Interesting that you say that, that because I've seen a very serious audio review insisting the 816 sounds nothing like the M8.

They say similar things about it and the measurements are nearly identical.
 
Thats how I heard it. I can't AB because I gave the 816 away but when I got the M8 it felt like getting the 816 back. Despite measuring flat they both are a touch warmer and more punchy than the Nexus 5 I had in between.
 
 
The 820 however uses a different chipset and posted poor numbers. But the 816 was great.

One question, can the HTC one m8 drive the hifiman he-400i?(it should be powerful enough) Or the sennheiser HD 600?(probably not)

 

[Darkseth]

If it can drive one of those, it should be the sennheiser.
Planar technology + lower sensetivity = needs more Power to drive.
 
The difference in Impedance doesnt do anything here. My 250 Ohm Beyerdynamic T90 (which i can't endure at 15/15 volume on my one m8, no volume-mods) is pretty much just as loud, as my 32 Ohm Superlux 681 (b).

Typing this on my M8 while it's driving my HE400i. It powers it fine for casual listening. 8/10 volume is what I am on.
For critical listening, you'd want an amp of course.

Thanks so much I heavily appreciate your response.

How does the HTC One M8 3.5mm quality compare to the Nexus 5?
What's this about some forced built-in EQ that handicaps the audio quality when "disabled", and what is the Harman Kardon thing?
I am using Shure SE215 and Sennheiser HD595

M8 has fuller bass, it sounds smoother. I didnt like the nx5 at all and got htc again.

Did the European M8 get hi-res capabilities after marshmallow update? Because it shows my files playing at 96/192 24 bit.

Does M8 Mini 2 feature the same quality headphones out as a bigger M8 ?

Hello, 
 
can you try latest HTC Connect for Apple Airplay?

Guys anyone can comment on iPhone 4s vs HTC m8 sound quality? I found that iphone 4s has excellent sound quality. So I'm thinking which one should I use as dap only purpose. 4s 64gb version and it's small size factor as a dap looks convenient

 

[Darkseth]

if you're using the phone itself, htc. much newer, etc.
 
If you only use it as a music player, go for the 4s, or maybe better a standalone Hifi Player? like, Fiio X3, some Cowon or something like that.
since here you won't pay for 95% the features you won't use.
 
But in terms of audioquality, the M8 is a beast (don't have comparison to the iPhone 4s).
M8 has an output impedance of 1.2 ohm or so~, an Output voltage of 1.2 - 1.3 Volt, and in addition to that, a quite high output Power (in watt), depending on the impedance of the headphone.

Short Answer: iPhone Sounds better. Although I am comparing m8 with a 5s.
 
I downgraded from the m8 to the 5s due to a big difference in headphone out SQ. 5S Sounds significantly more transparent especially in the midrange. It sounds flatter.
 
The HTC, while it does have a good amp and excellent speaker, It feels like its DAC section has recessed Mids (via Momentum Over Ear 1.0). HTC Sounds a bit more spacious, but this is possibly due to the relatively recessed mids (or Boosted Bass & Highs) compared to the iPhone.
 
HTC will sound more dynamic on high volumes; while the iPhone will sound pleasant even on low volumes. The HTC Sounds lifeless on low volumes due to the bass & highs drowning our the mids & upper mids.
