Sennheiser HDB 630 Wireless Over-Ear Headphones - Hi-Res Audiophile Sound, Adaptive Noise Cancellation, Parametric EQ, 60 Hour Battery Life, Includes USB-C Low-Latency Bluetooth Adapter - Black

These sound amazing for audiophile sound. I still have the momentum 3 overear headphones made in 2020 that i used daily until 2023 for work to jam out between taking calls on a remote IT job. They'd last all day easily and to this day 6+ years later still have over 95% capacity on the battery. The momentum lineup has a more bass skewed and rock/metal or techno/rap sound profile. The hdb630 has a very neutral sound profile with only a little harshness in the upper mid range that the parametric eq in the Sennheiser+ app, and external eq apps can easily correct for me. Its noticeably less punchy in bass heavy music, that gives it a bit more balance than the momentum line overall though, especially in lower mids. The more neutral tuning helps sound staging be extremely good, tone separation be top notch and when you gdt aptx adapive with 24 bit/96kbps through the bt700 dongle it literally sounds better than a cd, even 16 bit/ 48k aptx adaptive (which it gets more commonly due to the aptx adaptive codec auto negotiation of best sound and speed balance) its barely inperceptable the audio quality difference. My only complaint is the earcups are a bit small on my ears. I found a good way to correct it so it doesn't feel awkward though, mainly with my left ear, it seems to sit more naturally on my right ear. You extend it further than you need to for tight head adjustment, ensure your ears are fully inside the cups, or where they're comfortable and wont slip out and sound is good. Then push the headband down in the middle until its as tight as you comfortably like it. That has made them comfortable for me on long sessions so far.
