The ES100 clearly has more features and customization options than the BTR3 which will appeal to certain power users. At the same time, some will feel more comfortable with the more straightforward operation of the BTR3.

ES100 MK2 Bluetooth Receiver (+HE100 Earphones for free!)

So many things that make little audible difference are tweakable on the ES100. So why not something that can easily be heard, like a way to select the crossfeed implementation? ES100 hardens by a chemical reaction. It is essential that the mixing instructions are strictly adhered to: All in all, the ES100 MK2 is pretty versatile, fairly potent for driving headphones, and has a low noise floor, being perfect for IEMs too. This makes the ES100 only the second Bluetooth device I’ve heard that’s completely silent. (I can’t hear any hiss from my Airpods either.) The physical volume up/down buttons on the ES100 control the analog volume, so it behaves differently in Apple devices than other Bluetooth headphones. In iOS, a Bluetooth device’s physical volume controls normally control the iPhone’s or iPad’s system volume. Not so with the ES100, and that’s a good thing because it gives you fine control: +/- 0.5 dB steps, unlike the very course adjustment in iOS. Earstudio ES 100 MK II vs Qudelix 5K (90 USD vs 80 USD) – It feels a bit like 5K from Qudelix was made as a child of ES100MK2, but made by a different designer. The two bluetooth receivers have a similar build, similar overall build quality, similar concept, but different design and aesthetics. The overall audio performance is comparable, but 5K is a bit more neutral, manages to squeeze a bit more detail from music, but has much less dynamic, less driving power, and less overall realism to it, where ES100Mk2 is more punchy and warmer in the bass and mids.

I will describe overall sound processing of dual AK Dac as extremely well layered, smoothly detailed and wide sounding with lot of extra deepnest to it. It have the capacity of extraction more sound info and give extra excitment to the music you think you know, like if a veil was pulled off wich permit you to perceive whole audio range of your favorite music without it feel artificial or too analytical. As well, I feel it give extra energy and dynamic to the sound, especially mid bass that feel more controled and way less boomy than lot of phone audio, like my G6 or even more my Ipod touch. In some way, if you do not listen to wide music style, perhaps the audio revolution you get will be minimal, but with great quality recording it is an evidence that this bluetooth receiver can transform your music into audiophile experience mustly seen in good quality DAP. With 192 note polyphony, the Kawai ES100 beats other digital pianos that are in the same price range. This means that the keyboard can produce 192 polyphony notes without increasing the price of the piano, while other pianos in the same price range may only be able to produce 128. Sound technology This device is not about the look at all, it have a low profile approach in a very small body. Its all plastic with the exception of metal clip. I would have love at least to have metal headphone output of better quality, but it do not change anything for the sound, perhaps the durability tough. So yeah, perhaps too much plastic.To find Ready Mixed colours, search "ready mixed" or select the Ready Mixed 'colour chart'. To see Tinted colours select a colour chart such as RAL, BS, NCS, etc. or search for a colour/hue to see available or related options. The 10-band EQ works best with headphones that already have a smooth response, like the two IEMs above, or when there is a broad peak that lands close to one of the equalizer’s ten center frequencies. It's easy, for example, to give an Etymotic a little more bass. The EQ is more limited when you want to make the adjustment at a frequency that’s far from one of the graphic equalizer’s ten octave-spaced bands. For example, the Bose SoundTrue Ultra has a half-wavelength resonance that’s always at the same frequency because it has the same, repeatable, shallow insertion depth (if you could call it that). On my ears, it’s near 5.5 kHz—far from the ES100 EQ’s 4k or 8k bands. What’s strange is that I’m getting the same or better results when I leave it on normal mode. It looks like high current mode is on regardless of the setting in the app.

Colours are sold in the nearest tin size but actual paint volume per tin may vary up to 10% depending on colour A practical coverage of approximately 20 m² – 24 m² per 10 kg unit is expected, dependent on application and porosity of the concrete subfloor. I bought this to increase the convenience level of my Ety ER4XR. I have previously used (and abused) extensively the Samsung HS3000. What I wanted for my Eties was something like the HS3000, but with more power. The device I received exceeded all expectations. The EQ supplements the nearly-missing EQ functionality of the iPhone's Music app nicely. The interface is intuitive and easy to use. Whether you’re a student or you’re looking for a new digital piano for your musical hobby, the Kawai ES100 is a great choice. It will not only help you learn with the built-in lessons, but it will help you create something magical in the comfort of your own home and at an affordable cost. Key featuresEven when nearing maximum volume you can barely hear any distortion, which is again a positive direct result of Radsone’s design choices. Final Thoughts The Earstudio app for Android or iOS gives the ES100 a TON of extra versatility and is an absolute must if you want to get the most out of it. Earstudio is a new comer in audio world and deserve alot of respect, one thing sure, I will follow the evolution of this extremely promising company in the futur. Now that I know bluetooth technology can sound this good, I became interested in something I always been sceptical about and humbly admit BT codec transmission will must certainly achieve high end sound transmission in a very near futur. The hype is far from being finish with the Radsone ES100, and it will surely still be used in years to come. Remove all surface dust, etc., by industrial vacuum cleaning. Machine scarifying or shot blasting will be necessary for removal of incompatible curing agents, admixtures or other stubborn surface contamination. Shot blasting is also recommended on lightly polished surfaces.
