# 320 kbps MP3 -> laptop sound card -> studio headphones = what is the bottleneck?

(Asked by: username_0 on 2013-12-07)

I am usually listening to

* a) 320 kbps MP3
* b) Spotify over WiFi

on my

* c) Samsung Galaxy S4
* d) HP laptop with internal sound card (I can't even google what card is there)

over

* Sony Mdr-V6 closed headphones.

What is the bottle neck in my sound quality? What should be my upgrade path?

1. upgrade headphones?
2. buy external sound card for the laptop?
3. buy headphones amplifier?
4. improve the audio source?\*

## File format

Bit rate tells surprisingly little about quality in the case of mp3 files. There are old encoders where no matter how low you set the compression, there will always be audible artifacts. But LAME and the like have long gotten over this, and [properly done 320 kBit mp3 is for listening purposes lossless](https://video.stackexchange.com/questions/8382/is-there-a-losslessly-compressed-audio-file/8383#8383), just like [CDs are](http://xiph.org/~xiphmont/demo/neil-young.html). Note anyway that mp3 is an outdated standard; I'd like to recommend switching to OGG Vorbis but practically this wouldn't gain you anything.

## Network

What digital connection you use to transfer the file from the source to the DA unit has no influence on the sound whatsoever1. WiFi is fine as long as its avarage transmission rate can keep up, which should never be a problem nowadays (apart from complete dropouts if the connection breaks down somehow, of course).

## Sound card

Laptop on-board sound cards are horrible, so off the top I'd say that's your bottleneck. *However*, the one thing they usually manage quite well is driving headphones. The main problems that such sound cards have are

* Awful mic preamps.
* Bad AD/DA units.
* Insufficient (or no) shielding against interference from power supply bursts etc.

You don't need the mic inputs. Even low-quality DAs of today can actually reproduce properly bandlimited audio quite faithfully. And the interference issues mostly turn up when you connect to some other audio device (with ground connection), but not so much with headphones. The headphone amplifiers themselves aren't great of course, but since that's quite an easy job electronically they still don't have easily audible influence on the sound. One remaing problem is high volume levels, especially in mobile devices, for power-supply (as well as, possibly, heat dissipation) reasons.

You may try an external sound card, it *might* improve you listening experience; but perhaps not significantly.

## Headphones

Like any kind of speaker device, those actually have more influence on the sound than any properly designed purely electronic component2. That's often not so much considered a flaw as a characteristic; HiFi speakers aren't really designed to transmit with flat response at all, but to transmit "nicely sounding", which obviously isn't quite well-defined.

Its most likely your sound card. HP is notorious for using extremely cheap components on non essential hardware, such as your soundcard. It is the same way with all 3 of my HP computers.
