Great to see that ASR's reviews of the Zorloo Ztella, Earstudio HUD1000 & Xduoo Link are out. Only real disappointment was the Xduoo Link, but the other two options were decent. Have just added DD T35B to the list, an interesting option that's probably only the size of a jelly bean.

DD TC35B
https://www.aliexpress.com/item/4000701034717.html
ALC5686
THD+N: <-92dB
DNR: >110dB
SNR: >120dB
Output Power: 30mW @32Ω
6g weight and 18.8 x 11.2 x 10.2 mm

After my experience of the Zorloo Ztella only lasting a week or two of use in my pocket, this extremely compact, simple, cable-free design looks very appealing. I would love to see an ASR review of this innovative product.

Thank you, I've added the MBquart DAC. The Yulin S2 is already in the list as Yunlumei S2.

After my experience of the Zorloo Ztella only lasting a week or two of use in my pocket, this extremely compact, simple, cable-free design looks very appealing. I would love to see an ASR review of this innovative product.

My dd TC35B just came in the mail. Its sound quality is a good step up from the headphone jacks on my Galaxy S7 and Lenovo Yoga 920. Importantly for using it with my portable speaker outdoors, its output is quite a bit stronger than my Galaxy S7 for a better signal to noise ratio. If I remember correctly, the Zorloo Ztella sounded a bit better, but I can't directly compare anymore because the Ztella broke so that's a moot point anyway. The dd TC35B seems well constructed with the stainless steel casing. Even if its quality isn't the best of the best, as far as I can tell dd is the only company that has figured out how to make one of these dongles in a design that is both durable and truly portable (as in, I can conveniently use it in my pocket on a bus). I'd love to see an ASR review of the dd TC35B.

That is great to hear that you are enjoying your DD TC35B. What do you mean by "its quality isn't the best of the best" by the way, are you referring to its build?

Hi,

I'm looking for a dongle with volume control to plug it to my Xduoo X10TII.
I mean real volume. As an example the Xduoo Link is only controling the volume of smartphones...
Would you have any idea ?

Musiland MU3X
https://detail.tmall.com/item.htm?id=626413576267
http://www.musiland.com.cn/index.php?m=Product&a=show&id=35

dual CS43131M, 4.4mm and 3.5mm out, 4vrms max (allegedly) on balanced out, filter switching with display, hw volume, usb-c in. pretty much tick all the boxes if it's really as good as advertised, also pretty expensive but I've had better luck with musiland products on compatibility with windows and android (tempotec sonata hd pro won't play sound outside usb audio player pro on android, weird sound glitch above 44khz sample rate on windows) so I'm hoping this will finally be the no frill solution.

Was also interested with yinlumei above, but found this review by a verified owner:
Loud Noise Floor This amp has a very loud noise floor, a high pitched buzz can be heard with all iem's I have tested. The buzz is louder with more sensitive iem's making it unusable with the majority of my gear. The best luck I've had with it is with insensitive over-ear headphones, where the buzzing is nearly inaudible. The sound itself is very good. It is punchy, detailed, and airy. It is also very good looking and compact, being a bit shorter and wider physically than the Fiio Btr5. But the noise floor makes this amp hard to recommend. If you're looking for a small portable amp for iem's I suggest the Fiio BTR5 or Lotoo S6, both which have comparable sound quality, but with dead quiet backgrounds.
dodged a bullet there

Very interested in Hilidac Beam 2 and Lotoo Paw S1, hope they can be measured here. Both support MQA which differs them from the rest.
Anybody compared them?

Just wanted to update that I've finally received the MU3X and it looks to be everything I wanted in a type-c dongle. 0-100 volume step, 5 gain stages, 5 selectable filters, simple and user friendly interface, type-c socket, connect to android and windows hassle-free, no battery to worry about, never gets hot, gobs of power for IEMs, sound subjectively good with no hiss. Pricey but I wouldn't mind selling all other dongles I have, hopefully nothing wonky crops up later.

Do any of these support a fixed output mode? I'm looking to have a super small usb dac to feed my L30. Other inputs are wasted on me and I really don't want another box on my desk so I've avoided getting another E30. The E1DA 9038D has had my eye (and is available now on linsoul) but the LTE interference issue does seem real and I've encountered it in my desk setup before so I'm hesitant to jump on it.
