How good are my old ears ?

[BobB]

In readiness for a new mini Hi-Fi I have taken advantage of "black Friday" discounts to buy headphones, Sony WH-CH720N. After about ten hours of use I used my iPad mini 6 to compare their frequency response with an old pair of Senneiser HD458BT headphones. It came as a surprise that there was little or no difference. Then comparing the iPad speakers I got almost exactly the same. Results were :
Sony 20 Hz / 9.0 kHz
Sennheiser 23 Hz / 8.8 kHz
iPad 20 Hz / 8.9 kHz
So, is it YouTube or the iPad that is limiting the audible frequency range? What do the experts think please.

Go with the one that sounds best

@BobB  Depends what age you are.

Youtube and BT are not the best for quality but should go beyond 10kHz.

The spec sheet on the Sony cans has this -
Frequency response:
7 Hz - 20 000 Hz (JEITA) (when connecting
via the headphone cable with the unit
turned on)

My  headphones and speakers reproduce much more than I can hear now and even as a young bloke I couldn't hear some things that others could (like TV sync signals 15.625kHz, I think)

Get the 1kHz and 10kHz files from here or somewhere else and play both on your ipad.

Thanks Mark.

Tested, it's the iPad at fault !

Before youtube became restricted here I listened to classics using Audio Technicha M40x headphones and though not as good as cd's it sounded ok. Now comparing the Sony headphones to the M40x's both are really good with the better dynamic range being for the Sony CH720. For a 73 year old another test says I have "good" hearing. I'm just glad I can enjoy classical and pop music still !

Glad you sorted it.
Always good to be able listen to and enjoy our favourite tunes.
