driver creates just enough emphasis in the lower-midrange to give electric guitars satisfying chugs and male vocals a natural timbre.

The upper-midrange is equally capable, nailing the articulation of drums and vocal intelligibility. The midrange's detail retrieval is also quite good, in spite of its recession in the sound signature.

The BS1 does not prefer male vocals over female vocals (or vice versa) to any noticeable degree. They are both well-weighted and intelligible. The BS1 captures a lot of detail in that frequency range. It often times reveals small attenuation or inflections in the vocals.

Bass: Songs used: Moth, Gold Dust, In For The Kill (Skream Remix), War Pigs (Celldweller Remix)

The BS1 has a decent mid-bass presence. Given its form-factor, having any punch at all is quite the achievement. So while the BS1 doesn’t have a lot of quantity of bass, it more than makes up for that in quality. The mid-bass is precise and well-controlled. Bass drops are dynamic and engaging, and instrumentation that lives in the lower-register maintains a lot of texture, even if it doesn’t quite rumble.

Packaging / Unboxing
Build
Construction Quality

The BS1’s shell is made entirely from a light metal. It is machined very well and is free from manufacturing errors or defects. The shell doesn’t have any external stress relief for the cable as the BS1, as I’m told, takes care of that inside the shell to improve aesthetics. The inner face of the BS1 is also metal. The “speaker grill” is finely perforated at even intervals, each hole cut cleanly from the metal.

The BS1’s cable is well made. It is an 8-core silver/copper hybrid, braided in a double-chain geometry. At its thickest, the BS1’s cable is quite hefty. It can still be easily bent though, as it is pliable. Due to having eight fairly thick cores though, it is springy and will try to return to a straighter shape if left alone. That said, it is still very easy to coil and store, and I had no problems keeping it orderly during my photo shoot.

My BS1 came terminated with a 3.5mm jack. It, like the Y-splitter and chin slider, is housed in metal. Both the jack and the Y-splitter feature black carbon fiber accents though. A nice touch that makes the BS1 feel premium.

Comfort

The BS1 is an earbud and a larger one at that. As such, people with small ears will have a hard time handling the BS1. I, however, had no problem using the BS1 for extended periods of time. Your mileage will vary according to your unique aural anatomy though.

Accessories
The BS1 comes very well-stocked with accessories. Inside the box you will find:

• 1x soft carrying pouch
• 2x packs of foam earbud covers
• 1x cable wrap
• 1x shirt clip
• 1x wooden carrying case

The BS1 has the most comprehensive accessory package of an earbud I’ve reviewed to date. Coming with both a hard carrying case and a soft carrying pouch, it definitely gets you what you pay for. Moreover, they both feel high-quality. I especially like the wooden case. It seals using only friction. The cut between the lip of the lid and case itself is so precise that it is almost airtight when closed.

Summary
The BS1 makes good on the concept of a luxury earbud. It compares favorably against its fellow earbuds, and even outperforms some full-blown IEMs in terms of treble detail retrieval. A comprehensive and high-quality set of accessories makes it a good choice for both the earbud enthusiast.

As always, happy listening!

Disclaimer:

This free sample was provided to me for the purpose of an honest review. I’m not affiliated with the company and all observations and opinions here are my own that are based on my experience with the product.

The Price:

The Penon BS1 Official is available on penon-official.com. There are 2 (two) different variants, one with 3.5mm audio plug that is sold for 99 USD and one with 2.5mm balanced plug that costs 109 USD.

Introduction:

The Penon BS1 Official earbud is the upgraded successor of the previous Experience version.

Package and Accessories:

The Penon BS1 comes in a blue and burgundy colored premium looking card box with a Golden Penon Logo on the top, which includes the following items;

• Penon BS1 Official earbud
• Wood case
• 1 pair of Hiegi foam donut eartips
• 1 pair of Hiegi foam solid eatrips
• 4 pairs of donut foam eatips
• 4 pairs of solid foam eartips
• Soft Velvet Pouch
• Shirt Clip

The Penon BS1 Official is a premium earbud and you can feel that in every detail. The wooden case and the soft velvet pouch, looks & feels very expensive and luxurious.





Design, Fit and Build Quality:

The BS1 Official is a very well made earbud with a rounded black metal shell, which has a PENON written engraving on the top. On the front is a fine metal grill that looks also of high quality.

There is a metal piece on each monitor that protects the cable like a strain relief and works also as left / right marking. This metal piece is in red for the right monitor and in blue for the left monitor.

The Penon BS1 Official sits well on my ears and the isolation is one of the best right after some earbuds with mx500 housing. You can wear it over ear and straight down and I think that the over ear method will give you the most comfortable result. There is also a bass vent on the side.





Cable:

The cable of the BS1 Official is the most premium looking cable model I have ever seen on an earbud. I remember that I was very surprised when I first saw the cable that came with the NiceHCK EBX, but this one is even superior with its wonderful looking, 8 core braided design.

This has a hybrid material construction that is made of 19 strands per core in combination of SPC (Silver Plated Copper) and Copper. It has a transparent TPU coating that feels soft but sturdy.



The chin slider is made of a circular shaped metal material that has a black painted smooth surface. The Y splitter is also made of the same material and has a carbon fiber design that has a white BS1 printing.



The 3.5mm gold plated headphone jack has a straight profile and is made of metal that shares the same carbon fiber design, which looks and feels premium. There is also a 2.5mm Balanced (TRRS) plug version of the Penon BS1 Official available that is compatible for devices like AK100II, AK120II, AK240, AK300, AK320, AK380, Cayin N5II, Lotoo PAW5000 and other sources with 2.5mm balanced output.





Specifications:

The Penon BS1 Official is a single dynamic driver earbud, that is relative efficient with it's relative low impedance of 32 ohm, which makes this earbud ideal for the usage with portable audio players or smartphones.

The Sound:

I am the sort of people who believes in burn-in and the Penon BS1 Official review is written after a burn-in process of 140 - 150 hours. I have used the stock full foams due this review.

PS: The sound performance of earbuds is very fit dependent; even more than with In-Ear Monitors (IME’s). This can be result to different experiences with the same product.







Sound Signature:

The Penon BS1 Official has a quite balanced sound signature with nice impactful bass response clear and transparent vocal presentation and nicely extended top end.

Frequencies:

The BS1 Offical has a quick and controlled sub-bass presentation, which is good in quantity and rumble. It reaches also surprisingly low for an earbud. The sub-bass of the BS1 Official extends very well and is providing a good sense of power that is rarely found on earbuds.

The bass doesn’t sound overpowered or too thin and it has the right amount at 100Hz region that gives the BS1 Official a nice hint of warmth without any loss of definition. Guitar strings in Otto Liebert’s - Up Close Album sounding quite realistic and have a nice fullness.

The midrange sounds clear and clean and there is small amount of warmness that gives instruments and vocals a nice touch of fullness, which adds additional emotion to the sound.

The level of resolution is very good for this price range and one of the best in my earbud collection.

Female vocals like Norah Johns or Saskia Bruin sounding quite natural, only some male voices like George Michael or Brian Adams sounding a hint more bold then normal.

The upper midrange has a slightly boast, but without any considerable result of harshness. Instruments sounding crisp and quite controlled and have a pretty natural presentation. The overall definition is in a high level.

The treble range sounds smooth and balanced without any loose of control. Instruments like cymbal’s in Lazarus A.D. - The Onslaught performance sounding controlled and fatigue free with all of my sources. There is a nice rendering of air that makes space for instruments.

The treble extension is in a pretty good level and the upper treble range between 10 – 12 kHz gives the overall sound a nice amount sparkle and an airy presentation.

The Soundstage and Imaging:

The Penon BS1 Official has a nice expansive soundstage presentation with a pretty good sense of space, which is especially good for songs with lots of instrument. The placement and the air between instruments are well done and the overall imaging is quite accurate in presentation. The instrument separation is great and Alboran Trio’s – Cinque Lunghissimi Minuti shows how well this erabud can perform.



Comparison with other Earbuds:





Vs. NiceHCK EBX :

The NiceHCK EBX is a very easy to drive (32 Ohm) earbud, same as BS1 Official with a nice build quality. The NiceHCK EBX earbud has a quite different tonality, which sounds brighter and less warm than BS1 Official.

The Penon BS1 Official sound fuller due the more present bass department. The sub-bass quantity is nearly the same but the BS1 Official goes lover in this register. The speed and control is quite identical on both, but the NiceHCK EBX has less extension in a small margin.

The main difference starts in the bass quantity, especially in the mid-bass department that makes the BS1 Official sounds fuller with more body. The EBX is missing some midbass that make the presentation a bit dry. The overall texture and resolution in this bass department is quite similar and there is no clear winner.

The Penon BS1 Official sounds warmer and fuller in the midrange, which makes female vocals and string instruments like guitars or violins sounding more emotional and intimate compared to the dryer and a bit colder sounding NiceHCK EBX. Both earbuds have a nice clarity and definition level, but I have notice that the BS1 Official has a touch more micro detail.

The Penon BS1 Official has better control in the upper midrange department, because it is handling female vocals and instrument that are prone to sibilance and harshness without any problem. The NiceHCK EBX has some sibilance especially with some instrument like violin, piano, etc.

The NiceHCK EBX and the Penon BS1 Official have the same level of treble clarity, but again the BS1 Official has the upper hand with additional micro detail and overall control in the upper treble range.

The NiceHCK EBX sounds quite spacious, but Penon BS1 Official is more natural and realistic in soundstage presentation. Bothe share the nearly the same level of imaging but the Penon BS1 Official is slightly more accurate.







Vs. K’S 300 Samsara Version:

The K’S 300 Samsara Version is one of my favorite earbuds together with the NiceHCK EBX and its the warmest sounding of these three erabuds.

The K'S Samsra sounds warmer then BS1 Official and needs a lot of power two show its potential due the high impedance of 300ohm.

The K’S Samsara has more sub-bass quantity, compared to the more balanced sounding presentation of the BS1 Official. The BS1 official has the better texture and control in the sub-bass department. The mid-bass of the K’S Samsara have more slam and presence compared to the more natural sounding BS1 Official.

The Penon BS1 Official sounds more transparent and clean in the midrange compared to the K’S Samsara that has an overall darker and warmer midrange presentation. The male and female vocal presentation of the Penon BS1 Official sounds more life like and has a better detail retrieval.

The Penon BS1 Official sounds more realistic with string instruments. It also performs slightly better in instrument placement and separation. The midrange resolution of this earbuds is on par, maybe little bit better wit BS1 Official that has additional clearness and transparency.



The K’S Samsara sounds softer and more controlled in the upper midrange, while the Penon BS1 Official has the better definition.

The treble presentation of the Penon BS1 Official is on the transparent and vivid side, while the K’S Samsara sounds a bit softer and darker in this department. Both earbuds sharing great control and doesn’t sound harsh.

The upper treble range of the Penon BS1 Official has more presence and sounds crisper and with slightly more definition. The BS1 Official has more resolution in the upper treble range. The differences are very small and in a micro detail level, but noticeable anyway.

Both earbuds share a decent soundstage, but there is a small difference. The Peonon BS1 Official has more width and the K’S Samsara more depth. The instrument placement and imaging on both earbuds performs wide above this price range and i think there is no clear winner.





Conclusion:

The Penon BS1 Official is one of the best or maybe the best earbud available in this price range. It has a wonderful balanced sound signature, great luxurious packaging and a decent build quality that is quite impressive for this price.



Summary (plus and minus):

+ Nice balanced sound with good detail level,
+ Decent build quality,
+ Wonderful packaging and accessories,
+ Great Price to Performance Ratio,
+ Easy to drive

- None for this price

Greetings!

Today we're checking out the BS1 Official, Penon Audio's new, flagship earbud.

Last year Penon gave me the opportunity to check out their first earbuds, the BS1 Experience. It is still one of my favorite earbuds to this day as a result of it's rock solid build quality, amazing cable, and crisp, detailed sound. Add to that a reasonable price and the excellent after purchase support Penon Audio is known for, and it was kind of a no-brainer purchase in my eyes.

Now that the BS1 Official is on the market, my precious BS1 Experience is no more having been discontinued in favor of it's final form. While this news saddened me so, listening to the BS1 Official made the loss more manageable. It costs more than twice as much as the Experience, but you are also getting a lot more ear bud. Let's check it out in greater detail, shall we?

Disclaimer:

The BS1 Official was sent over by Penon free of charge for the purposes of review. As always, the thoughts within are my own and do not represent Penon or any other entity. No financial incentive was provided to give these positive feedback or otherwise.

The BS1 Official retailed for 99 USD at the time of this review: https://penon-official.com/product/bs1-official-version/

Source:

For at home use the BS1 was powered by a TEAC HA-501 desktop amp or straight out of my Asus FX53V laptop. For portable use it was paired with an LG G5, HiFi E.T. MA8, F.Audio S1, or Shanling M1, all of which brought it up to listening volume without any effort. It's easy to drive.

Personal Preferences:

I listen primarily to various EDM sub-genres (liquid drum and bass, breakbeat, drumstep, etc.), hip hop, and classic rock. While I enjoy a variety of signatures in my headphones I generally lean towards slightly warm with elevated treble and sub-bass, an even and natural mid-range response, with reduced mid-bass. The HiFiMan RE800, MacaW GT600s, and thinksound On2 offer examples of signatures I enjoy.

Specifications:

• Sensitivity: 120dB
• Impedance: 32 ohm
• Frequency response: 14-28kHz

Packaging and Accessories:

The BS1 Official arrives to you fingertips in a compact blue and red box with Penon and their logo printed in gorl writing on the lid. The right side is imbued with a stick showing the earphones and the termination choice; 3.5mm in my case. The rear contains a company statement;

“We are a Hi-Fi company and specialized in producing high quality audio products for audiophiles”

Here is what that should say;

“We are a Hi-Fi company specializing in producing high quality audio products for audiophiles.”

It's amazing what some basic grammar and punctuation edits can do to improve overall statement coherency. You're welcome Penon.

Removing the lid of this nice little box you are greeted by a gorgeous, round wooden carrying case inset within some dense foam insert. Lift it out and underneath you find a plastic bag containing the included accessories, of which there are many. In all you get;

• BS1 Official earbuds
• Wooden storage case
• Cloth carrying case
• 1 pair of Hiegi foam donut eartips
• 1 pair of Hiegi foam solid eatrips
• 4 pairs of donut foam eatips
• 4 pairs of solid foam eartips
• Shirt clip

A few things to note. My set actually came with more than the listed number of foams, so be aware that you might get more than you bargained for. In total I received 13 sets. The shirt clip is an absolute beast and is solid metal, probably steel or some alloy. That's great because the cable is very heavy and would more than likely shatter a standard cable clip into a billion tiny chunklettes.

Overall I am very pleased with the accessory kit. The quality is quite good and you get a lot, meaning you're unlikely to need to buy more foams or others bits and bobbles down the road. My only issue is that the fabric case is too small to hold the BS1 and it's monster cable. It's really only suitable for carrying accessories.


Build and Comfort:

I would go so far as to say the BS1 Official is overbuilt. Why? Well, it shares the same durable metal shells as the original BS1 Experience, replacing the plastic driver grill with a fine metal one. Instead of being plain and brand-less, they now feature Penon laser etched into the rear of ear earpiece. They could have just printed it, but no, it's gotta be etched. The single rubber strain relief has been replaced with metal shafts colored red and blue to denote channel, thereby addressing the difficult many had determining channel on the original BS1.

Going down the cable you find it is a beast; 8 strands, 19 cores with a mix of copper and silver-plating. The splitter and straight jack are black metal alloy imbued carbon fiber. The chin cinch is a heavy hunk of alloy too. The strain relief on the jack is an inch long section of shrink wrap giving the cable tons of protection from bends and wear. All together this is a gorgeous looking and wonderfully constructed piece of kit, but damn is it ever HEAVY, bringing us to our next point; comfort.

The BS1 Experience was super comfortable as a result of it's light weight and shapely housing. Throw on a cable that weighs more than a 1979 Oldsmobile Delta 88 Royale and you can kiss that comfort goodbye. For me at least. Even taking advantage of that beefy shirt clip to take up much of the weight, my ears would get tired after 30 to 45 minutes of use. It was never unbearable, but I know this housing when saddled with an appropriate cable can nearly disappear giving you hours of fatigue free wear. That's not the case with the BS1 Official, sorry. If you can wear them with the cable over-ear, I envy you, because that would surely resolve this issue. Over ear earbuds, unless they've got memory wire to hold them in place like the OURART Ti7, just aren't compatible with my ears.

The BS1 Official is an amazingly well-built earbud, but that cable is too much, belonging on something larger and more appropriate, like a headphone. Too bad because it is easily one of, if not the nicest cable I've come across on a portable audio product.


Sound:

The BS1 Official gave me a bit of a shock on first listen. I went in looking for a snazzier BS1 Experience. The last thing I expected to hear was something so capable and comparable to those TOTL buds I had been listening to prior, those being the venerable Rose Mojito and relative newcomer Lyra Collection 32 ohm from Astrotec. The BS1 is truthfully that darn impressive and should be on any ear bud lovers “to buy” list.

The BS1 is one heck of an all-rounder with a very even, full, and lush signature. It's treble presentation is very lively and accurate with zero harshness or noticeable distortion. Detail retrieval is quite impressive which is supported by a well-controlled decay that keeps rapid cymbal notes and notes from other instruments or effects clear and well-separated. This is a very ear-friendly presentation that remains listenable for long periods.

I would have expected nothing less than near perfection from the BS1's mid-range. It's an ear bud which seem to specialize in quality mid-range presentations, and the BS1 Experience was already darn nice there. The BS1 Official does not disappoint, presenting it's mid-range with a relentless confidence. Both male and female vocals sound natural and realistic with just the right amount of forwardness. I never found myself struggling to decipher lyrics, or line to fine and rapid notes changes. Overall timbre here seems spot on.

The BS1's low end doesn't embarrass either. Like the Rose Mojito and HE 150Pro, the BS1 has a proper low end with none of the early rolloff that often plagues the format. It's bass is quick and punchy and able to hit those rumbly low notes just fine. It is very textured too, giving grungy bass notes a gritty abrasiveness you just don't get from a lot of products. All it really lacks is some visceral feedback, obvious when listening to some other buds in my collection. In the end, I have no qualms using the BS1 with EDM and bass reliant tracks because I'm getting the important low end feedback needed to carry the track.

The BS1's sound stage rolls in the same camp I put the Brainwavz B400 in; spacious but not necessarily huge (in this case by earbuds standards, not iem standard). It instead places it's talent into a few other pools, imaging, layering, and separation, which are all above average and very engaging.


Select Comparisons:

(Volumes matched as best as possible using a Dayton Audio iMM-6)

Rose Masya (109.00 USD): The BS1 dominates the Masya when it comes to build quality and overall premium feel. Metal shells vs. 3D printed plastic. Beefy copper and silver-plated cable vs. a standard black rubber cable (though it is a really nice cable). I personally find the Masya's shape more comfortable. The Masya lighter cable doesn't hurt either.

BS1 has a fuller, more balanced sound as a result of greater mid-bass presence, but falls short of the excellent end-to-end extension of the Masya. Masya's mid-range is more crisp and prominent with a slightly cooler tonality. Treble detail is similar with the Masya pulling slightly ahead. Bass on the BS1 has a mid-bass focus while the Masya has a more sub-bass tilted response. Masya has a wider and deeper stage with a more visceral presentation. The BS1 sounds smoother and more refined.

Rose Mojito (259.00 USD): Everything I said about the Masya vs. the BS1 in terms of build and comfort hold true here since they're also crafted from 3D printed plastics and identical in dimensions. The Mojito's stock cable is even worse though. We're not going to talk about it. Rose's upgraded cable I've got on mine is much lighter and more flexible than the BS1's, and therefore much more suitable to a portable product in this class.

The Mojito presents itself like a headphone while the BS1 comes across as a very good earbud. Mojito has deeper, more impactful and physical bass. Like the Masya, it has a larger, more open and spacious soundstage, though I found the BS1 slightly more accurate in terms of imaging. Treble is more prominent and detailed on the Mojito. Rose's mid-range is more forward and dynamic.

Astrotec Lyra Classic (139.00 USD): The Lyra Classic shares the same gorgeous shell with the Lyra Collection, therefore it is wonderfully crafted aluminum with more style than you can shake a stick at. It's about equal in comfort and ergonomics to the BS1, but pulls ahead once again due to use of a lighter cable. The Classic's cable is pretty mediocre though, being that it is pretty much identical to what you find on a 10 USD Knowledge Zenith. Great for 10 bucks, not enough for 140.

Like the Masya, the Classic is more treble and mid-range focused than the BS1. Along with a thinner presentation, it is more detailed and has a more spacious stage. Bass again has a more visceral feel to it than what you get from the BS1, yet it remains quite lean. BS1 is the better all-rounder whereas the Classic excels with vocals.

Final Thoughts:

If you've been on the fence about getting the BS1 Official, just go for it. This is a top of the line earbud in build and sound for a fraction of the price of similarly performing products. It's a no-brainer really. Just be prepared to deal with that gorgeous, heavy cable. If you start exercising your ears via pull ups and crunches at the time of ordering, they should be plenty buff enough to handle the weight of any ol' cable by the time the BS1 arrives on your doorstep.


Thanks to you for reading, and thanks to Penon for the chance to check out this lovely earbud.

Spoiler: Just a German preamble before the full English review

Vorwort:

Introduction:

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:

https://penon-official.com/product/bs1-official-version/
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.


Sound:

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.

Tonality:

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.

Resolution:

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.

Soundstage:

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.


Conclusion:

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.

Introduction

Penon is a Hong Kong company that produces iems, earbuds and cables. They started out with their first earbud in the Penon BS1 Experience Version. Recently, they have released the Penon OS849 cable which I have reviewed earlier. In this review, I will be reviewing their latest earbud in the Penon BS1 Official Version. At the moment, you can purchase the Penon BS1 Official Version from https://penon-official.com/product/bs1-official-version/ .



Specifications

• Driver: 15mm dynamic driver
• Impedance: 32ohm
• Frequency response: 14Hz – 28 kHz
• Sensitivity: 120dB

Unboxing & Accessories

The BS1 Official comes in a red and blue package with Penon printed on the front cover in gold colour. After opening the package, there is a wooden circular case that contains the BS1 Official. Beneath the case is a soft carrying pouch that contains 2 packs of foams, cable wrap and shirt clip.





Earbud Build & Design

The BS1 Official has the Penon brand name printed on it in grey colour. The shell has a smooth matte black finish to it. It has a circular shape. The housing is made of aluminium. The strain relief has a blue and red housing to differentiate between left and right respectively. There are 3 vents at the bottom of the housing. The earbud is constructed well.









Cable Build & Design

The cable has a 8 core design and it is braided well. It consists of 19 strands per core and the material is a combination of copper and silver-plated copper. Moving down to the chin slider, it is black and circular in shape. The y-splitter has carbon fibre design and sports the model name in white colour. Lastly, there is a gold plated copper straight jack and the housing has carbon fibre on it with strain relief. There is the brand name printed on the housing. The overall cable design gives a premium feel and I find it aesthetically pleasing. The cable is quite soft and supple for a 8 core.



Sound Analysis

Lows

The BS1 Official has good sub-bass quantity and there is a nice boost. The sub-bass is being extended with a nice depth and there is a speedy rumble. The agility helps to inject excitement into the sound. There is a good display of technicality and the decay is pacey. The mid-bass on the BS1 Official has a moderate amount of quantity and the slam has enough weight for an impact. There is a strong control in its bass presentation. The combination of quantity and agility is able to produce a harmonious performance. Bass texture is smooth. The articulation is quite accurate. The approach the BS1 Official operates on presents the bass with speed and body.

Mids

The BS1 Official has a gorgeous midrange and it is displayed with excellent finesse. The midrange is able to tackle vocals with ease be it male vocals or female vocals. There is richness in the mids due to the body. Vocals are presented in a very intimate manner and the body helps to improve the realism of it. The lower mids has a great quantity to it and male vocals are being expressed without sounding hollow. It is able to convey emotions well. For the upper mids, there is body to it and it is presented with forwardness. Along with the crisp, there is a nice organic presentation. Female vocals are being displayed with intimacy and the definition is excellent. There is a high standard of details retrieval.

Highs

The treble is extended with a good depth. It packs details and there is clarity. There is no sibilance and harshness. The treble takes on a full-bodied approach with accurate articulation. The amount of air rendered has a great amount and this helps to allow the lighten the presentation which complements the overall full-bodied sound. There is a great definition to it.
