Sony MDR-EX800ST(Japan Import)

They sound absolutely fantastic - I could not begin to recommend these enough. Before buying these, I had assumed that IEMs in general would necessarily have worse bass than over-the-ear headphones, owing to their smaller drivers. This view turns out to be completely wrong: IEMs have smaller drivers, but operate in not as large a volume of air, and it is the ratio that matters. The bass of the Sonys both goes just as low and sounds cleaner than my JVC SZ-2000s - that, folks, is quite the accomplishment. Sound stage / separation is better than the SZ-2000s, and better than a $200 pair of old Audio-Technicas that I also have. Most importantly: these sound fantastic and well-balanced *WITHOUT* any EQ, which makes them usable on-the-go. Many other headphones don't really sound their best unless you plug them into a DSP, which in practice makes them hard to use on-the-go. Sound isolation is good enough for city transit. Medium tips felt best for me - they come with three sizes. The headphones are designed for the cable to wrap around the ear, but the stock cable is so stiff that I couldn't get it to stay in the right place. I ended up getting rid of it entirely, buying an MMCX adapter, and wearing these in an earbud manner with cable pointing down rather than around-the-ear. This has worked out well for me - more comfortable and no problems with falling out. Pros: * Amazing sound. Solid bass with a well-balanced overall aesthetic. * Very good price for what you get. I've paid double for worse headphones before. Caveats: * Very plain packaging - ordinary white box with everything in Japanese, not even a picture. Looks suspicious, but very clear from the sound that these are the real deal. * Japan import - you're implicitly paying for tariffs and import fees, which would not be necessary if Sony sold these as a US product. * Warranty requires dealing with Sony Japan - no personal experience with this. * Stock cable is absolute trash. Get rid of it immediately and buy an MMCX adapter.

This is the latest of my purchases of Dynamic Driver iem’s , and although the self-proclaimed audiophiles and professional reviewers vehemently disagree with others in this subset about burn in, for this product I have experienced an obvious improvement in the upper midrange and lower treble regions after around 45 hours. These have been around for years, and some “experts” claim they need more than 100 hours to start sounding good. CA Honeydew and IKKO OH10 seemed to improve somewhat, DENON ah-c820 showed no change, but these are much better after burn in. The first day I was ready to return them, but I changed my mind after giving them a few days. The hack of covering the vent and putting a pin hole in the tape increases the bass profoundly. Then I replaced the silicone tips with Comply foams and these have moved up in my rotation. The sub bass rumble is unmatched-I’m waiting for a chance to get the FatFreq on eBay. If you’re not a basshead, but you’re treble sensitive, just make the hole in the tape over the vent larger. There’s also foam in the sound tubes that diminishes the upper treble that can be removed, but I don’t need that for my preferences. So….these are easily adjustable to your needs. I enjoy the midrange and the wide soundstage as is, but if you’re coming from iem’s with a narrow soundstage, your brain will have to adjust-it was initially distracting (although I am easily distracted). I will update after 55 additional hours. I do equalize and amplify them, so your results may be different. Update: I replaced the Comply foams with the t200 in large size to better stabilize and for a better seal. After 100 hours I still had issues with the upper treble region when there was a lot of information that seemed to overwhelm the huge Dynamic Drivers. I purchased a 2.5mm balanced cable ($38 on eBay), and that improved the treble region tremendously. FOR MY MUSIC. I listen to dark, bassy music, guitar centered blues and jazz fusion, so these are great for me. The bass is amazing, midrange impressive, and the treble is okay. Your genres may not give you the same experience. Keyboard, female vocals and percussion are all exceptional. Details and soundstage are fantastic for the $220ish I have invested. But-for someone with different musical tastes-$135 for the DENON ah-c820 on eBay and $110 for the Shanling ua3 DAC amp will give you most of thump, impressive mids and treble.

XBAシリーズをこよなく愛する者ですが、Z5の販売終了に間に合わず、やむおえず中古品購入となってしまった経験から、欲しいと思った今、購入に踏み切りました。 BA＋ダイナミックドライバー構成のXBAに比べると、音の派手さはなく、最初は物足りなさを感じました。ですが、日々、通勤で使用している内に、慣れというか良さに目覚めたというか他の方のレビューにもある様に、ナチュラルな再生域、音域が心地よく感じる様になりました。 まだ価格改定前の在庫を所有しているショップさんがありますので、安く新品を購入する最後のチャンスだと思います。 自分はDAPの都合で購入後、すぐにMMCXアダプタｰ＋コンプライTRZｰ200＋onso iect_03_bl4m 4.4mmに換装して使用中です。 付属ケーブル使用との使用感や試聴感に若干の違いがあるかもしれません。 ご参考までに‥

excellent

Llevo más de un año con estos audífonos y lo único que puedo decir es que no te vas a arrepentir: el sonido es simplemente perfecto, aunque sí recomiendo hacerles un poco de burn-in. Con ellos es muy fácil notar cuándo una canción está bien producida, porque suena increíble; las demás solo se sienten simples en comparación. Son muy buenos si te gusta ecualizar la musica, realmente cambia mucho el sonido.

great headphones with nice strong bass. Sad that i lost it using only a month.

I have purchased a number of high quality Sony IEM and these are very good . Clear quality sound without too much base emphasis allowing vocals to shine and they are comfortable
