Bought to use with my KZ ZS10 Pro's in the gym because cables in the gym are annoying. No issues with connectivity (even with older Samsung phones) and sound quality is on par with cables. Battery life on mine is excellent and the build quality is good. Highly recommended!
KZ Apt-X HD
the bluetooth cable works good for a close distance.
I'm pleased with the high level of sound that it can transfer and the comfortability a bluetooth headset provides.
I also found a few things which could be more optimized -
1. the ear hooks are too big for me and fall out from my ears, I would suggest to make them in defferent sizes
2. the bluetooth doesnt reach to distances longer than 5 meters
3. the buttons are really hard to push and its difficult to work with
Works perfect. Very high value for the price.
Cable is a bit stiff and keeps its own shape.
Works well and connects quickly. If connected to two devices simultaneously (phone and pc), reluctantly switches from one to another. Also, if moved away from the pc, while connected to the phone, it beeps as if searching for another device, Unless switched off and on again the beep remains. Very stiff buttons. Has no function of FFW. Sound transmission is good when on HD. Connection MMCX plug needs bit of a force to plug into earphones
Sound quality is OK, but there is too much background noise for my taste - not a dead background and it ruins music quite a bit and tires the ears on podcasts. Awkwardly I found the sound amplitude and richness to be greater on the 2-pin set rather than the MMCX!? - There is an annoying loud voice when turn-on/turn-off. Fit is a little awkward with the long cable and no weights to hold it in place. Would have been better to place the remote/battery and Bluetooth receiver closer to the ear and attache a sliding cable collector to enable adjustment of cable length and fit. For workouts it flies all over the place. The ear hooks are finicky and could use some reinforcement/adjustability (however better on the MMCX than the 2-Pin system as the former can rotate adjusting the angle of the hook). All in all; much room for improvement. But; also not the most expensive option.
These are excellent for taking my 10driver IEMs on the go. However, 1) the Menu voice for Power on and Power off is inconsistent in volume. Far too loud.The connection notification beeps are also too loud. Perhaps the mindset was that you should power them up and verify the connection BEFORE putting them on and then take them off before powering down. 2)The connection to the pods aren't as robust as the wired cable that gives a satisfying snap. I believe I'll eventually lose one of my IEMS because of how loose the connection is. 3) The weight of the wire is not balanced. It could be better. I am glad I got these. Great value, Good sounding.
Low latency. It's good enough to watch video on. So far the only "perfect" wireless headphones I've seen are the H1 AirPods because MacOs and iOS will smartly delay video to sync with audio latency. These aren't perfect, but video is completely watchable and latency is lower than any BT 4.x headphone I've ever used.
Solid connection. The range is extremely low, but as long as the transmitting device is close, it doesn't drop or run out of buffer.
Controls are intuitive. This is often not the case for budget BT devices.
Connection is simple.
The cable is thick and ugly. They will make your beautiful earbuds look ugly.
The ear bend isn't sharp enough, so it juts out and doesn't sit right.
The cable is too long, so there is a lot of slack around my neck. A shortener loop would be appreciated.
They are charged via micro USB instead of USB-C.
There is a small background hiss like you get with loudspeakers driven by a poor quality amp. It's small enough that it's not a deal-breaker.
These have the lowest range of any BT headphones I've ever used. As long as you use them with your phone, it's not much of a problem because the connection is stable. Don't expect to be able to walk from room to room without your phone and have these still work.
I had a $20 Linsoul credit, so for $10, I'm really satisfied. For $30, they are ok. This isn't the ideal or perfect solution to make the MMCX earbuds you love wireless, but they do the job.
While I haven't used this very long and I am probably not as discerning as other reviewers who seem to expect this $30 Bluetooth adapter performs stellar, I found these to be very good products. It's true that there is a little hiss in the background but my $200 Sony Bluetooth earbuds have the same issue. Between that and the long cable, which is a bit longer than is desired and has no "shortener" loop, I haven't experienced any other issues, which is why I give it 4 out of 5 in this case. Perhaps I'm a bit happy because I expected these to be unusable when looking at other reviews but they are really not bad at all. I'll see what the battery life is but so far, these are great for transforming my Tintin T4s into Bluetooth IEMs.
