Sennheiser Momentum True Wireless 4

~ Veselin ~ 8 Comments

Apart from buying books, I like getting myself little gadgets on occasion. Over 2025, that was mostly audio equipment. I got two closed-back headphones – the wireless SteelSeries Arctis Nova 7 and the wired FiiO FT1. I also purchased an external microphone, which is waiting for the right moment be featured in a post. My last addition for 2025 was the lovely Sennheiser Momentum True Wireless 4.

The original intent for getting earbuds was to use them as a backup. Maybe try using them for calls, replacing the FiiO FT1, because they offer better isolation.

In the first days of use, I attempted taking calls with the earbuds. Many of my colleagues use earbuds and I assumed that would improve my setup. However, it didn’t work as well as I hoped.

  • They’re Bluetooth and have a very slight delay, which I can sense and it bothers me
  • I need to manually select the mic to ensure I use the right one is in use before each call
  • I experienced setup anxiety

So, although I could use them for calls, I quickly rolled back to using wired headphones with no mic and enjoy an axiety-free setup. Despite that, they’re still the headphones I’ve been using the most over the last 2 months.

  • They’re really pleasant-looking and a real joy to keep, hold, and carry
  • Fit well in my ears
  • The active noise-cancelling is so good that it makes me disappear into my own bubble. Particularly useful when watching my kids play with friends – the ANC allows me to read a book
  • The case is light and I can carry it everywhere, even when going for a walk
  • They charge quickly, drain slowly, and don’t make any unwanted sounds

Most of that can be said for any good quality earbuds. However, I own an earlier version of the Apple Airpods they were never anything more than a device I don’t want to touch, use, or carry. The Sennheiser exceeded my expectations and became part of my life. I’m not a typical user. I don’t use them outdoors, like most young people I see on the subway. So my recommendation should be taken with a grain of salt.

For my use case, they’re lovely. 5/5.

Opus

Claude Opus is my current most favorite model. I had a few blissful months of using it. Generated some good PRs, got stuck in debug loops not as many times as with previous models. I ended up extending the spend limit multiple times.

After burning through far too many tokens, I had to stop and think. Is my usage really appropriate? Is it worth thinking how much tokens each prompt consumes? Is it because of the MCPs? Why does it make all these API calls to my dev server? How much does all of that even cost? It’s not clear from the dashboard at all.

While I’m rethinking my life’s choices, I switched to Codex and GPT 5.2. I feel like between the 4 AI editors that I have, I may have enough agent time available to last until the end of the billing period.

Being stuck with one option is not ideal. The situation is not like I have to write code without agents but my overuse of Opus is giving me a glimpse into a future where these models may start costing as much as people.

Cats

First cat photo dump of the year! After all that winter hiding, the weather got warmer, and I had some cat spotting over the last few days.

From left to right,

  • The guardian of the hot water leak – I featured both the cat and the hot water pool in November. Despite continuous re-digging, no progress with the leak. It’s still there, and the cat is still keeping it.
  • Two and Three are probably male cats, I took the photo moments before their feeding time.
  • And four is a street in Yavorov, with the protected pavement.

The text says “Humans, bro.” and was painted by a cat.
