Technics Reference Class Hi-Fi Wireless Earbuds, Dolby Atmos, Head Tracking, Adaptive Noise Cancelling, 3 Device Multipoint, 10-hr Battery, Wireless Charging, in Ear Headphones - EAH-AZ100-K (Black)

I love these so far. I've had them about a week. Pros: Fit well Comfortable Price on sale is great Features Sounds quality is excellent! Tight, clean, punchy and warm bass. Clear, low THD throughout range, mids and high are linear to input with strong bass bias that can easily be configured to your desired listening pleasure through the apps equalizer. Connectivity is great, solid lossless options. Nice, small case Battery life is spectacular Cons: The ANC seems mediocre. I have foam earbud tips coming to help seal the ear which has helped other earbuds I've had really cancel out the sound around me.

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.

Amazing sound! Best I've ever heard from a set of earbuds. I moved up from a cheap pair with no ANC, and the difference in quality is immensely noticeable. I spent WEEKS mulling over which brand and model to buy. I'm a casual audiophile, so I wanted incredible sound while also factoring in comfort, features, battery life, and user reviews. I narrowed down my options to this and the B&W Pi8, which I knew would also be a good choice. The reason I chose this over the Pi8 is use reviews. Nobody complains about the sound quality of the Pi8, but the overall user experience for the AZ100 was higher, so that swayed my decision. Let me tell you, brother, I am more than happy with my choice! Here is what I love about this product: Sound quality: Listening to Ultra HD music with LDAC enabled is a religious experience. I'm listening to some music I've heard a LOT before, but it's an all-new experience for me. It's like falling madly in love with the same person all over again! I prefer stereo mode, but using positional audio with Dolby Atmos and head tracking is a nice option, and I've found it to be really great on certain tracks, especially those specifically designed with 360 audio in mind. Comfort: My old, cheap earbuds were pretty good, for the price, but I had to fiddle with them a lot to get to stay in and feel okay. Once you go through the guide to figure out what size tips to use, these earbuds "lock in" better and feel great. It's like I forget they are even there. The longest I've ever used them so far is two hours straight, and I felt zero discomfort. Noise cancelling: Impressive! I've never experienced ANC before, so I cannot compare it to Sony or other brands, but this is a game-changer for me. I live in a very quiet house in an extremely quiet neighborhood in the middle of nowhere, and I thought ANC would be overkill at home, but I was wrong. It's crazy how much ambient noise there is that you don't even think about. When I turned ANC on at home, I think I audibly gasped! I had never "heard" so much silence before! 😂 When I started listening to music, it was something special, and I knew I had made the right choice to spend good money on a premium product. Customization: The app lets you adjust equalizer settings to your liking, which is a must for me. I know this is standard for premium earbuds, but my last one only had presets, and no matter what I did, the bass was always too much, even with the "Bass reducer" setting. I don't understand the appeal of the power frequencies overpowering everything... but I digress. Beyond the equalizer adjustment, you also have so much control over the noise cancelling settings. When I'm at work, I can not only turn off ANC altogether, but I can adjust how much of the outside world is boosted. I have to be attentive to my coworkers and notifications on my computer, so it's amazing to be able to hear everything so clearly and still be able to hear the music in such amazing detail. I cannot say anything negative about this. $300 is a lot to spend on earbuds, so that may be one aspect of this that some would find as a negative, but this is probably the last set of earbuds I'll buy for a VERY long time, so that's one way I justify the price. The other is that you really get what you pay for here. Multiple professional reviewers list this as the best overall option for 2025, and they have done that with good reason. If you are on the fence like I was, and you can afford the premium price tag, I think you'll be beyond satisfied with your purchase.

These earbuds are SOOO close to being perfect it drives me crazy. I'm coming from the AZ-80s and most of the features are improved (but not all). Depending on your needs, my issues may or may not be relevant to you so let me break it down for you: Things I Love 1) Transparent Mode & External Mics - these things are AMAZING! They work so good! I was especially impressed when I used them at a concert recently. The measure sound volume at the concert was 100-106db. I poped in the earbuds and set the mode to 14% transparent. The sound was GREAT and the volume level perfect. I tried the same with the AZ-80 but loud environments would override those mics. Not with these. The only time I've had a the external mic flake out is when I was weed-whacking and the string hit some metal siding. Honestly - super impressive! 2) Sound Quality - I have very high standards when it comes to quality SQL. I've used these with many devices including an iBasso DX170 in LDAC mode and my phone. The sound detail is amazing. Hearing things in the music I dont typically hear with a pair of earbuds. Yes, the SQ is really that much better than the AZ-80. 3) Phone Call Quality - Again, compared with the AZ-80, these are WAY better. I regularly take calls in my car and half of the year my convertible top is down. I've been able to have 20min plus conversations at highway speeds with the top down with the other party saying they could barely hear the road noise at all. Well done! Mixed Feelings 1) Size and Shape - while I appreciate the smaller size of the AZ100 earbuds compared to the AZ80, they are a little more difficult to grab. They are more rounded and you have to be a little more intentional about getting a firm grip on them. Once they're in your ears, its a better more streamlined fit but you need to be a little slower and more careful moving them around. 2) Noise Cancellation - when wearing them around home or out on a walk, noise cancellation works great. They seems to have some issues though maintaining the noise cancellation mode on airplanes. I've had the pleasure of testing them on a number of different flights recently and while everything starts off well, after 20-40 mins or so the noise cancelling will start to whoosh out and then back in. It might be something about the white noise of the airplane engines. To fix it, you have to open the app, turn noise cancelling off then back on. I've had this happen more than 25 times on a one hour flight. 2) Battery Life - my fist set of earbuds had a battery drain issue. The left earbud would drain the entire pack just when sitting in the case not being used. Left me with a dead set within less than 24 hours of storage. The set was replaced under warranty and the 2nd set is working as advertised. The warranty process was a little bumpy - more on that below. 3) Warranty - unfortunately I had the opportunity to try out the manufacturer warranty process due to a batter drain issue. Contacting and communicating with support was pretty good - they were responsive and helpful. The only challenge was that the replacement set came back to me in Silver when I returned a set of Black earbuds. When I inquired as to the incorrect color and how I could be sent the same color that had failed, I was pretty much told - too bad. You get what you get. Kind of sucks considering I ordered the color I wanted, they failed in less than 2 months and how I have a functional set ... except for the weird color. A small detail I know but it would have been better if support had notified my first rather than surprising me and then denying my request for the right color. I hope you mileage will vary. Things I Don't Love 1) App Responsiveness & Reliability - in general the App works well once its open and successfully connected. Unfortunately I've had way too many times where the app cannot find the earbuds even when I'm playing music through them and Bluetooth shows connected. I just kill the App and restart but its really flaky. Even the initial load and connection of the app takes annoying longer than I'd like - especially when I'm only trying to change the transparency level or some other basic setting. 2) Touch Responsiveness - switching the earbuds on/off when I'm at home or in a setting where I need to hear a PA announcement (ie. airport) seems to take a little while to register. I know I'm being a little picky but earbuds block you out of the world around you. It should be quick and easy to return your focus to the world around you as needed. Just takes a but longer to register the press and mute the earbuds than is helpful. Many times the announcement was over or I would have missed most of the question by the time I got the earbuds muted. Could be quicker/easier.

These Technics Hi-Fi wireless earbuds are fantastic, especially for calls. The noise-canceling technology does an excellent job of silencing background noise, making my voice come through clearly even in busy or loud environments. Sound quality is crisp and balanced, and the earbuds are comfortable to wear for extended periods. Connectivity has been reliable, and they feel well-built and premium. If you take calls on the go and need earbuds that truly reduce background noise, these are an excellent choice. Highly recommend.

I bought this because my over-the-ear cans were too bulky when I was out and about town, and my other set of earbuds did not cancel ambient noise on my side when I was on calls. The over-the-ears I will be comparing them to are my Sennheiser BT450s, and my Bose NC700, and the TWS in my comparison are my B&W Pi8's, though I will mention my experience with Sony WF1000M3 that I used to own and a recent LG TWS. What I discovered in half a week of using my Technics AZ100's is that they are surprisingly good earbuds for a reason I didn't consider previously. Drivers and EQ I have experienced with a few headphones, TWS or otherwise, a hiss. The headphones would cancel noise well enough when there is noise, but when there isn't or during quiet moments in a video, there would be a hiss. The AZ100 doesn't have a hiss that I have been able to detect. Above that, the app offers the most precise EQ of all of my devices. Most just offer three frequency ranges, Bass, Mid, and Highs. This app offers seven, eight? The SoundGuys website commented the factory tuning is clumsy and bass heavy. If you take the time with these equalizers, you can get closer to the ideal EQ settings than if you only had three bars to adjust. I would say these drivers produce sound that is equal to any Sennheiser I have used. Out of the box, they sound like my Bose NC700 with punchier percussions -- which is really nice. These are more capable drivers than Sony's and LG's in-ears. I haven't gotten them to sound as good as my BW Pi8, but I'm being picky and the Pi8 are 33% more expensive. Call Quality The only weakness of my Pi8 is that it lets in too much ambient noise when I'm on a call. One time, I was doing the dishes and the AC was blowing, and my mother, who is hard of hearing, was able to call out every one of my activities. I guess it is a way to make the other party feel like they're right there with you, but I don't think that's what most people mean when they say that. I repeated the same test with the AZ100 and my mother could not tell when I turned on the tap or stopped it, when the AC kicked in or stopped, or when I was next to my audible dishwasher. The complaint from mom was that my voice sounded robotic and occasionally I'd sound farther away. The other party on the other end was easy to hear for me. This was not anything that was a weakness of any of my earphones, but I believe with the AZ100, their voice is processed via the EQ. ANC. The Pi8's ANC design is quite nice in that, around the office or at a restaurant, it lets in some of the ambient sound but doesn't let it interfere with what I'm listening to. I hear my environment, so I don't miss my colleague asking for my attention or my server approaching. I hear things but I don't, if that makes sense. The reason I mention that is that the AZ100 doesn't seem to be so well tuned in that regard. At a restaurant playing loud music, it is fainter, but my podcast is still competing against it. At the same time, in the office, faint sounds drop off into near silence but louder sounds don't seem to be affected. At its best, the AZ100 perform as well as my Bose NC700 or the Sony WF1000M3, but I feel this isn't going to be one of its best traits. It's still very good, mind you -- I'm pitting it against class leading cans of the last few years after all -- but if this is something that is very important to you above all else, then it's probably not the best TWS for you. Portability and Touch Controls The case is tiny. I alternate between these and my Pi8 on the weekdays. I carry both in my pocket. This case is smaller, lighter. I did not perform a drop test, because they're new and they're expensive. I did perform drop tests by accident on my Pi8's. Both the case and buds were dropped from hip height and ear height onto tile with no apparent scuffs to the plastic shell or the internal electronics. The touch controls of the AZ100 are more responsive, it felt. The Surprise The AZ100 went in a different direction than the other buds in one major way. They are extremely light. They are lighter than any of the buds I have ever worn. This has a surprising effect. The buds stay very stable in the ear. I can turn my head quickly, and they won't go flying out. I can walk around, and there isn't even the slightest bit of movement. (In my review of the Sony WF1000M3, I commented that they were so heavy and jutted out so much that once, when I was crossing a street and hurried just a little at the end, the buds fell and I was lucky enough to catch them.) Something like that probably won't happen with these, though, once again, I won't be repeating that experiment. These are a compelling entry into the TWS field. If these were released the same time as the WF1000M3, these are probably better in every category except for the ANC tunings. These are better than the LGs, but the LG's offer a UV self-cleaning feature. And the AZ100 can compete directly against many of the higher-end over-the-ear headphones.

For reference, I had a pair of Sennheiser Momentum 4 True Wireless Earbuds for months, so I have a pretty good reference point to draw upon for the reasons why I love these earbuds so much. I will be comparing the two because the class they're in is pretty much the same, and it's also my only pair I can draw a reference from :P - Comfort & Stability The ear tips are by no means flimsy and are stuck on almost stubbornly, which is a great thing. Taking off the MW4 earbuds and wiping down the ear tips always runs the risk of the ear tips falling off due to how loosely they are affixed to the earbuds. Not these. They're very stable, very comfortable, and easy to use. - Functionality and Practicality The casing is small and very practical. While the build quality isn't utterly insane and not made of felt like the MW4 earbuds are, it's compact, and that matters a lot, because without that practicality and form factor, why even lay the premium for earbuds such as these? - Battery life This is by far my biggest selling point personally coming off of MW4 earbuds with regular daily usage. I love to leave earbuds in for extended periods of time to listen to music and tune out the world, doing my own thing, you know? These are the best in its class because of this. Not even the Pi8 Bower and Wilkins earbuds have as much battery life as these, and for a normal, regular, 8 hour shift five days a week? Yeah, it's no contest. I love these things. - Ease of use and App functionality Oh my goodness. The app. Mwah! I don't have to fiddle with sound profiles as needlessly as I do with the MW4, having to constantly tweak it depending on what I want out of my music. Hit the EQ tab, press on "Dynamic", and bam. Audio so damn clear that not even the MW4 Sennheiser signature sound can compete. AN UTTER WIN!

Great sound! Comfortable, nice bass, customizable sound based on what you want to hear. Waited till they went on sale. Maybe not the best "bargain" but best sounding and most stable of all. Works almost as good as the airpod pros in an apple environment. When at the gym they stay on great. I don't have the interference from other bluetooth devices near me. Very good noise canceling and good with phone calls. If you enjoy detailed music listening regardless of venue these are great. Good battery life. They do require some maintenance of the terminals and routine cleaning or may not charge well. I have owned Sennheiser momentum 4 (returned them as overrated). Liberty pro series. Apple pro 2. Liberty 4 pro (IMO) have best value but have problem with interference in crowded spaces from other bluetooth devices such as gym. This is great for watching some movies in Dolby atmos.
