Got this to replace my AirPods Pro 2 after reading rave reviews. Frankly I think they’re overhyped. They sound good but not great. A bit too bassy and the mid bass is a tad boomy. ANC wise, though it cancels lower frequencies well, I can clearly hear the chatter of people in front of me, which was not the case with the AirPods Pro 2. Fit wise, I feel like they were gonna fall out anytime. I changed to Spinfit tips and it felt more secure. The mid bass tightened a bit too. The magnets are rather weak, which I’m surprised. Overall it’s not a bad purchase but at this premium price point, I expected more.

I mostly care about sound quality. These are the best sounding earbuds I've ever had ,although the Senheisser MTW4 are pretty close. The sound is crisp and wide with great beat, I'm not a sound guy but that's how I would describe it. The battery is also good, I don't have issues with them running out of battery, connections also great, no issues even with LDAC activated, noise cancelling is good for me as well as ambient sound. Not sure how they are compared with others as the apple ones. But for me is good enough. The case is also small which is good for transportation, one thing I complained about the Senheisser ones, even though that one looked and feel great, the size not as good. The app is simple and easy to use, I might be missing the custom sound feature from the Senheisser app, but maybe I don't need it.

I bought these to replace my Sony WF1000X3's (yes, now two version old) whose charge controller died after 5 years. The Technics offer a notable improvement in sound quality particularly in instrument separation. The bass feels entirely different from the Sony's with the Technics feeling as though the bass were in my head rather than near it. Try the different equalizer settings in the app. These sound better somewhere between the Dynamic and Treble+ settings. Bluetooth connects quickly; within 2-3 seconds of taking it out of the case; a big improvement over the Sony's 15-20 seconds. While the Technics is often described as being not as good as Sony's latest offerings, I expect it to be as good or better than the XM3's. It isn't. It's good, but it has two limitations. The first is that it's effectiveness is driven greatly by the quality of the seal from the eartips, and it's challenging to get a good seal. They need to be pushed in your ear solidly. I recommend going with a smaller eartip than you would expect. The stock eartips work pretty well. I've tried memory foam tips which were amazing on the Sony's, but whose comfort is mediocre due to Technic's mysterious decision to make the ear bud speakers oval and cumbersome to replace. The silicone SpinFit tips provide the best balance of comfort and isolation. Even with a good seal, the ANC isn't the vault-door shutting finality of the Sony's. High pitched noises enter pretty easily with some sounds, like plates being clanked together seem to bypass the ANC entirely. Right now I have Indigo Girls playing on the stereo and even with these earbuds solidly in my ear, the lyrics are understandable even though the music is inaudible. The app's ANC fine tuning does almost nothing to improve this. The stock configuration of the earbuds will result in a noticeable delay between audio and video. This can be remedied by turning on the LDAC codec in the app will resolve this, but at the cost of multi-device connectivity and battery life. Battery life is excellent so far even with LDAC turned. I have yet to wear them for more than 3 hours continuously at which point they were at 56%. The case brought them back to full charge in 10 minutes. We'll see how these hold up long-term; hopefully longer than the 5 years the Sony XM3's survived, especially since the Sony's really died after 3 years, but at least it was possible to change the batteries. Modern earbuds have put an end to that.

I am a slightly reformed earbud junky. I have owned or own almost every credible earbud in the last five or so years. I use both an Android and an Apple phone, an iPad Pro, and a Dell XPS laptop so I am ambidextrous when it comes to devices. I owned the first gen Technics buds and I mostly really like them. Like the Sony buds, they were a bit big but it was a hell of a comeback for the Panasonic owned HiFi company. My current daily drivers are the Sony 1000XM5’s and the Apple AirPod 2 Pros. I love them both. However, the Sony’s are still a bit big and the multi connectivity, while present, isn’t the best. The AirPods are awesome but aren’t great for non Apple products. So, after putting this purchase off for many months, I finally pulled the ripcord and got these. They are awesome. Here is the breakdown: Sound: This is how I start every review on buds because sound is the main purpose of any bud or headphone. The sound here is amazing. This is a single 10mm liquid filled driver that is new technology in a bud. It creates deep sound that is a bit bass leaning. You get strong separation between the low, mid, and high tones. The sound here crushes the AirPods and is equal to the Sonys in my opinion. There is support for LDAC and LE Bluetooth codecs. However, these sound amazing without the high end codecs which is good for Apple fans. Those that love lossless audio though will be glad to have these on board. The sound is almost enough to recommend these but read on because there are many more reasons. Active Noise Cancellation (ANC): This is one area I think these buds don’t wipe out the competition. The Bose buds and the Apple AirPods are both a bit better. These are on par with the Sony buds for me. Good but not the best. There are a lot of adjustments in the app but I just leave them on adaptive. I think these will be great for a plane trip as these do a great job on low end noise. Sudden sharper noise gets through though. I do love that these don’t make you feel ear pressure that some buds give you with it on. Overall, while not class leading, the ANC here is still very good. Form Factor: These won’t be to everyone’s liking but they are pretty dynamite. These are smallish stemless buds that have a nice soft finish inside the buds with a nice metal finish on the outside. The look and feel great. I find them comfortable for long periods. Call Quality: The class leading AirPods are still the best, but these run a close second. Technics embedded AI that can identify your voice, enhance it, and cancel out noises around you. Some reviews I read say that this process can end up making you sound a bit robotic but I haven’t had anyone comment on it and I have been asking. Very good calls all around here. The case: I always rate the case in earbud reviews because you frankly interact with the case more than the buds. This is a solid case overall. The brushed metal design is great. It is a good slender case that is similar in size to the Sony buds but metal not plastic. There is a single LED and it does support wireless charging. It is a great case with one nitpick. I wish the magnets were a bit stronger. In a purse or a gym bag, you may find buds flying around. All the other stuff: Battery life here is closing in on class leading. As long as you aren’t using the hifi codecs often, you will get over ten hours of use. Awesome. Connectivity is stable and fast. I have these connected to both of my phones and they connect to both immediately upon pulling out a bud. Further, these easily pass back and forth between the devices as needed. I was on one call today and got another on my work phone. It was ringing me to let me know I had the other call. Awesome. There is Spatial Audio here that sounds great especially for a movie. Lastly, the Technics app deserves a nod here. It is a really great app. Where the Sony app gives you everything, it is very convoluted. This app gives you sound customization, ANC control, and more but without being difficult to use. Oh, and there is a Find My component to the app that allows you to make sounds if you lose your buds or see where you last had them with location data. All so good. I will just say this about what Technics has done here. If these aren’t the best all around buds on the market, they are darn close. I am a huge fan and strongly recommend buying them. **UPDATE**I have had these a for a long time now and I still use them regularly. I ended up getting a set in the new blue color as well for review from Amazon and I love them even more. I also recently got the AirPod Pro 3’s and, while I love them, I still use these exclusively at the office for their multipoint connectivity between my laptop, iPhone, and Fold 7. They just do everything well and are as close to perfection of any buds I have ever owned. Still strongly recommending today.
