MEE audio - CMB-BAL-SET, Universal MMCX Headphone cable with 2.5 mm balanced terminiator, with a 3.5 balanced, 4.4 balanced, 3.5 stereo- Gunmetal

In summary the btx 1 failed after 40 days. Do not Buy!Pros- comfortable to wear.- pretty good sound quality- bluetooth range is good- easy to pairCons- btx 1 failed after just 40 days. Outside of the return window with Amazon. Looking into the warranty process.- battery life is poor maybe 4 hours at best- charging port would be better if it was USB C.- MMCX connector is weak.

Los compré el lunes, llegaron a los 4 días. El sonido es claro y con un buen rango de alcance. La tecnología aptX permite que los 4 drivers de mis W40 de Westone desplieguen un amplio espectro de frecuencias, no al nivel de un cable balanceado, pero si con una excelente calidad de sonido. La potencia es suficiente para a partir del 80% empezar a distorsionar un poco, pero difícilmente tendrías que usar el volumen arriba de ese límite. Ampliamente recomendados.

Bought it to replace stock cable from Mee audio pinnacle p1, wanted to try this iem from balanced out of my fiio q5. Compare to stock cable this one has slightly more bass and slightly less treble, difference is very small but noticeable if you prefer analytical listening. Comparison was done using 3.5mm out of my Q5. Overall, it is excellent cable in terms of build and sound quality.

First, I want to let you know that I was given a BTX2 by Meelectronics for my review. I owned the BTX1, and I can give a comparison, and they trust I will give a honest appraisal. Second, I own a Pinnacle P1-probably the best earbuds for the money. Finally, I use my bluetooth adapter full-time. I have a great cable, but they just seem so inconvenient now-unless I know I won't need portability.Now, to begin, the delivery of my new BTX2 was quick. When they arrived, It was packed well, and it had similar packaging as the first generation. Even before they arrived, I got an email with a link to directions in case I could not figure out how to use it. The link is: https://www.meeaudio.com/content/usermanuals/UserManual_BTX2.pdf. This is a new feature of their customer service.First ImpressionsThe BTX2 feels solid. It is made of great quality components. Compared to the first generation, the wires are thicker, the battery and the control modules are bigger, and the cable length adjuster works better than the first generation. It is an "S" retainer that securely holds both sides of the wires rather than the old clip-type that came off all the time and I was surprised I did not lose.The control module had the familiar three buttons design, but it was different. The BTX1 buttons has three separate buttons. The BTX2s has one button, but it has the three buttons embedded underneath with tactile ridges to indicate where the buttons were. You have to learn to feel the buttons, but it did not take much to get used to them. I suspect that it was better at making the adapter resist any moisture.It was easy to connect the BTX2 to my Pinnacle P1. The BTX1 has tight fitting MMCX connectors and was difficult to separate from my Pinnacle P1 (an understatement), but the BTX2 has great connectors. I easily connected and disconnected them over and over again. Right buds are on the side of the control unit and the left is the battery side.Pairing the BTX2 was just as easy as the first generation. Press and hold the Multifunction button for about 4 seconds until you hear the headset say “Pairing” and the light flashes red and blue. The voice is softer than the first generation, but the communication is the same. The BTX2 talks to you in a soft and gentle (female) voice to let you know what is going on. Powering on, powering off, connected, disconnected are spoken into your ear. The ease of use of these were a dream. Automatic connecting to my Mac and my phone simultaneously allowed me to answer the phone, switch effortlessly between both sources, etc. They are just that good and easy to use. Sometimes I had to contend with the computer, but that was rare. When connecting and playing music, the music would fade in rather than connect full volume. It was a nice touch, and, no, the sound settings were not set up that way. This is part of the BTX2 set up.Connection never dropped and the distance from the source was as good, if not better than the BTX1. Unlike the BTX1 which required reconnecting when I got too far from the source, the BTX2 would automatically reconnect and fade in what I was playing. Very nice touch.ChargingA short charging connector is included with the BTX2, but you can use any standard mini-usb cable. The charging port is covered by a "hinged" soft plastic cover. In the BTX1. I thought that the cover might break off over time with wear and tear, but that never happened. This one is a kind of hinged cover that is more flexible and should not break either. Nice design. One other difference is the LED light. When it is red, it is charging. When it is blue, it is charged. In the BTX1, these lights were bright. In the BTX2 I have, these lights are softer.SoundThese are connected to my Pinnacle P1, and so one would expect the sound to be wonderful. I was not disappointed. The sound was spectacular. I think the output of these are a bit more than the BTX1. It was easy to turn them up to a point where I really did not want any more, but it depends on the source.Then I started to play around with the codec. Understand, before I played with the codec, the performance of the BTX2 would please anyone-even using the standard SBC codec. A common opinion is that AAC produces higher quality, and some believe that AptX is even better. Some think that there is not much difference between the two. It is up to you to decide.I wanted to check out the AAC and AptX for myself to see if there was a difference in sound. I checked the codec being used on my MacBook Pro and it was using SBC. I turned on the AAC in my MacBook Pro and I think there was big difference. Why AAC is not a default setting, I do not know. It may be Catalina. I forced my MacBook Pro to use the AptX codec, but I am still working out how to get the system software to use the AptX. I am not sure why the AptX is not kicking in, but I am sure it is because of the software and not because of the BTX2. Still, the AAC quality is excellent. A recent update to system software, and Apple turned on the AptX, and it stays on for every type of media. All I can say is, “wow!” The sound is magnificent. Try watching Apple TV+. The soundtrack is amazing.When I used the BTX2 with my phone, there was none of the issues as with my laptop. There is a way of testing what codec it is using, but Apple will not let me read it. I will update this review when I find out. But I do not know how much I would gain. The music is nothing short of spectacular which makes me think that it is using AAC natively. The separation is excellent, creating a spacious sound stage. Movies sound equally great too. The volume for movies is not always as loud as I want, but I think that has to do with the import or video converter settings or the source. If you want more, make sure that the import volume is its highest. You can always turn it down. I dream of Dolby DTS and 3D sound in the future.Call features, Siri, microphone quality, and batteryJust like the BTX1, the call features and “hey Siri” work as expected. Having used single button systems and no button systems, the BTX2 is so much easier to use and navigate. You just have to get used to feeling the buttons.The microphone is still a weakness because it is so far away from the mouth. In quiet environments, the call quality is good. In loud environments, the person on the other end hears the background noise and my voice is not as differentiated. It helps when I cup the mic to my mouth so that it focuses my voice to the microphone. However, the background noise is still there. It would be nice to have noise canceling, but I suspect that the feature would considerably reduce the 9 hour playback time. And, yes, it lasts 9 hours.The battery is amazing, and it will tell you when the battery is low and powering down. I know. I ran the BTX2 for a full day before the soft voice came over the buds saying, “battery low.”One other thing I noticed was that the BTX2s will not shut off after a certain amount of time as the BTX1s. This is actually a good thing. I can keep them on for a long time and they will standby for a call or until I turn on some music or a movie. This does not seem to make a difference to the battery life.Final ThoughtsSo, the BTX2 gets 5 stars for its design, great quality, ease of use, and its great sound (Although, part of the great sound is due to my Pinnacle P1). In my BTX1 review, I thought the next step would be to go fully wireless, but this has its advantages-that being battery life, not having the hassle of two units pairing, and being able to hang the earbuds around my neck when I do not use them but want to have them available. The designers certainly learned from their first experience and put that learning into the BTX2.The BTX2 strong points are: its excellent build quality, its excellent sound quality, its solid connection quality, its ability to connect to two sources at the same time, and the designer’s attention to detail that make the BTX2 easy and a joy to use. I would also add that Meelectronics has excellent customer service. In all my experiences with them, they have always honored their warrantee and recalled any defective parts they have discovered to be a problem.The BTX2 weakness? I could only find one-the microphone. Though not at all terrible, it is certainly an area that could be improved upon. However, I believe that it is due to the limitations of iOS software and not the BTX2. In time, software may Improve the experience. The experience might be different for Android phones.If you have earbud headphones that use the MMCX connectors, and you want to go wireless, then these will take care of your needs. Enjoy!Update: it has not been a year and the BTX2 has failed. Not sure what went wrong. I still say that they are a solid choice. I think the battery failed, but I am not sure. Will buy another.

Item exactly as described.
