Just got my Earstudio's today. Doing this comparison on a pair of Shure SE846.
Using the regular 3.5mm jack, they sound very similar to the Get's, in that they both sound very good for unbalanced output. The Get has abit of boosted bass, while the Earstudio's have abit boosted high's. The AK XB10 sound the most balanced to my ears, but please keep in mind, with the exception of the Get's (whose bass-boost is absolutely noticeable from the get-go), these emphases are not huge, and should not dictate which one of these you should go for.
But just like the Get's and the unbalanced XB10 output, once you compare it to the balanced output on the earstudios and XB10's, the soundstage definitely opens up, instrument separation is increased, and possibly as a consequence of this, clarity appears to be improved abit.
Comparing 2.5mm earstudio to 2.5mm XB10, the XB10 still has a wider soundstage, and I can pick out the microdetails just better, but since the high's aren't as boosted as the earstudio's, some may think the earstudio's have better clarity.
The earstudio's give you far more technical control, like how fast the decay is, jitter filtering, etc. And the ability for firmware updates, such as the recent one that allows us to change the volume on system sounds (i.e. sound of it when it powers on and powers off), is absolutely fantastic. Before I updated the firmware, the sound of it turning on was genuinely deafening, it was awful. Also, the earstudio's have an option for EQ as well, so you can customize this to give you the exact sound signature you're looking for. Very nice for people who like that.
This level of customization is rarely seen in these bluetooth receivers, so it's very nice.
Also the noise floor (hiss) is barely audible, and most won't notice it at all even with high sensitivity IEMs like the SE846 and Noble K10, so that's a plus. It's definitely the lowest of the 3.
There's merits for all 3:
AK XB10 subjectively sound the best to me, and despite costing more than the rest, I am happy I purchased them and would do it again if an IEM warranted it (currently using it between SE846 and Noble K10, both balanced). Really wish the build was nicer though... Feels crazy cheap...
The Earstudio's are a far cheaper, excellent alternative to the AK XB10, provided you can use them balanced. They sound great, level of customization is great, I haven't used them enough to test battery life but they claim it's longer, and really, even if it's the same as the rest, this still wins by many standards (provided you can use balanced).
The Get is excellent for unbalanced sources with higher impedances than typical IEMs, as many of us have found the noise floor on the Get's to be unbearable on high sensitivity IEMs. The Get really sounds very similar to the other 2 if you're using unbalanced, which many people are, so there's not many benefits for going for the rest in that case, but that noise floor with high-sensitivity IEMs...
P.S. Bonus round, I also received the Aqua+ from kickstarter.
Since it costs 2x as much as the earstudio's and the Get's, with only an unbalanced output, it's by far the least worth it of all 4, but it's build is the nicest, and comes with a leather case. BUT, the leather case adds some bulk, and you have to take it off every time you want to charge the thing....... And it charges wirelessly via Qi charging, so having to litter your home or workplace with qi chargers, or bringing the (very small) qi charging pad with you is definitely a con...
Sound wise, they sound similar to all 3 unbalanced. They have a button on it that you push, which supposedly upsamples all music to 32bits, which is ridiculous because you can't add detail that wasn't there to begin with. Instead, what you will notice is a VERY intense DSP filter being applied. Have to admit, it does widen the soundstage abit, but it boosts the highs and low frequencies so much, and pushes the mids back, as to try to give you "greater clarity" and "better bass", while "widening" the soundstage simply by pushing the mids back. It makes the music more "fun" for most people, but the fact that they try to pass off upsampling as this magical thing that will make your 128kbps MP3 sound like lossless feels insulting.
In any case, don't go for this one. It doesn't sound bad by any means, but I feel they justify the increased cost because of that stupid button.
When you can get the Get or the earstudio's for half as much, or even the AK XB10 for slightly more, they beat this any day of the week. It's just too overpriced when you compare it to the competition. Now if the get's and earstudio's weren't half the price, then we'd be having a different conversation...
Oh and a little background note, before I tried balanced, I genuinely believed that going balanced would do nothing more than just give you more power and a slightly cleaner sound due to the way that it's wired. Definitely depends on what you're hooking it up to, but in the case of the earstudio's and the XB10's, there's definitely an audible difference.

So I just got my 2x Bluewave Get's today. I also have the Astell&Kern XB10's as well.
And if I didn't hear the XB10, I would've thought the bluewave's were top notch. They're still one of the best bluetooth receiver's out there, and for the price, they're a steal compared to the XB10, but the XB10 is better if you're using balanced, and I wouldn't hesitate getting the XB10's again over these if I'm using these with higher end IEMs.

Design wise, the bluewave's are 1000x better than the XB10's. The XB10's feel like a toy; the plastic is thin and doesn't inspire confidence that if you drop it, that it wouldn't crack. The get's are much more solid and built better.
The buttons are in a better and more logical place as well on the get's.

The noise floor on the get's is absolutely monstrous, especially with very sensitive IEMs like my SE846 and my Noble K10's... It actually overpowers alot of the music unless I turn them up to deafening volumes.
The noise floor on the XB10's is lower when unbalanced. With balanced, it's not silent, but it is significantly lower than that. So if we say the Get's noise floor is 100%, then the unbalanced XB10 is 60%, and balanced XB10 is 30%.
So this already is a HUGE advantage if you're using sensitive headphones.

In terms of music reproduction, the AMP on the XB10's is definitely cleaner. Bass is tighter, vocals sound abit more lush, highs are extremely pleasing as well, none of that compression that you typically hear in the high frequencies from other lower end bluetooth devices (the get's don't experience this either, so that's good).
Compared to the XB10, there's definitely abit more sub-bass on the get's, so the low-frequency roll off that plagues bluetooth devices is definitely well done on the get's. But bass sounds abit more bloated, highs aren't as clean. Mids sound good, but slightly less forward. But when using this with sensitive IEMs, the hiss really affects the vocals and makes everything sound grainy...
I would definitely say the get's don't sound as open in terms of soundstage, but that may be due to the less forward mids when compared to the XB10's balanced. When unbalanced, they actually sound similar; the XB10 loses some of its sparkle, bass gets more bloated and mids get pushed back abit, and at this point the get sounds close, with the exception of the hiss... Like it really masks some of the vocals at regular listening volumes, I can't tolerate it on my sensitive IEMs.

The get's are very good, and honestly if I didn't do a side by side, I wouldn't be so harsh on them.
I'm glad I have them in my collection especially for the less sensitive stuff, and for their price, you can't find better. And when you only have unbalanced headphones, they sound just as good as the XB10's.
But if you're not concerned with the price and you have 2.5mm TRRS termination headphones, then the XB10 is the one to go for.

Edit: I also have 2 of the Noble BTS. They're not even worth comparing with either of these. There's intense bass roll off on these, connection isn't great, high's are very shrill, mids sound very hollow with no weight to them (probably stems to the bass roll off). Sound stage is decent, though, AND these have like, no hiss, so there's that. These may have been a good solution back when they first came out, but with the XB10 and now the get's, the noble's are pretty much obsolete, especially at MSRP of $100.

I do love the GET and I use it daily in my musical performances. I will never go back to the old wired headphone setup again.
IN FACT I WONDER HOW I GOT ALONG WITHOUT A GET IN MY ARSENAL OF SONIC TOOLS!

... и мои субъективные впечатления о сравнении XB10 С ES100, пока не забыл:
XB10 играет более драйвово, сцена шире. Звучание с акцентом на бас и верхнюю середину.
ES100 при всех наворотах в описании подает звук более сглажено, спокойно... иногда может показаться, что присутствует нехватка вч (хочется добавить искорки, особенно на темных наушниках). Бас отличный, но менее напористый, чем в XB10.
Тем не менее, оставил себе ES100 из-за удобства использования: управление и настройка через приложение на смарте перевешивает даже то, что звучание XB10 мне понравилось больше.
По автономности: не заметил я особой разницы между XB10 и ES100, - 6 часов работают оба (использую по 2-3 часа в сутки, заряжаю на третий день).
