The listing doesn't give the entire details of the "Cable's" features. But I went with it just for the AptX-HD tag. To my pleasant surprise, it does have dual device pairing and it works perfectly between 2 phones. If one gets a call, the media stops on the other phone and continues to play after the call is over, only if the screen is on for videos. This is precisely what I wanted.
But the drawback is also pretty significant which is the build quality:
The buttons, OMG the buttons! They're harder to press than any button I've ever had to press before. I mean if you've ever owned a Bluedio Bluetooth dongle from back in the day, it's harder than those! And those were pretty hard already.
Secondly, a wireless cable, are you kidding me? Realme's flexible neckband is the obvious choice here, please implement it otherwise it's a huge hassle to manage this thing! Those 2 buoys on the cable do not make for a hassle free listening experience! But on the other hand, you barely notice these are on you because it's so light. I have used them all day, learnt how to live with the shifting cable for now. I'll probably use one of my old Bluetooth neckbands to stabilize this.
Now sound quality: There is a slight shift to the treble side as compared to a physical cable, other than that it's pretty much the same though it's giving slightly different outputs with different devices. With my Samsung TV, it sounds exactly like it should but with the phone that doesn't have AptX-HD, the treble shift is more prominent. It obviously performs the best with the phone that has AptX-HD.
The mic is basically an after thought, it works just fine but you have to hold one of the buoys' up to your mouth for better clarity if required.
Overall I'm enjoying the performance even though it's a bit of a hassle to use.
Hi Indranil Guha,
We are so happy you took out time & elaborately reviewed the product with a comparison. We are sure this will help our customers to make an even better & informed decision.
Yeah, its packed with Bluetooth 5.0 that offers a great connectivity and enables the IEM to connect with two devices but if one device is playing then the second device wont be able to override, which I think could be a great function (Well we've that in JBLs) but... huh!
Also as it is written that the mic is noise cancelling one and blah blah blah..., but in my case the person on the other side is unable to hear until I hold the mic near to my lips, like if I'm about to sing... lamao, just kidding but I'm not comfortable with having calls with this.
And here comes a chef's kiss to the battery backup. its awesome, almost 8-9 hours on a single charge, it might be variable on per person usages.
Now when comes to powering up the 8 drivers in my ZAS, it works flawlessly.
It could be much more lovable if they could provide with type C instead of type B, yes it have micro B for charging purposes.
I have divided my review into two sections:
1. Good mic and sound quality (for comparison with wired pairing look at the 'Cons' section)
2. Good battery backup - I ordered this because I am an audiophile and also I have work-from-home requirements. So, with around 2-3 hours of music and work-from-home connectivity to Microsoft Teams, this product will be able to last for 2 odd days. This is 2nd day I am using it (with very moderate use like 3-3.5 hours of calling, 3 hours of music, and rest is standby time).
3. Very fast dual connectivity - It automatically connects to 2 devices (last paired) within 1-2 seconds of powering on. The software prefers mobile phone over laptop. So, if you recieve a call on phone and laptop both, it gives preference to mobile phone at a time. however, automatic switiching is amazing when the call is disconnected.
1. Sound staging and separation are not the same as compared with the wired connectivity. Wired pairing offers you around 20-22% better clarity (with bass clarity), sound staging, and sound separation. However, for daily working lifestyle, you will adjust to it without much noticing within a day or two of use.
2. Buttons are too tight.
3. Microphone Clarity - The collar band when worn from the front side i.e., wire hanging in your chest area, the voice transmission is 'crystal clear'. However, when worn around the neck (usual back side) then the 'clarity is not good'. The other person always complained about me not being audible, due to which I had to hold the mic close to my mouth.
