Just get the apple dongle, that also measures pretty good and is enough for most IEMs. If you think you need more power get an amp with a low output impedance.
Here the Specs from the S8.
I have the S3 and run with the Emu Purpelheart very well.
Personally the Producter is good and the price too for use every day is enough.You need not more.
For sure the S8 is better as the S3 in connectivty.
Just an FIY: the Tempotec Sonata HD Pro is the same as the S8 but half the price.

I paid $250 for my Topping D50s not too long ago, and now that I see this gizmo for $40 I think, “Eh, pass; there will be something even better for half the price soon”
That is the way of chi-fi lol. If you already got something good, waiting will just give you something better and/or cheaper.
(although perhaphs with the AKM incident, that rule might not be the case for sources for a while.)
Hello again,
Massdrop offer acttually the ALPHA & DELTA MK 2 for 28$ maybe an Option for the Apple.
It give for Android too and in Balanced version.
Tempotec Sonata HD Pro. Comes with USB-C and Lightning cables. $60. Not a ton of power, but it’s clean. Would be fine with lower-impedance, higher-sensitivity cans.
much cheaper than that on aliexpress actually, 31€ ~= 37$

Maybe I gave you bum advice, Juan? If so, sorry.
I bought the Tempotec Sonata HD Pro today to drive my Sennheiser HD 560s (120 ohm impedance, 110 db sensitivity), and I must admit I’m underwhelmed so far.
I know this is a dongle and not a nuclear substation for power, but it seems like the Sonata HD Pro only gives me about two more clicks of volume than driving the 560s straight from my iPhone 12 and the Apple Lightning DAC dongle. The sound isn’t really cleaned up THAT much, either. I expected more considering the praise here and other audiophile lairs online.
Am I doing anything wrong? Or were my expectations too high? Or does this prove again that the Apple Lightning DAC dongle is the best $9 bargain in hi-fi?
Thanks.
Juan:
A very helpful dude at Audio Science Review just gave me a tip that transformed this thing.
The Tempotec Sonata HD Pro recognizes the HD 560s as low impedance cans and switches automatically to its low gain mode. You need to follow these steps to fool the Sonata HD Pro into thinking the HD 560s need max power:
- Connect the 3.5-mm adapter that comes with the HD 560s into the Sonata unit. (The HD 560s come stock with a 6.35-mm plug)
- Connect the Sonata with the 3.5-mm adapter to your source (phone or laptop) with the provided cable so the source recognizes the connected HD Sonata.
- Connect your headphone cable into the 3.5 mm adapter connected to the Sonata and your source.
Wonky as hell, part of the charm and frustration of Chi-fi devices. But damn if it didn’t work. I’m listening comfortably to my 560s from my iPhone 12 at half-volume, with better fidelity because of the additional power.
I don’t need to do this trick with my Meze 99 Classics and Moondrop Starfield because they’re both low impedance and high sensitivity and don’t need the high-gain power. Hell, they both really don’t need amping, but they sound better with the Tempotec’s amplification.
One of the reasons I like the Tempotec is that it comes with a MiFi (Apple)-certified adapter. No need for the Apple USB Camera Connector. I wish the Tempotec cable was sturdier, but that’s the price of a $58 Chi-fi device, I guess.

Hi OP! What did you end up getting? I’m planning to get a similar setup( TC35i + BLON BL03, cable upgrade w/mic). I’m worried about the compatibility and if the mic will work.
Hello people, I too am curious about an iPhone Dongle. I like the form factor of the provided Lightning Dongle, and after searching the web, I stumbled upon one on HiFiGo:
If you looking for recomendations i’ll leave this here. I got TC35B and it arrived today. Built like a beast, sounds amazing, powers fine. Also very small form factor.

Thanks for the trust.
I think the TC35B is for USB-C only. Upon further search, the TC35i is for lightning/iOS, so I’ll give it a look.
Edit: found another dongle adapter, but this time it’s made by DD HiFi:
yeah, there’s both versions. Also 2.5 and 4.4 
Okay, I think I found a new rabbit hole:
DDHiFi sells this adapter:
And in my mind, perhaps it can be used for the THX Onyx?
I know for a fact that the Apple Camera Adapter should be used with the THX Onyx, but the Onyx needs to use it’s USB C to A adapter. So I was thinking that maybe this DD HiFi adapter can expedite that process, and let the Onyx use it’s USB-C?
Sorry, no clue there. Havent use ios in 10 years
