Bose qc35ii. You can find them used for half your budget. You can use them wired or wireless. They have as much or more sub bass than the Beyer dt 770 without the peaky treble. I know audiophiles sneer at bose headphones but this model is above the rest in the bose line according to my taste...

There is now the creative aurvana live se. You can buy it with it's companion dac or just the headphone. Still a great price for just the headphone. Maybe the best closed back budget headphone you can buy. I don't think there's a better headphone at the price, depending on one's taste of course...

Same here, I've owned my m40x since Jan. 2015, 8+ years. Since then I've bought and still own a number of closed back and open back headphones. I replaced the earpads with a pair of Yaxi pads, same size but much more comfortable than stock pads. The bottom of the headband is completely worn...

What is that that your headphones are on.? Where did you get it?

I would definitely consider the philips fidelio x2. They're not the most technical or neutral headphones but they're still enjoyable to listen to, especially at the price they go for these days. They're open back so they let external sounds in and they leak sound out. But for under $500 you...

Yea it's hard to believe that that much bass boost would sound good on any headphone.

Yea, I'm pretty sure that's it. At the bottom of the screen there's a box to write reply and under that box it says post reply. Thanks for your help

Thanks, I have another question. Does the btr5 have a battery level indication on the btr5 itself or just in the app? Any indication on the btr5 that the battery is close to running out?

I listened to that track at a volume level as loud as I would ever listen and no cracking sound. Let us know how you make out on that track with your new pair.

I wouldn't say the akg k371 has weak bass. I own audio technica m40x, creative aurvana live se (cal se), bose quiet comfort qc35ii and senn. momentum3 wireless and they all have, to a greater or lesser extent, elevated bass; which I like. Compared to these headphones the k371, which I also own...

Great advice.

It won't be 400hz and 3.5khz exactly. From 400hz and below the frequencies will taper off gradually. From 3.5khz and above the frequencies will also taper off gradually.
