I didn’t expect how good these would be despite being repeatedly told that by reviewers. My previous experiences with AT headphones has been underwhelming and these don’t align—they’re simply sublime. They have a seemingly magical ability to pull sounds from where there were none, and defy your expectations of what a smallish portable headphone is capable of. The cable connectors are a little fiddly but lock in well—time will tell if they have durability as the proprietary cable is pricey to replace, but that’s for down the road. The only knock against them is use of just slightly cheap feeling plastic in some spots and the worthless bag. You’ll want to get something sturdy to protect your sizable investment. Personally I’ll never get rid of them—they’re the end of my search for closed portable headphones.

I upgraded to these from the MSR7NC's and I'm not disappointed at all. I look for female vocals and overall clarity of sound in headphones the most. As an audiophile it's satisfying to hear instruments and other sounds in the most accurate and clear production possible and these are excellent at it. These render instruments in a precise, realistic way and it's really satisfying to hear any kind of instruments with these headphones. I've never heard instruments be this accurate before from a pair of headphones, these just excel at it. They are also a slightly V-Shaped headphone but the key is slightly, not fully. Their vocals sound awesome, especially female vocals. The vocals and the overall sound is bright and sparkly while not being exhausting at the same time. The MSR7's were too bright in my experience, the brightness was enjoyable but it would also get tiring. The WP900's have a perfect balance of being bright enough to bring out vocals and have a fun, sparkly sound while at the same time not being tiring for your ears. I can listen to any already bright songs on these for as long as I want, while on the MSR7NC's I would get tired after only 30-60 minutes of listening to bright songs. Even though these are slightly V-Shaped, the vocals on these are actually amazing and sound better than my MSR7 cans, which are known to be really bright with vocals. The vocals are just more clearer and more natural sounding, and they still get brought out especially when it's anything with female voices. The sound overall is perfectly clear and I'm hearing sounds/instruments I've never heard of in the same songs before. They bring out every single detail a song and render the song exactly how the artist intended it, without overdoing anything. The MSR7's were not too neutral as they were overly bright, and these are definitely more neutral sounding. The WP900 also has the minimal bass you need for music such as hip-hop. The bass in these is solid and comes out as natural when needed, but it's not overdone like on many other headphones. These don't have thumpy bass like so many other headphones so if you're looking for headphones that will thump your heart with bass these are not for you. However, their bass is still there and more than enough for people who aren't bass-heads. There's also a good sound isolation and these also block outside sound well without having anything weird like ANC in them.Overall the sound is awesome for anything, but it is especially awesome for anime, feminine songs and movies. And even more for a feminine anime voice/vocal.The soundstage is the best I've heard in a closed-back. These also excel at it and there's great instrument separation. If you're coming to these from an open-back, you probably won't be dissapointed in how good the soundstage is.The sound signature is a fun, unique one. These will sound really weird at first and hard to listen to, but that's because the sound signature of these is not like other headphones. These have a special sound render that can make any song more fun to listen to while sounding accurate and clear. You just have to burn into them. It's real and the more audiophile a headphone is the more weird they sound at first. These have the same specs as other high-end/expensive audophile level headphones and there's a lot going into your ears, even though you can't process all of those frequencies. They sounded really weird to me at first and I even thought of returning them when having them for the first few days, but after about 2 weeks of using them I was getting used to their sound and that's when I realized I made the right choice to not return them. I was having an orgasm to my ears with how great these sounded to me, after I was starting to get used to their sound signature. As more time passed by, I was enjoying them more and these headphones have got me to listen to music all day. Now after having them for 30 days, these are like an eargasm to me everytime I put them on. When you get these, they'll sound strange at first but just let yourself and your ears burn into them before judging them. Amazon gives you 30 day returns, so you have plenty of time to get used to their sound and determine if you will enjoy them. Just give it a try for at least three weeks and trust me, you'll be happy.I recommend using a DAC with these, they do not need much power so there's no need for any AMPs and you can easily use these with any smartphone or any device in general. I still recommend a DAC with these just to get the best out of their amazing sound. You don't need to use the balanced wire that comes with them, but using a DAC to render audio will help you get the best of any audiophile headphones in general, not just these.Anyways enough about the sound. The sound is excellent, but that's not the only advantage you're paying for. The wood on these headphones just gives a feeling I cannot forget. It looks beautiful, it feels premium and makes you feel like a classic person. Once you feel the wood in person you can just never go back. Wearing these outside will bring you attention from people and it will put a good impression because these just look so great and appealing. You not only get amazing sound with these, but you also get amazing looks and feel while wearing these classy cans. The wood and design overall is what makes it unique and more on the old fashioned side.These are also fully comfortable. They are light like a feather and you will forget you're wearing headphones often. Their earpads are comfy and will not create any pressure on your ears no matter how long you wear these for. Even the MSR7 cans, which have thicker earpads than these can hurt my ears but these never do.The only downsides of these I can think of is the wires they give are a little short and the padding on top is thin, but those are just minor and not much compared to the positives about the WP900.I highly recommend getting these if you want sexy audiophile headphones that have fantastic sound and are also fully portable at the same time. These are probably the best portable headphones you can get, because they push the limits with how good they sound, while being portable and working anywhere with any device, and having no requirement for external power.

It doesn’t press as tight as I would like on my head to get a better bass response. Like the sound sig but unfortunately, I wouldn’t be able to fully experience the greatness of this headphone.

Uses their propriety A2D2 connections for the headphone cable. If you ever need a replacement, they charge a fortune for a replacement cable.

Beautiful to look at, light and comfortable. The Sound is Very v-shaped, with the mids scooped out. I hear that they are good for EDM and hip-hop. If vocals are your thing, you might want to keep looking.

The sound signature is bright and sparkly. Decent bass nothing that will of course blow you out of the water. These are nice portable headphones that really pushes the envelope of what you can expect in the portable category. I really like them. The design is beautiful. The wood is what really stands out and I can see that these headphones are getting into a fashion statement than just performance/audio.Headphones are comfortable and lightweight. The diamond/carbon coated drivers are extremely similar to my AP-2000TI which is a 1200$ headphone! In fact since these came months after the release of the ap-2000Ti I'd say its even better than the AP-2000TI! Its much more lighter and comfortable for long term despite them both being portable headphones. I wish the pricing was maybe cheaper into the 500$ category but you are really paying for that imported Japanese quality like a Toyota tacoma or something.The sound signature albeit great and bright is much less fatiguing comparatively for long term for sure. It really brings forward that female anime protagonist weab noise that most other headphones don't handle that well. Which means that for other headphones would be even more fatiguing. This is exceptional in that regard. Im talking being on the edge of having sibalance. Its amazing and perfectly tuned for portable use. I'd even argue that in many songs and many cases that these headphones are better than my HD-58X jubilees, and DT 880s (600 ohm).

Los mejores audífonos que he tenido. Los graves son profundos y a mi parecer son excelentes para cualquier tipo de género. Los medios exquisitos, cálidos, es el fuerte de estos audífonos. Los agudos ligeramente brillantes. En general tienen un balance muy bueno. Los recomiendo para escuchar música desde cualquier dispositivo pero sí o sí con un Dac.

ちょっと前にモニターヘッドホンのATH-M50xBT2を購入。モニターヘッドホンなので、当然、音を変えるような仕組みなど導入されるわけもなく、バランス接続も未対応…当然ですよね。すっかり意気消沈してましたが、ATH-M50xBT2の音には惚れ込んでしまったので愛用しています。ワイヤレス対応という利便性もありますから…といって、NW-WM1AM2をヘッドホンでバランス接続で聴きたいという欲求は収まらず、今回も悩みに悩んで、ATH-WP900を思い切って購入。まず、箱を見てデカっ、中を開けて高級品ってな感想を持ちつつ、本体と付属バランスケーブルを取り出し、取り付け…み、見えません…老いた眼には文字が小さすぎます…という訳で、老眼鏡をかけて取り付けて装着。軽い…軽すぎる…側圧…ほぼ無いに等しいのではってくらい私の頭には馴染みました。もともとATH-M50xBT2という側圧のあるヘッドホンを使用していたので、余計にそう思ったのかもしれませんが、ATH-M50xBT2はモニターヘッドホンという性質上、シッカリと着ける必要があるので多少キツ目になってると思います。※ ATH-M50xBT2の側圧が特にキツイわけではありませんのでご注意を。私は着けたまま寝てしまうことも度々あります。個人差はあると思いますので、ご容赦を…。さて肝心な音質ですが、低域から高域までクリアで元気に鳴るヘッドホンです。リスニング用にチューニングされていますが、細部まで聞き取ることが可能で、変に何かを誇張していることもなく、音質に癖はありません。素直に、どんな楽曲も元気よく鳴らしてくれます。このへんはモニターヘッドホンのATH-M50xBT2と違うところです。ATH-M50xBT2は、音源を忠実に再現します。そうでなければ、作成作業などできませんので、当然です。ATH-M50xBT2は、その本来の目的故にCD音源とハイオク音源との違いがハッキリ分かります。分解能も流石で、いくつもの音を重ねて作成したんだなぁーとシミジミと思いながら音楽にドップリと浸かる感じです。一方、本機のATH-WP900は、分解能もあり、CD音源だろうとハイオク音源だろうと、その楽曲の意図を崩さずクリアで元気に聞かせてくれるヘッドホンです。たぶん、こういう感想を抱いたのは、ATH-M50xBT2の音を聴いたからでしょう。このヘッドホンは、木製ハウジングと53ｍｍのドライバーが楽曲の雰囲気を壊すことなく、キラキラした音質で聴かせてくれると思います。ATH-M50xBT2は、楽曲の作り手の意思を感じることができ、楽しく聴かせてくれるヘッドホンです。どちらも、私にとっては最高のヘッドホンです。この２つのヘッドホンで大満足です。なにか変なレビューになってしまいましたが、すみません。

発売開始からほぼ4年。最近価格が急に下がってきたので、ひょっとしたら後継機の発売があるのかも？と思いましたが、新型が発売になるとすれば値上げは必至なので、お買い得価格の今のうちに購入しました。今まではFIIO M15にK712PROかHA-SW02(4.4mmリケーブル済)を組み合わせて聴いていましたが、ワイドレンジ感はあるものの、少し聴き疲れする音質に感じたので、まずはDAPをHiby R8に変更。K712PROのサウンドが聴きやすくなったので、さらにヘッドホンも変えてみたらどうだろうと、少しお値段の高い本機を購入しました。4.4mmバランスケーブルが標準で付いているのもポイントでした。　エージング中ではありますが、購入してすぐ音楽を聴いてみて「これまでと全然違う」と確信。低音が弾むように出てきて、しかも押しつけがましくない感じ。ひとことで言うと「音楽にノレる」感じ。コンパクトな密閉型ながら、音場の広がりもそれなりにあり、中高音もきれいに出ます。　バランス接続のせいか、左右の分離も良く、それなりの大音量で再生しても聞き疲れしにくい。K712PROだとクラシックを聴くのが好きですが、ATH-WP900の場合はジャズ、ボサノバなどを聴くのがお気に入りです。低音のリズムが心地良くて体も動いてきます。こういう経験はいろいろヘッドホンを持っていますが初めて。低音が変なかたまりになって押し寄せてくる嫌な体験は今まで何度かしていますが、心地良い体験は初めてですね。低音嫌いだった自分が変わったような気がします。音色は全体的に明るめで軽め。解像度もそれなりにあると思いますが、リスニング用ヘッドホンなので分析的に聴くタイプではありません。全体的に軽量なので、旅行先に持って行くヘッドホンとしてもいいと思います。ただ、キャリングケースはセミハードタイプにしてほしかったところです。ソフトタイプはカバンの中で他の荷物に押される可能性もあるので。デザインですが、定価10万円近いヘッドホンとしてはもう少し頑張ってほしい。安っぽくないようにしているとは思いますが、高級感も感じにくい。せっかくのウッドハウジングですが、表面のテカテカ具合が強すぎて逆に樹脂っぽく見えてしまいます。それから、A2DCのリケーブル、もう少し種類が増えるといいですね。現状では3.5mmプラグと比べるとまだまだ少ないです。それと、LRの区別がしにくいのも困ったもの。デザイン優先なのかL、Rの刻印が字が小さくて見にくい。ヘッドホン本体のLRの区別もわかりづらいです。全体としてはとても気に入っています。もうこれ以上を望むと、15万円オーバーのヘッドホンが必要になりそうです。ヘッドホン沼の深みにどんどんはまっている感じですね(笑)

Pros: well-made headphones that are both solid and comfortable to wear.I'm not so sure if "it's the wood that makes it good" or if the thin piece of maple is merely for cosmesis. However, the sound reveals good musical detail and tonal balance.Nice mid-bass weight but a bit thin on the sub-bass. Beware that these need a high-quality DAC. I was fairly disappointed using a rather cheap one I had on-hand, but with upgrade to the new Astell & Kern, I felt that I was finally able to unlock the quality of the headphones.Cons: Although I am consistently engaged, at times I feel the emotional gap acutely when comparing the experience of listening to some of my favorite tracks on these to when I hear the same pieces through my Tannoys. I thought these would be a huge leap forward compared to listening with my old Bose QC35, but I would say these are only incrementally more impactful. I probably expected too much.More important, this is my first A-T headphone purchase, and I didn't appreciate how atypical the cable connections are and how hard it is to find alternatives to the OEM version. Had I known my upgrade options were so limited, I may have turned to another manufacturer.
