Shure True Wireless Adapter Gen 2 - Bluetooth 5 Wireless Earbuds with Secure Over-Ear Fit, Sound Isolation, Long Battery Life & Charging Case - Perfect for Gym, Running, Travel & Work Calls

Weird title, but it does change depending on the iems you have. I used these with shures se 215 (mainly) and aonic 3s and the adapters dont change the sound (without eq), they make them more convenient to use iems. And at sub 200 dollars, these really do look like a big investment, but the features make the price look more reasonable.•Design + Comfort: These adapters are shaped pretty aggresively on the ear hook since shure assumes you'd use it with only their products or others using shures style of iems. Of course you can plug in any iem into these, as long as it uses an mmcx connector, anything else like 2 pins are gonna need an adapter to use these adapters. When using adapters (right angled or straight) with these on iems like the moondrop blessing 2 or Shuoer s12s, would change the comfort of these adapters and make it feel more unnatural and uncomfortable to use. And with the weight of the controls resting in any other area of my ear that wasnt designed to be rested on in the first place, would make these painful to use after an hour or two in those cases.•Controls + Features: The controls are simple: single, double and triple button presses to do whatever you want, which will always be superior over touch controls. What helps make these adapters more unique (aside from them being true wireless) and superior over most true wireless iems is the environment mode thats included with these things (that have the ambient mode included). In the app, you can adjust how loud/quiet you want the environment to be so you can hear your surroundings better and the clarity of this feature is great, compared to tws buds like sonys xm3s, sp 700ns, cleers ally plus II's (which wasn't CLEER at all and was more like just noise cancelling being turned off and a muffled attempt of ambient noise added in) and felt on par with apples airpods pros and boses quietcomfort tws buds. Also in the app is an optional feature they call "PausePlus", which turns on the environment mode when pausing your chosen content to be aware of your surroundings, and turning it off when you press play only on the adapters. And this makes sense as how could the adapters know when to turn the environment mode on/off when you tap pause/ resume on your device. But an issue I have with the environment mode is that when someone is talking to me, it was harder for me to hear their voice over the surroundings. And wind noise makes it impossible to hear anything unless you can read their lips.•Connectivity + Charging: With the nature of these adapters being wireless, they use bluetooth to connect to whatever device you choose and magnetically connect to the case whenever these are dead/ low on battery and need charging, or simply not needed. Also a neat little inclusion of a battery indicator on the back of the case. And here comes the problem with these adapters and the case design. My specific adapters are cranky when they get dirty due to the nature of my job being drywall. And the contact points for charging that's on the case demand that these adapters to be clean in order to charge them and be put away. If not, the light still turns on red to say they're charging, 2-5 seconds later, it turns off, then the light comes back on for 2-5 seconds, rinse and repeat. And either both or one of the adapters will be dead once you take these out to use them, unless you wipe both the connectors on the case and contact points on the adapters clean to charge properly.•App: Of course being wireless, these come with an app. But before you can actually use the app, you are greeted with shure asking for your data, which is completely unnecessary in my opinion. Once you innevitably tap the check box to not send them data (or keep checked, idk, humans are weird), then you can explore the app. The adapters would like to be updated but works fine without it. There is the previously mentioned environment mode and PausePlus gimmick right when you have specifically both adapters connected. Once you have only one or none of them connected, you cant do anything. Theres also an equalizer setting to "fix" the sound of your iems and a settings tab to mess around with. This is where you can customize your controls, update the adapters along with being able to turn off the certain voice prompts the things yells out. Which I think should be a necessary option if anything bluetooth audio related has voice prompts since the voice just wastes time.•Sound: I already stated that it doesnt change the sound of your iems without any eq, but there is a small bit of latency/delay when watching videos, but the audio does eventually sync up after a few seconds of video playback.•Finally: TL;DR they work great, scary price tag, but I would recommend this if you are looking for a pair of tws adapters for your shure/ mmcx compatible iems.The Shure RMCE-TW2 Bluetooth adapter(s) represent the pinnacle of Shure's efforts to create a wireless solution for their SE line of earphones. They address nearly all of the limitations of previous designs, most of which I have owned and used extensively, and add new capabilities which significantly increase the quality of the experience when using them. In fact, I would say that these are finally a Shure Bluetooth adapter worthy of the SE846 earphones to which they are attached.To provide a context for the many improvements made to the TW2, I will be comparing it to Shure’s previous BT1 and BT2 adapters with which I have extensive experience. It’s worth noting that the TW2 is a second generation product that looks identical to the first gen TW1, a product that was so plagued with operational issues and design limitations that I never bothered to test it out. Do not inadvertently purchase the TW1.Shure’s original BT1 Bluetooth adapter was just okay. It didn’t drive the SE846s to particularly high volumes, the battery didn’t last particularly long, and connection strength was weak. I eventually replaced the BT1 with the upgraded BT2, which had a better design and offered better battery life and more output. It was a good product but not perfect. Like the BT1, the BT2 would temporarily drop the connection to my iPhone at particular locations in my home or at my office—walking through the man door of my garage, for example. And if I put my iPhone in my front left pants pocket and twisted my body the opposite direction, the audio would temporarily drop out. This made raking the lawn a particularly annoying experience. I’m happy to report that the TW2s have resolved these issues completely. The Bluetooth connection has remained rock solid from the first time I turned them on; I’ve never experienced a single dropout. In fact, the range is so good that I can set my iPhone down and walk off to other parts of my home without experiencing any deterioration of the connection at all. And the sound output of these adapters is quite good.Much of my time listening to my SE846s occurs while I’m outside working on projects, doing landscaping maintenance, or snowblowing. While both the BT1 and BT2 were far more convenient than using a cord plugged into my iPhone, they both still presented a cord dangling from my neck which would inevitably get caught on something and rip an earphone out of my ear. The lack of cords on the TW2s completely eliminates this issue. Before trying them, I was a little concerned about the comfort of the new design. Would having the weight of two batteries behind my ears be annoying? As it turns out, I can hardly even tell I’m wearing them.A related area of improvement is the ability to operate the TW2s while wearing gloves. With both the BT1 and BT2, the controls dangled from the cord. Locating them while wearing gloves was a challenge. Pressing the tiny buttons was difficult if not impossible. The single large button on each of the TW2s is much easier to locate and press. (Not always easy but always easier.) And because the TW2s have built-in mics, I no longer have to stop what I’m doing, take off my gloves, and remove an earphone when my wife has a quick question. I can simply press the large button on either of the TW2s with my gloved finger and the built-in mics pause what I’m listening to and amplify her voice. This situation was such a pain point with the previous designs that this feature alone justifies the cost of the TW2s for me.The TW2s offer other advantages as well. Shure offers a very useful app that can update the TW2 firmware and load precision, customizable 4-band parametric EQ curves tailored specifically to the capabilities of your particular SE earphone model. (Some users may have noticed that I have yet to mention sound quality. The TW2s do seem to be at least a small step forward in this regard—they certainly aren't a step backward—but any really noticeable difference comes from tweaks to the parametric EQ in Shure’s PLAY app, something that wasn’t possible with the BT2.) The app also permits the customization of controls and prompts, a hugely useful capability that was absent from previous designs. And charging is wireless now. No more fiddling with a USB Micro-B cable—though this does mean that you must carry the somewhat large charging/storage case with you when you want to charge the TW2s.Finally, the phone experience. I don’t spend much time on phone calls but the experience has been excellent. The TW1, the gen 1 version of this product, was widely dinged because phone calls only came to one ear. That limitation is now gone. You can hear your caller in both ears. And my wife tells me the mic quality is excellent.With all of the improvements, there is very little that I feel the TW2 could do better. My only minor complaint relates to the lack of a battery status indicator. To be clear, I have yet to run into a battery life limitation. The TW2s seem to have excellent stamina. But there’s no simple way to tell how close I have come to exhausting them. The older BT1 and BT2 would announce the remaining battery life whenever they were powered up. “Eight hours remaining.” This was great. I always knew how long I had at the beginning of every listening session. That feature is gone. The only real way to know where you are in terms of capacity is to open the app and look at the tiny battery indicator which provides a percentage remaining but does not translate this into listening time.The bottom line is that I am absolutely delighted by my upgrade to the TW2 and recommend them to anyone using compatible Shure earphones. They’re awfully close to perfect and easily worth the price of admission.I wasn't Shure how I'd like IEMs, so I bought the reasonably priced wired SE215s. They were so comfortable, I took the plunge and bought the Aonic TW2 kit. Match made in heaven.I love the battery powered puck design. The thing I always hated about wireless earbuds of most designs, was that every time I grabbed them they were dead or near dead because I forgot to charge them. Replacing the TW2 SE215 combo back in the puck after use means they're always ready to go. I've heard other users complain about the size of the case. But since I'm an old dude who never wears skinny pants, they go with me everywhere in the pocket of my cargo pants.Great for taking calls on the go, or listening to your digital media collection. The environment mode is genius!!! These are the only earbuds I will wear in public.I brought my original wired earphones several years ago. I upgraded to the S1 Bluetooth then the S2 and now these which have no wire at all. They are really good. Obviously the actual speakers are the same but having no wire and in case charging so they are ready for the next listen. The only down side is a slightly larger case but being clipped in makes them much more secure. The Bluetooth 5 enables me to walk from room to room leaving my phone several meters away without loss of signal.I tried the Shure 846 and SE535 with the Gen 1 wireless adapters and compared to a wired connection the sound was flat and lacking depth. I'm no audiophile but the difference was simply so great it wasn't worth the money. I almost purchased a set of Powerbeats Pro for running but thought I'd take a chance and try the new Gen 2. I can't immediately tell the difference between wired and wireless and I'm delighted I tried Shure again.The case looks like the Gen 1 and until I paired the adapters and they identified as Gen 2 it wasn't clear that I hadn't been sent a set of Gen 1 by mistake.I own a pair of Shure SE846 and they are for me, the most comfortable wearing and best sounding earphones I've experienced. They deliver a warmth and clarity of sound, and with the interchangeable filters to adjust the tonal balance are genius.Having read about the Shure True Wireless (Gen 2) Adapter, I thought i would have the best of both worlds by having that same aural experience but without the cables. I do acknowledge that wired systems will always (for now) have better sound texture and fidelity over wireless, but using the Shure Play companion app - configuring it to use the SE846's and tweaking the EQ as best as I could, the sound experience was abysmal. I played a variety of music but consistently experience distorted treble, poor bass, and flat midranges.I contacted Shure customer support who requested that I send the adapters in but wanted to charge a minimum of £50 just to look at them.I am frustrated and genuinely at a loss with what to do with these adaptors, so for now I'm back using the wired connection.I brought these as part of a package with some Shure Aonic 4 earphonesThey are an interesting addition to the earphones and, once you get used to taking the headphones on and off, very easy to use. There is a noticeable loss in the sound quality, but that is common with Bluetooth streaming. I’ve not noticed any dropping out of the signal.Comfort wise as they fit over the back of the ear I am more ware of them than the true-wireless I am used to. Controls are easy to find and use.An interesting addition to my in ear monitorsThis headset is rather uncomfortable, especially for people who wearing glasses. The connection wire is too thick comparing to normal cables. Is also very difficult to put on or take off. Charging kit is hard to place the earpieces. There seem to be a lot of unconsidered design issues...The sound has usual static sound when no music/sound is played. Sound quality wise is ok, but I get headaches after using this with a set of SE535 within only 10 minutes testing. I have had so many wireless headset (cheap/bad/good/expensive ones), this is the first time I experience headaches.If you really need a wireless solution for beloved mcxx ear piece, maybe consider FIIO UTWS5...
