Apple iPhone 8
Portable High-End Equipment
Music Player in Glass Case with Aluminum Frame and Stainless Steel Chassis
01.10.2017: Listen to my favorite album: The Best Of The Art Of Noise (1992), 2. Title: Yebo (Mbaqanga Mix). This is ideal for testing low-frequency playback! Also very good for testing is title 7: Legacy.
This is a synthesizer sound that is not objectively suitable for testing the sound quality of a music player - electronic music sounds good on every device. But I know this album inside and out, and I've heard it quite often on MP3 players (constant-quality coding, dynamic data rate up to 320 kbit / s).
For the objective test of the sound quality I have used musical titles with acoustic instruments and very often heard musicians.
Also the hearing test CD of the audio magazine HiFi was very helpful in the objective test of the acoustics.
Ruler-straight Frequency Response
The Apple iPhone 8 can show correctly that it has pulled down to the low-frequency range a ruler-straight frequency. Otherwise, the bass would not be so abyssed, undistorted and clear (unfortunately I can not measure it - and no test magazine has published measurements).
Only gsmarena.com tests and always publishes the frequency response diagram!
Because of same audio technology they test only the Plus models from Apple.
My hearing is confirmed - the frequency response is from 18 hertz to almost 20,000 hertz as pulled with the ruler and thus better than with many other smartphones.
The signal-to-noise ratio is also excellent. Because the latency is extremely low, iPhones are liked by musicians and DJs.
Bottom line: the best high end music player - but not with the included Apple EarPods!
These have a too weak bass reproduction, but otherwise offer quite linear reproduction (writes the press).
Since I do not think of such gimmicks, I have not even unpacked these EarPods.
My audio test equipment: As headphones I use the Sony MDR-EX90LP on the Bluetooth audio transmitter Samsung Level Link.
This in-ear earphone in studio quality ensures unadulterated playback.
