    Brilliant Introduction to Audiophile Music
    Written by biggysmalls
    Published Apr 28, 2015
    Pros - Sounds amazing through any source. Flexible with any music. Astonishing clarity.
    Cons - Headband has too little padding and the plastic used is cheap feeling. Slight sibilance.
    This is my first audiophile grade headphone and I truly believe that this is a brilliant introduction to how awesome music can sound!
    I live is South Africa, a country that is renowned for ripping off it's consumers. With the dwindling value of our Rand, I had resigned myself to asking a friend to bring a pair of headphones back from USA or Europe. Local prices of headphones and any audio equipment are exorbitant. 
    With a heavy heart and a patient wallet, I waited for word from friend until one day a local site had them on an incredible special for one day. I bought these off of an extremely good site called onedayonly.co.za for a price of R1899 ~ $160. Incredible!
    When I received them I was absolutely blown away by the look of them. Wood does amazing things to people's perception of quality, but it's a bit of a pity that I can't say the same for the plastics used. I know that these are made of recycled material. Regardless, everyone I showed them too were blown away by the look, and said that they'd never seen headphones made of wood like this! It would have been nice if these had come with a hard case as the provided hemp bad doesn't give me confidence in transporting such beautiful headphones. Minor gripe, but one worth mentioning.
    The padding on the earphones are more than adequate, with lush memory foam and synthetic leather that I can pass off as real leather :wink: the only issue that I have with them is that the headband padding, while looking more than sufficient, seems to separate at the ridge that runs down the middle of my skull. What I mean is that the quality of the foam seems to be lacking, and as a result it gives way to the weight of the headphones and compresses to the point where I can feel the metal band in the headband. I have a little bit of bruising in the week that I have been wearing them, but I've decided to take a teaspoon of cement and toughen the hell up because I can hardly take them off! This leads me to the sound ...
    Ladies and gentlemen, load your weapons, because what I'm about to say will surely anger you ... I am using my 8 year old Logitech X-530 headphone jack as my source. Straight onboard produces too much emf noise. As I said, I'm just starting out in the world of audiophile music and haven't been able to get a decent source. With the price of just a Audioquest Dragonfly 1.2 going for what equates to over $350 here, I've shifted my goal to the $150 Meridian Explorer that I'm hoping my girlfriend's uncle can bring back on his next business trip (If any of you are headed to SA and would like to do me a solid, send a PM :wink: ).
    On to the sound: Absolutely brilliant! Despite my cringe worthy set up, I have been floored by the quality and separation of the music. Everyone that I play this for literally have their jaws on the floor. Now despite my avatar name of biggysmalls (neighborhood nickname growing up) I listen mostly to folk, rock and acoustic. With Foobar2000 installed I've been listening to FLAC albums of Queens of the Stone Age, Milky Chance, Sam Smith (who sound amazing with these), Noah and the Whale, Beck, Queen and Taylor Swift. A SA band, Al Bairre, who releases all their music in high quality recordings have also been high up on the list. All of them sound as what I imagine they were meant to sound. These are extremely versatile headphones that will adapt to whatever you decide to throw at them. From the bass to the treble, the movement is very fluid and nothing seems really accentuated. I'm not a bass guy so I'm very happy that the bass, while slightly accentuated, is not overblown.
    I'm not going to throw fancy words around because I honestly would probably make a fool of myself amongst such professionals that frequent this site, however I can say that I've gone from someone who almost never listened to music through headphones to being the permanently glued to them. One minor issue I have is that there is very slight sibilance. Very minor, but I'm hoping to kick these babies into the next level when I eventually get the Meridian Explorer in the coming months! Update to follow!

    Thinksound On1: Excellent Eco-Friendly Headphones On-The-Go
    Written by YoYo JoKeR
    Published Apr 23, 2015
    Pros - Excellent Neurtral & Airy Sonic Presentation, Eco-Friendly, Portable
    Cons - Rough Plastic Edges

    Me: I am a 21 year old student living in a small town in India. I would like to call myself a music enthusiast, rather than an audiophile. I was inspired by music since childhood, and as the time passed, the passion of music grew in me, and that subsequently led me to join Head-Fi. Eventually, I found the pleasure of listening to music mainly by the HD600 and recently, by the seductive LCD2 headphones, and realized the true components of recorded music. I usually like to listen to Indian Classical Music along with Bollywood songs. My main listening genres include classical, vocal, instrumental, jazz and sometimes pop.

    Intro:  Thinksound is a new US brand specializing in the area of headphones and IEM’s. They are based in Somersworth, NH. Their products are all designed & developed in the U.S, but made in China by high standards. ON1 is the On-ear Closed-back headphone offering from Thinksound.
    Thinksound has a specific vision in making their products: The products should last long and must be made up for eco-friendly materials. Infact, Thinksound is the first brand which has taken up such environment friendly initiatives in audio industry. Currently all of their headphone and IEM lines are closed back, solidly built by wood, fabric & cotton components, and all of them have a very natural and musical listening experience with them. Mr. Aaron Fourniner is the founder and Chief Executive Officer of Thinksound.
    Specifications of the On1:
    Type: Closed back, On ear with Passive Noise Isolation
    Driver: 40mm dynamic
    Frequency Response: 5Hz-22 kHz
    Impedance: 50 ohms
    Hand crafted wood housing
    Plug: 3.5mm steel reinforced gold plated
    Cable: Kevlar® reinforced, tangle-resistant fabric cable
    Earpads: Memory Foam Pleather

    Let us see what the On1 has got for us,
    Packaging and Accessories: The On1’s arrive packed inside a strong cardboard box with a removable outer sheet, on which features and other information have been mentioned upon. Once the box is lifted open, The On1 is seen resting. The layer of cardboard can be lifted off to reveal another storage compartment, in which cotton pouch and user manual are present. Packaging is very eco-friendly, which reduces synthesized materials as much as possible. Thinksound has done some really innovative and eco-friendly packaging out here. Even the small velcro is made up of natural cotton material.
    List of accessories in the box, which include the following: 
    Fabric Cables:  One short 1.25M four pole 3.5mm audio cable with mic and volume controls, and another regular 2.0M cable.
    Cotton Headphone Pouch: This pouch has a eco-friendly finish to it, and functions as a storage pouch for the On1.
    User Manual: Contains instructions to operate the On1 and other warranty information.

    Design and Build: The On1 has a very good overall build quality, except a few areas where the plastic arms are not finished well and give out a finnicky look.
    The entire housing shell is made up of high quality Wood, and is well polished and coated. cans are pretty small, and appear to be large in pictures. These are light in weight. Thinksound logo is printed on the rear side of the housing shell. Left and Right markings are particularly easy to see, and are clearly indicated. Headband is made up of natural sewn cloth. Earpads have pleather material as cushions.
    The On1’s are already nimble, easy to handle, wear on and power requirement is low. Along with all these, these are fold-able, and are easy to carry around. On1 has a common 3.5mm cable socket, hence the cable is of very common type, a 3.5mm audio interconnect. This ensures, even if the current cable breaks, a replacement is easy to obtain, any 3.5mm cable audio cable will fit in. One downside I observe here is, wiring for opposite driver is embedded on upper end of headband, and through yokes and into the housings.
    Cable has a very good build. It is light, flexible and does not get tangled. I could not notice the presence of any microphonics. Plug is straight and gold plated. Both ends of cable have same connectors, thus the cable can be used either way: topside down or vice versa. The stock cable does a great job in transferring signals along with great transparency, but the stock cable provides a slightly  ‘thin’ sound delivery, and this can be changed for any optional upgrade 3.5mm cable, which are are very easy to obtain under 15$.

    Comfort:  ON1’s are very comfortable to wear in general, and its yoke is long enough and hence comfortable for almost any-sized heads. On1 is ergonomically designed. But since the earpads are madeup of pleather, ventilation will be less, thereby causing sweating; especially in tropical climate. But it can be continuously worn over an hour without any discomfort issues.
    Since On1’s are closed back headphones, these will isolate the listener from outside noise. This level of isolation is very good for a traveller. Going by weight factor, these feel really light and very easy on head. Clamping force is relaxed and not at all imposing and pressing against ears. Headband has a good cushioning, but it can dirty quickly due to its fabric nature. Also, the On1’s housings have high degree of rotation, ensuring a good comfort for any given heads and ears.

    Sound: As for the most important part, the On1 has a very neutral, clear & airy sonic character. It is very transparent and detailed. We have to keep in mind that, with on-ear headphones, sonic presentation may feel different with different fit. Therefore fit/angle is the deciding factor for sound being perceived by ears.
    Burn in: These improve a lot with time. Let’s say a playback of 20 hours provides major audible improvements, along with softening of pleather earpads and better clamping force. Bass prior to break-in is slightly looser, and eventually it becomes more accurate, Mids will sound more open, airy and natural. Highs become slightly smoother; soundstage opens up by a margin.
    Lows: are accurate, tight and refined; have a strong impact. Depth is very good.
    Mids: sound very neutral, airy and clear.
    Highs:  Detailed treble with slight grains and sparks. Unforgiving on bright recordings
    Soundstage: Unlike majority of portable cans, the On1’s soundstage is more airy natural and circular soundstage. Depth is excellent. Instrument separation is very good.
    On1 portrays music in such a way that, one feels as if the music is all around him (excellent soundstage for a portable closed can). According to my observation, these cans sounded good in all genres I tried, and hence I also observed these are unforgiving to poor recordings. Hence these are appreciably transparent in character. The On1 sounds almost like open headphone, very airy, a vast 3D like soundstage.
    Instruments placement & positioning is great.  I wouldn’t call On1 a natural sounding, but as neutral, detailed, transparent. Its resolving power is very good and worth mentioning.
    Low volume listening is pretty impressive. One can hear On1 in very low volumes, yet it retains all the details & elements present in a track.
    Comfort and fit plays a vital role in sound being perceived to our ears. Especially in case of On1 where the earpads are very compact, if they fit in a wrong way, they will leak sound leading to missing details.

    Amplification: The On1’s are rated at 50 ohms, and designed to be power efficient, and hence are fairly easy to drive, and can be driven by almost any sources, smartphones and DAP’s. Although setup like an O2/ODAC does indeed increases accuracy, soundstage and dynamics, and the difference in quality is clearly audible. Power is not very important aspect here, but a transparent setup indeed does help in increasing SQ;

    Conclusion:  I feel the On1’s are a very special and unique set of cans. Build quality is phenomenal, sonic presentation is very pleasing, with fairly good soundstage. I really like to listen to these cans. I have nothing but praises for the On1. The On1 is also a very responsible headphone when it comes to environment; it is designed as eco friendly headphone with recycled packaging box, cotton pouch.
    On1 also minimizes the use of artificially used materials like plastic. The idea implemented is very again very inspiring & may lead to major manufactures to make a similar move. Overall and satisfactory and excellent purchase for an On ear headphone. The On1 is available at amazon for 200$ and performs excellent when related to its price, and is worth every single penny spent. 
    1) Build Quality: The On1 has a good wood/metal/plastic build, and is more environment conscious than majority of its counterparts.
    2) Sound quality: Sound presentation here is very neutral, detailed, & airy, it is very much like-able and fatigue free for music listening.
    3) Power Requirement: On1’s can run off on smartphones without issues, and still sounding very good. Amplification or source requirement is comparatively less. One can satisfy the hunger of ON1’s’s with just a cmoy amp.
    4) Eco-Friendly: As per my memory, Thinksound is the first brand which has been manufacturing headphones while keeping environment safety in mind. It is not very easy to do the same in current industrial situation which focuses mainly on Plastic/Fibre.
    Rough Surface: The plastic finishing in the outer body of headphones is not well done, and gives rough edges and finicky feel. I hope Thinksound will improve the On1 in this regard.

      Oh oops, my bad. Sorry bout that @YoYo JoKeR and @Brooko. I must have seen it somewhere else and I did try the rain2's as well and I actually liked them better than the On1. Again, I think I need to audition the On1 once more because I'm afraid it just wasn't burned in / I had bad fit.

    Aesthetically and Sonically Pleasing
    Written by Pacal
    Published Dec 17, 2014
    Pros - sound quality, aesthetics, detachable cable, sustainable philosophy, comfort, headband durability
    Cons - stock (braided and therefore textured) cables can be noisy if rubbed against fabric (ex. shirt collar), can be uncomfortable when worn with glasses
    These headphones sound very precise and balanced. You will hear your music as it was recorded, mixed, and mastered which is the approach I prefer to trying to find headphones that try to EQ things for you. I listen mostly to metal, jazz, synthpop, and instrumental music and the On1s have impressed me in everything I've tried. They can get very loud when powered from a PC and sound great straight from my Nexus 5. The wood used to make the cups is very beautiful and pleasant to the touch. They change color slightly depending on viewing angle and lighting which is cool; much more classy than red and white plastic. The headband is comfortable and quite durable; you can find a youtube video of it being stretched and twisted to no ill effect. The included cables are also pretty. The one with the inline pause/play and microphone works well for phone calls/skype when used with a smartphone. They also did a decent job of muffling noise while I listened to podcasts on a flight recently. Strictly passive noise cancelling obviously, which may vary in effectiveness depending on the size and shape of your ears.

    Some things to note: they are quite comfortable but can cause some irritation if you wear glasses with them for long periods of time. I've found that moving my glasses up a bit sidesteps that issue. This issue is inherent to on-ear headphones, so nothing against this model in particular. While the braided cables are pretty they can cause some noise when rubbed against other fabric surfaces, such as my shirt collar when I'm sitting at my desk at work. This can be avoided by using a different non-braided cable or by not wearing shirts with collars I suppose.

    Ultimately I think these headphones are worth the money as they sound, look, and feel great. Those who appreciate quality, unbiased sound across wide varieties of music and portability will find their money well spent on the On1s.

      Nice write up Pacal. I was curious if you could give a little more description with how they perform with the genres of metal. I've heard for the most part they do well representing most genres however when it comes to distortion on guitar, its somewhat inaccurate.

    Thinksound On1 - Portable Woody Perfection
    Written by Loquah
    Published Nov 22, 2014
    Pros - Beautiful wood finish, warm detailed sound, excellent soundstage size
    Cons - On ear headphones are never comfortable for longer sessions, some of the plastic finishes don't look great
    Thinksound is a company that’s focussed on sustainable and environmentally conscious headphones. In fact, they even offer a recycling program for headphones with a bonus if you recycle their headphones, but I doubt you’ll be doing that any time soon with the On1s – you’ll be hanging on to these puppies with everything you’ve got!


    Thinksound’s On1 headphone is a foldable, portable, closed, on-ear design that retails for roughly $350 (AUD).
    1. Frequency response:  5 – 22,000 Hz
    2. Impedance:  50 ohms
    3. Drivers:  40mm dynamic
    4. Cables:  4.5 feet (2 equal length cable options with / without phone mic and remote)
    At $350, the On1s are competing with some outstanding competition from the likes of AKG, Sennheiser, Beats, Kef, Focal, and various other brands, but they more than hold their own with their sound and offer something unique with their striking timber finish.

    Design & Comfort

    Other than the wooden cups, [​IMG]the design of the On1s is not particularly special, but that’s not a knock on them so much as a simple statement of fact. They are a fairly traditional design with a simple, adjustable headband and swiveling and folding cups, and that’s about it. The wooden cups are engraved with the Thinksound logo, but other than that these headphone don’t really stand out as looking like $300+ headphones – they’re not blingy or flashy and that’s fine by me because they won’t draw attention to themselves or to you and that means you’ll be left in peace to simply enjoy the wonderful sounds caressing your ears.
    Some may find the basic looks and finish of the plastics in the On1s to be a bit of a turn-off, but I would definitely encourage you to take a listen before letting that dissuade you. The finish isn’t poor in my opinion, but it also isn’t polished in the manner of something like a Sennheiser Momentum or Beyerdynamic DT1350. The fact that I’m reviewing the On1s though, and not those other products, tells you how much the finish impacts the overall enjoyment of these headphones thanks to their adequate finish and the exceptional quality of their sound.


    The On1s are supplied with a carry pouch made of a natural cotton along with 2 different cables, both of which are high quality, Kevlar reinforced affairs that feel high quality and resist tangling very well.
    You can purchase replacement ear pads from Thinksound if required, but that’s really the only other accessory I can think of for the On1s.


    [​IMG]The On1s are designed with earcups that swivel to sit flat and also fold inward towards the headband. This means that they can be swiveled and folded into quite a small package. All the joints and moveable parts feel sturdy and solid despite being plastic so the end result is a compact, robust portable headphone that fits nicely in a bag. My only complaint about the folding design is that when the headphones are placed flat on a desk they are the wrong way around. What I mean is that the left earcup ends up on the right hand side if you lay the headphones flat on a table with the padded side down (see images). This is a really minor issue, but it does mean you have to turn the headphones around when you pick them up to put back on your head. It’s not a deal breaker, but I’d much prefer if they just swiveled in the other direction.


    Comfort with the On1s is pretty good, but they’re still an on-ear so I do find they physically fatigue my ears after an hour or two. Design-wise I think they’re just right from a comfort point of view – they use nice soft, memory foam pads and a good level of clamping force so they’re about as good as an on-ear can ever be and there’s no way to make a headphone this portable if it’s over-ear so no complaints here.


    I’ve already described the Kevlar reinforced cables so the only other things to mention are that Thinksound cleverly kept the phone controls simple enough that they work with most phones, including Windows phones!
    The cables are a good length at 4.5 feet (roughly 1.3m) and use a simple 3.5mm mini jack so you can very easily replace the stock (non phone control) cable if you want to. You can see the 3.5mm socket on the right ear cup (shown on the left in many of the photos due to that folding issue I mentioned).


    [​IMG]This is the bit that really sold me on the On1s, but, if I’m completely honest, the first time I heard them I wasn’t particularly impressed. That was my error, not theirs. The overall sound of the On1s is quite smooth so their quality may not jump out at you on first listen, but relaxing into their slight warmth will reward you with a purely enjoyable experience of accurate, detailed sound presented in an endlessly listenable manner so give them a moment and sink in…


    The On1s go deep, very deep.
    One of my favourite test tracks for bass is A Thousand Years from Sting’s “Brand New Day” album and the On1s very accurately convey the massive, sub-bass rumble to start the track and then display appropriate control over the bass line as the song continues. They’re not quite as refined as a top-of-the-line full-size headphone, but the simple fact that they’re close enough to consider that comparison is testament to their very impressive bass performance.
    Another track I threw at the On1s is Morning from Beck’s “Morning Phase” album because it presents the challenge of some long, held bass notes at the same time as some drum hits for shorter bursts of bass. Once again, the On1s handled the subtle and not-so-subtle with grace and control. They’re not quite ballerina agile, but they’re also not sluggish or slow. The On1s strike a great balance between smooth, very slightly rounded bass and punchy, controlled bass. For a portable headphone I would much prefer this sort of tuning because it lends itself to use in louder environments and for a wide range of genres (including movies) so the On1s are right on the mark.
    In terms of overall balance in the bass, the On1s are pretty balanced. They boast great levels of sub-bass, but also excellent punch in the mid-bass with no glaring peaks or troughs anywhere to be heard. They probably have a bit of a lift in the mid-bass to give them their sense of warmth and punch, but it’s nicely balanced with everything else so I’m in full favour of that decision.


    [​IMG]To me, when the mids are done right they’re hard to describe – not in-your-face and not recessed, not raspy and dry, but not creamy and thick. That’s what the mids from the On1s are like – just right. They are well-placed in the mix, but aren’t emphasised so everything just falls together into a cohesive auditory “picture”.
    In the overall balance of things, if I absolutely had to make a call, I’d say the mids are slightly less energetic than the bass and ever-so-slightly warmer than neutral, but all in a good way. The On1s are in no way over-polite, but they are incredibly smooth and friendly. They won’t gloss over a crappy recording, but they also won’t scream and shout about it.
    Throughout the mid-range frequencies, the On1s often surprise me with little details that I didn’t expect from their overall presentation – a guitar lick here or a drum strike there. The way these headphones deliver everything to your ears, but without making a song and dance about it is quite exceptional. I guess, as I think about it, the presentation from the On1s would best be described as speaker-like in all the best ways possible.


    The overall shape of the On1′s frequency response chart would probably resemble a beginners ski slope so the treble is rolled off slightly, but does so in line with the other frequencies so there are once again no glaring peaks or troughs to attract your attention away from the music. The treble is clean and detailed and not overly polite, but as per the theme of this review so far, there is a refinement and smoothness to the treble that allows it to caress your ears with sound rather than scream and shout.
    Consonants from vocals have enough energy to be crisp and clean, but never sibilant and cymbals crash and splash with a natural sense of energy that once again reminds me most of a good set of speakers and that’s about as good as it can get for an enjoyable set of portable headphones in my opinion. Sure, the On1s may not reveal details in the same manner as a pair of HD800s, but they’ll be far more enjoyable to listen to when you’re listening to a wide range of sources and genres in a wide range of environments so the treble is perfect to my ears for this sort of headphone.

    Staging & Imaging

    [​IMG]I think Thinksound could have called the On1s the Thinksound Tardis if they had wanted to. These things have uncanny imaging for what look like basic, portable earphones. Despite the lack of angled drivers or other acoustic tricks to help imaging, the On1s are one of the best staging and imaging headphones I own and they’re closed!!
    The stage thrown by the On1 extends beyond the ear cups, has excellent height and is even borderline for projecting sound beyond the boundaries of the forehead – that’s pretty impressive in my book!
    Each instrument from the On1 has well-defined space in the soundstage, including a sense of weight and presence that adds to the ambience and enjoyment of the music. The overall presentation of the On1′s stage and image is actually quite holographic and never ceases to be a source of enjoyment for me when I listen to them with any genre.


    [​IMG]At $350, the On1s aren’t a cheap headphone, but in my experiences they perform at a level that’s easily twice their price. These have quickly become my favourite closed headphone of anything I’ve listened to (including flagships like the Fostex TH-900). I’m not suggesting that the On1s out-perform flagship headphones across the board, but they do present a uniquely coherent sound that is just so easy to get lost in because nothing is noticeably highlighted or flawed, but they’re also not bland in any sense of the word. No, the On1s are engaging, lively and enjoyable, but they do it all in ways that are hard to pin down.
    Writing this review has actually been very challenging because the On1s don’t really stand out in any one way, but they stand out overall. It’s hard to pin anything down with them as being excellent (or flawed), but the overall result is nothing short of brilliant. I’m worried at this point that my blow-by-blow sections above don’t do these headphones justice so I’m hoping this summary will. These headphones are exceptional, amazing and outstanding. No, they are not detail freak headphones like HD800s (for example) and they aren’t completely neutral because they have a definite sense of warmth and bass, but they are just so completely enjoyable and versatile that I have a hard time imagining someone not enjoying these.
    If you’re in the market for a portable (or non-portable) closed headphone, please do check out the Thinksound On1 before you buy anything else – it might be the best move you ever make!

      Great review Loquah, I have very similar impressions as these always impress whenever I listen to them.
      You can never put a finger on what it is but there is something about these headphones.

      A good, informative review.  I'd give these more consideration if Thinksound stopped pushing the environmental BS and didn't use it as an excuse to include a bag that provides no protection as opposed to a hard case.

    Great sounding on-ear headphones
    Written by zazex
    Published May 11, 2014
    Pros - Warm, rich, detailed overall; solid articulate bass, very comfortable, nicely made
    Cons - Excessive ibilance with stock cables
    This is an UPDATE of my original review.  Listening further, experimenting,
    taking suggestions from the comments.
    My original rating was 3.5, because these headphones do - as noted - display
    clearly audible sibilance wherever it can possibly occur.  
    Some comments suggested using aftermarket cables, and I did so.
    The sibilance disappeared.
    Most recently, I've been using these with a plain cable offered by V-Moda.
    Straight, light, and reasonably priced.  (I tried 5 different cables in all.)
    While IMO thinksound has to bear responsibility for bundling a cable
    with these headphones that degrades their quality, the fact is that
    aftermarket cables are widely available - and thinksound did "think"
    to use a standard 3.5mm input, allowing the use of many different
    And, with the V-Moda cable (and others mentioned in the comments
    below), these headphones sound superb, easily holding their own
    sonically with any of the competition.  Rich, warm sound, highly
    detailed, great dynamics, and a superior soundstage.  
    They're also very comfortable - one of the more comfortable
    on-ear designs I've worn.  
    They have a solid feel, and the wood earcups look terrific.
    At $260.00 or so there's plenty of competition - e.g. the Beyer T51p,
    the NAD HP50, the KEF 500.  But the onOne's compete very well
    indeed.  I recommend listening to them if at all possible (with an
    aftermarket cable at the ready).
    And withal, I'm raising my original 3.5 rating to 4.5.
    Comments, jeers, cheers, all welcome.
    ORIGINAL review follows:
    It will be a short review.
    I was excited to find these headphones, since I had use for a closed on-ear set of reasonably high quality.
    I had the Senn Amperiors, but IMO their bass was too much.
    I'd had the Senn HD25 1 II, but the clamping pressure was too tight for me - also, soundstage was small.
    Looked at the new aluminium Senn HD25, but they didn't seem to be 'wowing' anyone at $329.
    KEF 500 looked OK, but I noticed the pads are flat - and flat pads generally bother my ears (physically).
    B&W P5, P7 - thought I was paying too much for bling type materials e.g. leather (plus the name).
    (I happen to be a fan of B&W speakers, own them, (2 pairs).
    Then I saw these Thinksound headphones, which I remembered vaguely from a review.
    Bought them (brand new).
    Initially, out of the box, I was delighted.
    They did pretty much everything well.
    Sounded bigger than most closed headphones,
    beautiful and very nicely made,
    a rich sonorous sound through and through.
    Punchy dynamic bass (perhaps even slightly too much for some listeners),
    smooth, coherent; soft yet detailed treble.
    The cord was microphonic but with all I'd looked at, it seemed nitpicking.
    I figured I'd probably just get another cord.
    And then > [​IMG]
    Sibilance!  On one of my top test albums, one Id listened to hundreds (thousands) of times
    Female, mezzo, "s"
    Then I heard it again, this time on a "t"
    Not happy about that.
    Listened to a couple more albums that I use for testing and know very well,
    ...sibilance on every one.
    And not a small, "I can live with that" sibilance,
    but a strong, "Here I am" sibilance.
    After burning in the headphones for about 10 hours,
    I listened to them again for a few days off and on
    using a different playback system.  
    Specfically, a DX50 > O2 (FLAC files only).
    It was a bit frustrating because the headphones continued
    to sound great but for that blasted sibilance.
    Reluctantly, I've packed them up and
    will return them to the seller on Monday.

      Interesting review. Thanks.

      I've haven't heard them yet but I actually own their stock cable without the remote, which is built well and sounds fine with other headphones such Focal Pro and T50RP.

      Great review, thanks. Just wondering if anyone has had the chance to compare On1 with ATH-ESW9.
