beyerdynamicFree BYRD Grey True Wireless Bluetooth in-Ear Headphones, Active Noise Cancelling, Long Battery Life, Microphone, IPX4, Sound Personalization and Alexa Built-in

These are able to compete with the FIIO fw5 buds sound wise certainly, although they aren't really audiophile buds... I'll explain. No LDAC or high end codec on the Beyerdynamic Free Byrds unless you consider aptx adaptive high end. Here's the kicker, IT DOESN'T MATTER. I use AAC on these Free Byrds with my Google 6 Pro phone and the sound is absolutely amazing. The air around the instruments is amazing, the sound is colored, so not audiophile, to bring you deep bass with thick mids, the sound is warm for sure but without too much bass and without drowning out the highs which are readily audible but not sharp at all. I can hear every note from every instrument presented easily. Also to be noted is the fantastic soundstage with pin-perfect imaging. It's uncanny how good these sound as sound comes from exactly where the artist meant them to come from, literally all over the place... above your eye, check, outside the width of your ear, check, deeper in the back of your head, check. The entire codec war is going to be null and void with these buds. CLEAN sound, loud and clear on the spot and they can play loud if that's what you're in to. Use the hearing test to personalize the sound to your hearing abilities and it only gets better. I have a ton of money in audio and qualify as one of those strange audiophile people and I'll tell you quickly these things are absolutely awesome sounding, for the price its absolutely a no brainer. I also have Beyerdynamic DT990 Pros and the Beyerdynamic Amiron Homes both of which are no slouch in the audio dept and these buds just make me shake my head. Its comparison to the 770 closed backs is spot on but the buds sound wider. No way was this a rushed product thrown together just to get on the market, these are WELL thought out and executed even for picky listeners who want to hear the mids also. This was Beyerdynamics warning to the others, "We are here now, and we're not playing games." Buy with confidence...

They have excellent sound quality, great bass, no clipping, just 10/10 on that front. I don't have much need for noise cancellation but they seem to do a pretty good job, just know I've dropped my earbuds a few times over the last few months on concrete/tile and the ANC on my right bud has gotten pretty fuzzy/warbley so I had to disable it, but otherwise they're still 100% functional.I've had a lot of annoyances with other wireless earbuds that are too flimsy or had touch buttons on awkward places that could be activated when out of your ear, which made them extremely annoying to handle. So I love that these are bigger and have a lot more space to hold onto, never had any accidental button presses.They have a sensor to detect when they're in ear, and sends a pause/unpause to your media when you take them out and put them back in. I really like this feature but some may find it annoying, I'm not sure if it can be disabled in the app.I have encountered ZERO syncing issues; I've had wireless earbuds that stop connecting with each other, that try to connect individually with my device, that refuse to connect entirely. I've never had any of those problems with these earbuds.They have an 8-9 hour full charge plus like 3 full charges in the case. If I remember to put them back in my case when I step away from my desk I never run out of battery.Something people don't tell you about wireless earbuds is that they're not really ideal for voice calls and listening to media at the same time, because the headset driver uses half of the Bluetooth bandwidth for its microphone, this makes all of the sound they output very low quality. This is a problem with Bluetooth 5.0 and not the devices, however, it will only use the headset driver and not output any sound to the main stereo output when connected to a call on windows. So even if you have an external microphone, you're still reduced to halved audio quality when using these for a call.

These have a great sound. Wish it had a standard parametric eq so sound could really be customized, but figuring out how to match the ear profile along with the provided parametrics (v-shape) can pretty much accomplish something you'll like. Oddly enough the foam earbuds with these reduce bass, the softgels actually increase the bass. Could be how the tips fit in my ear issueFor a wireless earbud the bass, mid range, and sound are 10/10. Excellent power and dynamics. Really superb sound. Definitely in/above the class of the sony wxmf1000s depending on what you like.The fit of them does leave a good amount to be desired. Feels a bit loose I wish they were tighter or had a fin to keep them in place.Earbuds are a personal thing. Everyone likes a different sound signature, so no reason not to try them all out and see what you like. I personally like to have many diff pairs so my ears don't get bored of the music if that makes sense.My fav earbuds for reference:1. Jaybird Vista (great sound, excellent mids, comfort 10/10, terrible voice mic, not even useable, great for workouts)2. Audio technics eahz 60 - (great all around sound, comfort 9/10, excellent mic, great all around headphones)3.Beyerdynamics - superb sound stage 10/10, comfort 7/10, excellent mic, my favorite listening experience4. Sony wxmf1000's - great all around, great noise cancelling, mid range is pretty cool, albeit slightly muddy, comfort 8/10These are all great headphones imo.
