iphone 4 sound quality - Page 17

post #241 of 332

I do hear hiss with the TripleFis and my now-departed UM2s on my iPhone, but it's at the same level (if not lower) of the Clip+.

In fact, I'm thinking of getting rid of this thing. It drops calls when you hold it the wrong way, randomly kicks calls into Facetime or speakerphone, and hisses.



I agree with the noise out of the jack. Using IE7s here. Much much noisier than my Clip+. However it does have pretty good soundstage and detail suprisingly

I've really gotten to like my iPhone 4 as a source with my SM3's. I hear a little bit of hiss, but it pretty much goes away if I turn on airplane mode.

Strange, my tripe-fi's are dead silent with my iPhone 4. I wonder if there was change made in different batches.

I too hear a little bit of hiss with my Fidelity Custom Triples (similar but cheaper than the ES3X) and the iPhone 4 hp out. But it is *little*

I will soon have access to both an iPhone 3GS and a 4. I will do a clear test just out of curiosity with the two devices to see if there really is a difference in sound.

 

Headphones used will be Klipsch S4, Shure SRH 840, and Sennheiser HD650. All unamped straight through the phones at a constant relative volume using constant songs.

 

Lets see if there really is a big difference. The only thing that might affect the test is that my iPhone 3GS has been used for countless hours while the 4 will be very new (for you burn in believers)

Throw EQu on the iPhone 4 and the SQ is equal to a Rockboxed player - 'nuff said!!!

post #247 of 332

I find that iphone 4 straight out to my ES5 one of the best setups I have. And that is among some setups you see from my signature block.

^ That is not bad at all. The iPhone 4 is for sure the best portable player I have heard - together with the iPad which is not bad either.

Does anyone know the output impedance on the iPhone 4?

post #250 of 332

I tried an iPod Touch 4 and that was much better SQ wise - no hiss. I wouldn't think the chips in the iPhone 4 and iPod Touch 4 would be different... so maybe I just got a bad iPhone 4

most likely just ear sensitivity. Some people just don't hear hiss and some (myself included), hear it from everything.

The most impressing thing is the dead silence on my iphone4 and it does even better than sony x1050 and b&o beosound2 on bakcground noise!

Hah. Wouldn't life be easier if we didn't hear hiss? It's a nice thought, being able to be less discriminating in choosing players. Anyway, when I tried the iphone 4 I thought the SQ was quite impressive. Now, nearly every decent modern source is decent these days, but relative to my clip I noticed there was slightly better stereo separation. Now that there's a good EQ for the iphone, it's a very impressive source. After the cowon J3 and its BBE, the iphone is one of the best.

Perhaps it does, if it doesn't have a flat FR and you like its colouration. Or maybe it's just another case of someone imagining things again, certainly wouldn't be the first time that happened in audio.
