Major improvement previous version

I am using the RMCE BT2 with Shure SE 846 earphones. I have had the previous version of the same product from Shure (the BT1) but was forced to carry both the cable and Bluetooth Connector as the sound quality was not up to the mark. With the latest re-incarnation of the product upgraded to Bluetooth 5, the sound quality has improved substantially. Even with high resolution audio (from Tidal ), I cannot tell the difference and stopped using the cables altogether (don't forget you have to use adaptors for connecting to most devices now with cables). Connectivity and integration with iPhone X/Xs is superb over BT. Despite Shure's claim of 10-hour battery life , it seems the real value is somewhere in the range between 6-8 hours with volume turned up. I have also noticed no degradation of sound quality over distances under 10 meters. Excellent product overall, great finish and ergonomics. Highly recommend if you have already invested in high-end Shure earphones.

Huge upgrade over the BT1

Let me start by saying that I was very disappointed with the BT1. I was excited at the prospect of being able to use my Shure monitors wirelessly on my daily subway commute, or to pair them to a device and listen while walking around at home without having to be tethered to anything. I knew Bluetooth wouldn't give me the same fidelity as a wired solution, of course, but was willing to sacrifice some quality in favor of convenience - especially since I could always go back (oh, the joy of MMCX connectors) to using a cable for more "serious" listening / work whenever I needed to. But the BT1 really just didn't cut it: poor audio quality, very high noise floor, audio dropouts and poor connectivity, weak battery life, and poor cable design (i.e., not comfortable to wear). I used the BT1 for about a week and then went back to using cables again - it just wasn't worth it. I was pretty hesitant to try Bluetooth again but decided to give the BT2 a shot after reading some positive reviews. In short, I'm very glad I did. Shure fixed virtually all the issues I had with the BT1. The BT2 has great quality, great battery life (I average ~10-12 hrs use between charges), almost no connection dropouts, and - thanks to the pendant/clip design - is very comfortable to wear. I've been using it almost every day with my SE846 monitors and have had almost no issues at all. It's still Bluetooth, obviously, and you can definitely hear that - but it's much, much easier to forget that you're connected wirelessly. The biggest improvement (for me at least) is that the noise floor is much lower - almost unnoticeable unless you're in a very quiet environment. In fact, I often have to check to see whether the status light is blinking in order to see if they're powered on or not (something I never had to do with the BT1 - you could hear the hissing). They're not perfect. In particular, the microphone seems to be pretty poor. I haven't had good success using the headset for calls, but that's also not what I bought this for. Also it's pretty pricey at the moment. But overall, strong recommend if you're looking at a wireless solution for your Shure monitors - you can't get much better than this. Edit: forgot to mention one of my favorite features! These can be paired with multiple sources simultaneously and the device will reconnect automatically when those devices are within range. Super convenient to be connected, e.g., to my phone and laptop at the same time and not have to switch sources constantly.

Better than the BT1

I have been using this for about a month now. There is a slight difference in audio quality over the BT1, but I am using SE215 earbuds, so the difference may be more noticeable on higher end earbuds. Advantages over BT1: Much longer battery life (I can easily get 8 hours of constant playback, and 12 isn't unusual). Better Bluetooth connectivity, especially to multiple devices (it won't playback from multiple devices, as far as I can tell, but if you have 2 devices connected, and 1 is already playing sound, it won't switch to the other if it starts playing, which is a nice feature) Slightly higher quality audio Much better clip. The BT1 uses a plastic clip that broke after a couple months. This one uses a metal clip directly attached to the body, which seems less likely to break Disadvantages relative to BT1 Price. The BT1 is a bit overpriced relative to other mmcx bluetooth adapters, this is maybe the most expensive one out there. I like the form factor, but may not be worth the $50 compared to the Westone adapter

Outstanding Accessory for Shure In Ear Monitors!

I recently decided to replace the stock cables that came with my SE 535s. I bought all three available cables from Shure to compare them. Each of these cables are well made and sound fantastic. I tried: Shure RMCE-BT2 High-Resolution Bluetooth 5.0 Communication Cable $149 Shure RMCE-UNI Universal Communication Cable for Detachable SE Sound Isolating Earphones. $29 Shure EAC46BKS 46-Inch Black Detachable Earphone Cable $35 The EAC 46BKS cable does not have an inline mic/volume control. and it doesn’t sound any better than the RMCE. The RMCE is cheaper, sounds just as good and is more functional. The clear winner. The RMCE BT2 is wireless, which is great. The sound personality or signature is similar to the wired option but as you might expect, the high end and low end of the dynamic range is less present. (Do to the required compression involved in the Bluetooth transmission) The overall sound is pleasing and balanced but the upper transients and the lower thump of the bass is quieted a little. Also the sensitivity of the drivers is decreased a bit. At maximum volume, the sound level for loud critical listening is achieved. With the wired connection, you cant turn it up beyond 3/4 without it becoming painful. When walking around with the wireless set up, the playback volume is more than sufficient. There is a nice clean presentation of the sound overall. Having both options is great, depending on the circumstance. The wireless option is excellent if you don’t want a cord in the way. But when you want maximum playback dynamics you can choose to the wired solution. Yes it’s luxurious to own both, but so is owning the SE 535s. :) Im extremely happy with the two options. I highly recommend them both.

Much needed upgrade!

This is a much needed upgrade over the BT1. I currently use the Shure BT2 with the Campfire Andromeda. Here are my findings. Quieter amp section. The BT1 was a hissy mess. Battery life is 2-4 hours longer. Voice commands are no longer ear piercingly loud. Support for more codecs such as AptX, AptX HD, AptX LL and AAC yields better sound. Amp output impedance is now quite low as my Andromeda’s no longer sound a tad treble heavy as it did on the BT1. The unit that holds the electronics has a firm metal clip that alleviates the weight of the cable. No latency when watching videos thanks to BT version 5 and Aptx LL. Support for AAC when I use my iOS devices and Apple Music resulting in a 1:1 transfer with no further transcoding. Beautiful sound in summary and much easier to use. Thanks Shure!

Finally an audiophile-grade bluetooth cable

This is an excellent iteration on the previous model. I own a pair of SE532 s and up until now you can only reproduce their entire dynamic range with wired cables- rhe shute BT1 audibly muddied them. The BT2 is great- Shure has finally made a high quality bluetooth receiver that is worthy of their high-end monitors-very happy with the purchase!

With Amphenol MMCX Jack to Jack RF adapters works with other headphones

I have SE215s and wanted to have an HD bluetooth receiver that works with my Audio Technica ANC9s as well, and figured it might work if I used the fact that I can reverse the cable with MMCX with adapters and plug it into my ANC9s, which I also use on flights. They sound amazing, but if you use the Android cable that has the single button on it, be sure to tape the button always on because the location of the shield contact in the ANC9s is not positioned for a TRRS 1/8 inch phono plug, but TRS only. I just needed to buy Amphenol MMCX Jack to Jack RF adapters from Mouser or any other location to get the gender bent around to get the hack to work. On the SE215s the bluetooth sounds amazing, so I wanted to try it on something more substantial, and it does work, even with the ANC noise canceling switch on (I got these because they work with a dead battery too, and don't require active mode unless I want deep bass and active EQ -- the EQ I can also get from my bluetooth player (Samsung S8 active)).

At long last!

They finally figured it out. The sound and battery life is awesome, feels relatively solid too. I imagine version 3 will be a bit smaller and have replaceable cables (for when the battery eventually dies). I thought the hanging battery would bother me but the clothes clip makes it a non-issue and it is worth it to finally have a good wireless solution for my Shure SE846's.

EDIT: This is Exactly What I Hoped For

My original review placed this device at a one star and my initial experience with it was that it was entirely unusable, disconnecting every ten seconds from my Google Pixel. I had tried factory resets, re-pairing, disabling HD audio, etc. I ultimately determined this to be an issue with my device, as I paired it with another device and it worked great. I'm not entirely sure what the issue was underneath, but it seems like the specific place at that specific time was receiving a lot of interference from something, which is disquieting. However, it's pretty clear now that this device IS the device I was hoping it would be. 8-10 hours of battery life, it's comfortable with SE215s to sleep in, and it's amazing. I can't recommend it enough. My cabled SE215s were great but I was constantly getting them tangled in seat belts and on random objects as I moved around. The microphone quality also seems to be pretty good, as I had one conversation and no complaints. I have not attempted to pair it to multiple devices as I'm not sure if this is supported or not. Absolutely worth the money. The only concern I have is the "memory band" on each end of the cable getting broken, which was a recurring theme and I had to purchase new cables every 2 months or so. I bought a warranty on these, so if the memory band breaks, I'll hopefully be able to get it repaired/replaced/exchanged.

Amazing product!

Since I bought the Bose qc35, I've been stopped using any wired headphone. Even though I have a great pair of Shure SE535, it has been placed in my drawer for a really long time. The other day when I saw Shure RMCE-BT2 got the bluetooth 5.0, I purchased it with no doubt. And it turns out I was right. It sounds so good, no latency for videos, really easy to control, and most importantly it bring my SE535 back to life.
