EarStudio New: HE100, High-Resolution Earphones, 3.5mm in-Ear Headphones, Distinctive Clear Sound, Single Powerful Hi-Res Dynamic Driver, Comfort Fit, in-line Microphone

This is an excellent Bluetooth DAC/amp. I use mine to connect via Bluetooth to my phone, I stream music from my phone to the device and I listen using whatever wired earphones I feel like using. A DAC converts the digital signal to analogue sound and the amplifier makes it louder. Devices like this effectively turn any wired headphone or IEM into a wireless one only you get to choose the headphones you want to use. Many people don't want to be restricted to those earbuds and headphones that manufacturers turn into Bluetooth models. Devices like this with decent earphones sound better than wireless buds and headphones. With a wireless headphone once the battery inevitably degrades or the electronics fail after a few years you have a useless headphone that the manufacturer won't service. A Bluetooth DAC/amp makes way more sense. Wear it on your upper body using the clip or a lanyard and you then have just a few inches of cable running to your headphone. Your hands are free, no wire running to your phone and you have great sound. I'm pretty enthusiastic about these gadgets and wonder why I don't see more people using them. Bluetooth is not what it used to be, this device can use LDAC which is a codec that can transfer data at 990kbps rather than the 330kbps that was once the norm. It is almost lossless. I doubt many people couid identify a track streamed over LDAC bluetooth from a track played using a wired dongle. It can be used as a USB dongle DAC but I don't use it like that. These devices are intended for use in your personal space, not for streaming over long distances. Range varies depending on structures but about 10 metres is about the most you should expect. As I have my phone on me as well as the device the range isn't important to me. Some people find that if they put these devices in a trouser pocket their body blocks the signal. I've never experienced this but I always wear mine on my upper body. This device has buttons that can be easily activated so it is best to keep it out of pockets that have other stuff in them. The ES100 is known for it's amazing app. You can get into tweaking the EQ and all kinds of settings, it is very comprehensive and some of it requires a little expertise. You don't have to get into that though. The app is set up by default to give you clear access to the core features for simple management. You can access the other stuff easily but most of what you need is in one very simple page. I particularly like the feature that estimates the sound volume in dB. Good to keep an eye on that. This has so many features that I can't get into describing them all. The ES100 sounds fantastic, I use other devices of it's type that cost more and it sounds just as great. The one thing that really impressed me is the battery life. I have two other devices like this with similar spec and features from another manufacturer, the ES100 runtime using LDAC is longer than the combined runtime of those devices at around 15 hours. It is such a tiny gadget too, I've seen it many times on video and in photos but when I got it it looked about half the size I expected. This gadget has been around a few years now and is still one of the best, so good I can overlook the micro usb port. All of these devices are around the same price and they all do pretty much the same thing. There are small differences, this one can't do 24/192, you would need the Fiio BTR5 for that, the BTR5 has much shorter runtime, a far more basic app but is still a great gadget and can power far more demanding headphones. If you're not bothered about 24 bit192khz and many people including audiophiles aren't, this device is a great choice. The ES100 has a lot of charm to it, it was designed by a small company and they put a lot of work into making something far better than you should reasonably expect.

I tried a few DACs, including the ifi Hipflask and FIIO Q5S - costing 3 times the ES100 Mk2, and yet the ES sounds so much better than the others. My headphones are Meze 99 Classics - another inredible buy. It comes in a tiny weeny little box, and my first impression was 'i've been conned, this is not a £100 product' Then when you take out the device, it is ridiculously light, so again - I thought 'this is cheap chinese rubbish'. It was very easy to set-up, but I didn't have an OTG cable for my iphones - which is hard to find anyway because it's a Micro USB port (I was tempted to drop 1 star for this because it's so frustrating to work with. Ok, so I guess it all sounds pretty negative so far? But then, the sound. This is where everything changed. All all the aforementioned niggles just dissapear, because the sound is simply stunning - too good for such a tiny product. Like watching watching the X-Factor when you judge someone on their looks only to be blown away by their sheer talent. It's powerful - easily drives by fll-size Meze 99s. It's clear, strong and yet smooth - but not too smooth to sound veiled - it's just not as 'digital' as I was expecting. Plus points: - Music is simply stunning (for the size and price) - Bluetooth Aptx sounds better than wired - on the above DACs that cost 3x the price - It's so light you will want to keep it clipped on you wherever you go - It's 100% reliable bluetooth connection - It comes with a great IOS app too Negatives: - micro USB connection (I almost dropped a star for this) making it USBC would make all the difference - Feels so cheap Overall: Crazy value for money, comebined with wonderful sound and ultimately portability. One of my best buys on Amazon

Das wichtigste zuerst. Der Sound ist top. Ich konnte mit einem HifiMan Edition XS keinen Unterschied in der Klangqualität zwischen direkten USB-C Anschluss über einen Standard DAC sowie ebenfalls Earstudio 100 im Vergleich mit Bluetooth Übertragung durch Earstudio von einem IpadAir 4 feststellen. Einziger Unterschied ist die maximal erreichbare Lautstärke. Die ist mit dem EarStudio ausreichend hoch. Beim direkten Anschluss über einen einfachen USB-DAC ist die maximale Lautstärke mit dem HifiMan doch etwas eingeschränkt, was auch zu vermindertem Druck im Tieftonbereich führt. Darüber hinaus ist die App sehr gurt gemacht und intutiv zu bedienen. Der dort einstellbare Equalizer ist brauchbar und lässt sich auf gut die eigenen Bedürfnisse einstellen. Die Akkulaufzeit des Geräts ist gut, ich schaffe damit mehr als 10 Stunden Bluetooth Hörzeit. Schön ist, dass das Gerät sowohl über Bluetooth als auch über USB an das Mobile Device gekoppelt werden kann (und dann auch mit Strom versorgt wird). Ich nutze es nur noch per Bluetooth, da ich keinen Unterschied wahrnehme (siehe oben). Über die Haltbarkeit kann ich nach 2 Wochen Einsatz noch nicht so viel sagen aber bisher macht sich das Gerät gut und der Clip zum Befestigen an der Kleidung, etc. ist gut. Die Bedienung über die Tasten am Gerät ist ok. Man muss sich die Lage und Funktion der Tasten am besten einprägen, sonst ist es etwas hakelig. Der Preis ist für dieses Gerät angemessen, insbesondere, da der Sound gut ist sowie die App und die Bluetoothkopplung gut funktionieren. Läuft bei mir mit iPhone 12 (Bluetooth) und IpadAir 4 (Bluetooth + USB).

Mi è piaciuto immensamente, da non credere..! E' vero, è di plastica, piccino piccino, costa sui cento euro, ma la resa sonora che restituisce non ha eguali, nemmeno con cell ultima generazione...Ha potenza da vendere, sui cell e su tablet, te la sogni, durata batteria minimo minimo sette otto ore (dipende in gran parte dal volume) ha il plus di avere due uscite cuffia, tradizionale da 3,5 e bilanciata da 2,5 per chi ha cuffie idonee, o ha cuffie o IEM con cavo staccabile, per ottenere un suono di qualità superiore! (mi sto attrezzando) Ha i soliti comandi, anche se tasti piccoli, commisurati alle dimensioni del corpo "macchina"...power, volume, salta traccia, e un mic dalle prestazioni quasi pro. Mic che si può utilizzare, volendo, per non isolarsi completamente dall'esterno; modalità surviver in città! E non è finita qui, la vera chicca è la sua app, completissima, per qualsiasi tipo di regolazione, dal bilanciamento dei due canali, al tipo di uso che se ne vuole fare; ampli, o solo pre (io lo uso così, avendo due Cmoy , non quelli delle pasticche americane, evoluti e modificati, con doppio AD 797N single, montati su browndog, e OPA 823), o avere il doppio di potenza per cuffie "difficili", ma non si spaventa nemmeno con le mie "880" da 600 ohm! E poi equalizzatore, BT, quasi tutti, dac doppio per prestazioni superiori ecc. ecc. Tutto un mondo da scoprire, ci vorrebbero ore per descrivere tutte le opzioni..! E' leggerissimo (e vorrei vedere) ha una clip per agganciarla a...dove volete! Si carica velocemente, con la possibilità di non caricarlo al 100%, secondo il produttore può allungare la vita utile della batteria, e via dicendo. Insomma, una vera scoperta, piacevole. Ha scardinato l'opinione comune che il BT è inferiore al cavo, sarà, ma in questo caso la differenza è davvero inudibile! E poi suona, suona veramente...la musica scorre via facilmente, è trasparente, non si intuiscono i dettagli, si sentono, eccome , ha una estensione di frequenza eccellente, bassi stretti, potenti e profondi, gli alti sono dolci, ma dettagliati, i medi presenti, lucidi, dulcis in fundo, presenta un palcoscenico ampio e profondo quanto basta, ma anche di più! insomma una vera ...goduria! Chi vuole provarlo e se lo può permettere, non resterà deluso...Attenzione, non è un lettore, per questo c'è altro, ma abbinatelo con uno di buona qualità, e ne sentirete delle belle! Consigliato? Dopo tutta questa "tiritera", certo che si. Amazon, grazie, anche se viene spedito dalla divisione europea Radsone, che è il produttore. Buon ascolto.

Enjoy your headphones to their full glory with this amazing DAC. Near perfection for wireless high-end HiFi. Powerful amplifier let's you wireless enjoy your studio headphones anywhere, all day. Bought this DAC especially for testing various modified Koss KSC75's and Koss HP30's that require that extra dB output this EarStudio hides under the hood. Priced at around $100, this gem turns the $20 Koss KSC75 into the league of audiophile headphones of $ 500 plus. But no USB C, so charging and operating as USB DAC is like Russian Roulette. ( As goes with mobile equipment with USB connection ) . After three weeks of daily usage, the USB connector was moved a few millimeters and the case surrounding the USB connector shows damage and reveals the white plastic of the case. The case is painted in aluminium look with very thick layer of paint. This makes the icons on the buttons hard to see and caused the track selection button to stay pressed inwards. I returned mine and wait for new one, falling back to my second choice, the comparable FIIO BTR3K that lacks the extra stamina and output power of the EarStudio but is build around the same chipsets in a very durable casing. For my new EarStudio i will only use a decent USB cable (from my Jabra Evolve 40 headset) and have to handle it with some extra care when on the move as I am hooked to the vast customization options that give me the most deep felt music experience outside a studio.

Great value item with good sound quality. Companion app has a lot of useful features and allows for high degree of customization.

These sound very good. I have them with the ear studio HS100 DAC which is a perfect combo. The bass is rich and perfect high end. I play podcasts and EDM with them to make an old man very happy. me being the old man of course. This headphone is really for the audiophile but dont let me stop you buying it as its worth every penny for the price. I havent tried the sound for the mic as I use the HS100 which has amazing mic performance.
