Newbie help with headphone gift choice.

The Sony's are comfortable, durable (only pad flaking in 30 years) and easy to drive.

The negative is static electricity causes "ear shocks.". Not recommended for dry environments. Can be mitigated with anti static spray.

I replaced them with Focal Listen which also come with BlueTooth. 

Thank you guys for  your info. I appreciate it.  Budget is about $75 - $100. So the four I listed are in that range. We live in New Mexico so it is dry here. But my brother's place doesn't have any carpets if that makes any difference. Thanks for the head's up on HifiMan set drivability. (Is that a word?) I didn't think about about that. I'm tempted to try a pair for myself but my android phone would not be able to drive them. My brother would use them with Apple laptop and Apple iPad. So maybe hifimans wouldn't work. Decisions, decisions. Thanks again. Happy holidays.

Audioquest Nightowl or Nighthawk, if you can find them.

Yeah, you want some higher sensitivity ‘phones if he’s driving them off a laptop or tablet.  First, you did some good research and identified some really good candidates at the price point.  Hard to say without knowing your brother’s sound preferences, but if he’s ok with a semi open-back design I’d go with the AKG, but if he needs a closed headphone I’d go with the Sennheisers as they tend to go straight down the fairway sound wise and not offensive in any way so very safe.  He’s clearly not an audiophile so your first choice should be whether he’d be better off with sealed or open ‘phones.  After that I don’t think you could go wrong with any of them and I’m sure he’d be thrilled with any you so aptly chose, but u gotta get the closed versus open thing right.  If he’s in a room with other people around or with outside noise you want closed headphones, and if not I’d go open.  Hope this helps!

The Sony are clear and crisp sounding. The Sennheiser and AKG tend to be warmer and a bit dull. I haven't heard the AT.
