Headphones?

Postby robgil » 08 Dec 2017 22:52

So I need some headphonmes for my daughter, she wants them for her tablet but also for hifi music listening.

What spec would be best? Tablet can be a little volume shy. I'm looking at something like these,

https://www.maplin.co.uk/p/sennheiser-h ... ones-a62xu

Frequency Response:
19 - 21000 HzHz
Sensitivity:
108 dBdB
Impedance:
16 ohmΩ

https://www.maplin.co.uk/p/philips-shl3 ... ones-a66xa


Frequency Response:
10 - 22,000Hz
Sensitivity:
106dB
Impedance:
24Ω

Would a higher impedance be better or a lower one for a volume shy tablet?

You want to match the impedance as best as you can.

Many smartphones and tablets sound outputs are in the area of 10 ohms, so theoretically, your 16 ohm headphones would be a better match than the 24 ohm for a tablet.

I'm too lazy to do the math, but I doubt that you would notice the difference in volume between those two headphones. #-o

Having said that, it's really a 600 ohm headphone that would be a problem, either of your examples should do fine. :D

I'd don't think it really matters if all you're spending is $35.00 dollars. At that price point they all sound the same.

You could try some Superlux HD-681. Lot's of mods and info about these on the net. Cheap to buy, good sound to my ears. I upgraded the ear-pads with cheap velour pads on eBay. I also upgraded my plastic head strap with a leather one that I made. It really isn't any more comfortable, but it looks good and cost me nothing.

Here's a review: https://www.cnet.com/au/products/superlux-hd681/review/

If you're finding impedance a worry, get a cheap headphone amp. But not really necessary in my opinion as all cheap circa $30 headphones are going to have suitable impedance for smartphones, tablets, etc.
