Features and Convenience
1) Sony 1000XM5 - These are hands down the champs of features. This is my favorite travel headphone. Tied for 4th with the Dali iO-6 and PX8/PX7 S2 for battery life. The best app, ANC, and phone call quality on the market. When on the phone, you can be standing in the middle of a construction site and the person on the other end will think you're in a library. It's app-based EQ is hands down better than all the others on this list. Speak to chat, which is the ability to start talking and have the headphones automatically pause your music and turn on transparency mode, works well in a work environment. Quick attention, which is the ability to temporarily turn on transparency mode by placing your hand over the ear cup, is very convenient. I could go on all day on the many features, but for the sake of time I won't. Most know about all the features this headphone offers, but if by chance anyone has questions, feel free to reach out. This headphone is in a league of its own when it comes to features.
2) B&W PX8/PX7 S2 - Excellent app. Love the ability to manage your bluetooth connections in the app. Makes it very easy to connect to multiple devices without digging through settings. Other headphones in this list can now do this as well, but I give B&W the credit because they were the first, I saw do it. Solid phone call quality. Tied for 4th in battery life with the Dali iO-6 and Sony 1000XM5. AptX Adaptive for Android users. There's a simple EQ in the app which is an added feature over the original PX7. However, the biggest, and honestly my favorite feature on these headphones, is the ability to keep a bluetooth connection while using them with a wire. This is so big if you use them for gaming or movies on your TV. If I get a call while gaming, I can hear the ringer and answer my phone without having to take the headphones off. LOVE THIS FEATURE. Another cool feature worth mentioning is that the app will stay connected to the headphones wether you're connected to your phone or not. This is also an underrated feature seeing as how most wireless headphones rely on app features to get the most out of them. This also gives this headphone an advantage when managing bluetooth connections. Say you're connected to your TV and Laptop; you can still manage your connections without having to be connected to your phone. Also, the PX8/PX7 S2 is currently tied for second with the AirPods Max as my favorite travel headphone. My biggest gripe is that you can't use these passively. I don't count this against it too much as headphones like the 1000XM5 and Momentum 4 can be used passively but they sound horrible. As I'm sure you can tell, this headphone has a couple of my favorite features. If it's ANC and call quality were better, they'd be ranked above the 1000XM5 for me.
3) B&O H95 - Excellent app that includes a simple EQ that saves to the headphones. Multipoint bluetooth, dials for different levels of noise cancelling and transparency, excellent call quality, and the 3rd best battery life behind the Solitaire T and Momentum 4. AptX Adaptive for Android users. Biggest flaw for me is you can't manage bluetooth connections from the app.
4) Momentum 4 - Very good ANC, transparency mode, and phone call quality. Like the PX7 S2, can manage multipoint bluetooth connections via the app. The 2nd best battery life currently on the market with 60 hrs runtime. Also has a simple EQ. App is a little sluggish when compared to others on this list. Also, unlike the PX7 S2, you have to be connected to your phone to use the app. ApX Adaptive for Android users.
5) Solitaire T - Very good ANC, call quality, and transparency mode. Battery life is the best on the market at 70 hours. Excellent size for travel and commuting. APTXHD for Android users, with LDAC promised in a future update. This also has one of my favorite PX8/PX7 S2 features in the fact that you can remain connected to your phone via bluetooth when using these with a wire. I wouldn't be fair if I didn't mention that these do have a couple of missing features that may be a deal breaker for many. First, these don't have a detailed EQ in the app. They have a couple of presets, but that's it. Also, they do not have multipoint. You can only connect to one device at a time. These also have issues with its touch controls that have been improving with firmware updates.
