One thing all of our phones have in common is that they have replaced the portable media player. These headphones and devices are perfect to pair with your Android and iOS devices and offer functionality previously unknown. If you’re someone who usually switches between a variety of devices with different OS, then these are suited for you.

Quite often you will also find Hi-Fi equipment offering direct connectivity to devices with Android and iOS to simplify the connectivity process.

Wireless Range

You must have most likely noticed that wireless signals do not travel an infinite distance. The farther a wireless signal goes, the weaker it gets. This loss is known as path loss, and it defines the range of connectivity. This range of connectivity is dependent on the wireless protocol in use like Bluetooth. Three classes offer standard ranges of connectivity with Class 1 devices transmitting at 100 mW with a range of 100 meters or 328 feet. Most Bluetooth headsets and headphones are Class 2 devices that transmit at 2.5 mW with a range of 10 meters or 33 feet. Lastly, Class 3 devices transmit at 1 mW with a range of fewer than 10 meters.

KZ AZ09 Pro comes equipped with a highly sensitive microphone so you can enjoy communication with super crisp audio quality. You also get to experience CVC call noise reduction technology - that can effectively offset the call echo and ambient noise while retaining the natural and clear original sound of the call, thus achieving HD calling. You also can enjoy high-definition transmission with aptX decoding, which presents an immersive soundstage and vivid details.



The KZ AZ09 Pro comes embedded with an innovative function that allows you to use your left and right adapters independently with the TWS+ Dual transmission Technology. This technology enables you to connect your left and right ear hook independently. Compared with the transmission technology of the main and auxiliary earphones, the dual transmission delay is lower and response is faster. You also get to experience Adaptive decoding technology with ultra-low delay optimisation. With this technology, the audio and picture synchronisation when playing games is completely synced.



The KZ AZ09 Pro features standard 2-Pin connectors to connect to a variety of in-ears. Compatible with a range of in-ears that have 0.75/0.78mm 2-Pin connectors. The embedded independent power amplifier chip easily matches with multi-unit balanced armature and hybrid technology in-ears. You can transform your wired in-ears easily with the KZ AZ09 Pro and enjoy a convenient wireless experience and HD sound. Any device can be connected as long as it has Bluetooth function.



The KZ AZ09 Pro has been designed ergonomically to offer comfort while wearing them. The ear hooks are made of liquid silicone with a comfortable feel and sufficient elasticity and toughness. Memory shaping can better fit the auricle, making it more comfortable and firm to wear. The AZ09 Pro also offers a battery life of up to 8 hours on the adapters and the charging case provides an additional 6 charges, tootling to 48hrs of battery life. This is truly amazing as you can enjoy music without worrying about battery drains.



The KZ AZ09 offers convenient one-click controls for playing/pausing music, changing the tracks, activating voice control, answering and disconnecting calls. This is done through the one-click button on the AZ09 Pro. Along with one-click controls, you also can determine battery levels through the embedded light indicator. The indicator lights up red when the battery is low and turns green when they are fully charged.

Disappointment at a premium.

It has been around 15 days since I got these delivered and I am already facing issues, I was very sceptical at first since reviews for AZ09 non-pro were really bad, it had disconnection issues and whole lots of problems. After that AZ09 Pro launched and it was very hard to find reviews for it, do you believe that no one really bought these?

So coming to my review, the unit has started malfunctioning in the first 15 days and the return window is closed.
The problem: As soon as I turn on the Bluetooth of my phone or laptop the AZ09 pro instantly connects even if the lid of the case is closed and music starts playing while the lid is on, I have to manually turn off the Bluetooth or pause the music. While I am listening to music and putting them in the case, music doesn't stop either it continues playing 🤣🤣🤣 f*l . Also sometimes it stutters and skips.....great!!! that's what I wanted.

The ticket support system doesn't have KZ in the list so I can't submit a support ticket, the return button is removed from the orders page so now I can't do that either.

The warranty page for KZ on the headphone zone website says this: "Once your claim request is approved, a unique WCID (Warranty Case Id) number will be issued to your case. Once it's approved, the faulty unit has to be couriered to us by the customer."
Just great, after sending the unit to them at my expense, they might send me a working one if they have one in stock.😥☠️

I am using these with KZ ZSN Pro X, was planning to upgrade to KZ CRN or something else but I think there is no need for that. I don't think these TWS will be alive for that long.
BTW It has a Type-C port for charging, the case is a chonker like double the size of a normal TWS, you can't have anything else in your pocket after putting these in.
The connection is fast and seamless, and the sound quality is quite good (my phone supports aptX, your mileage may vary.) The Battery is okay, and the audio quality during calls is okay, but you have speak louder than normal so the person on another side can hear you properly. I was not able to connect 2 devices at the same time, it worked for some people idk.

I hope the headphone zone team resolves this issue somehow or I just wasted 3.5k for nothing.

KZ AZ09 Pro

Disclaimer: Long ramble.
I see that KZ products are not marketed well. So you either stumble upon these amazing products or some stoked friend recommends them. I gambled first on a pair of KZ ZS 10 pro and was immediately blown away by what it has to offer. And gradually I realised it is somewhat for the bass heads(but with no compromise on the other frequency range). I gifted it to my wife who was super happy with them as she loves it's thump. I shifted to KZ ZSX. And I am hooked. I was looking for a true wireless earplug in the market, for taking calls on the move in this pandemic time. And stumbled on KZ AZ09(not KZ AZ09 Pro). Again another KZ. I gambled again. The experience was mixed. I was extremely happy with the audio quality of music or movies. But it had two major significant issues. One, it is uncomfortable where it wraps around your ears, especially, during long duration usage. And second it's mic was of very poor quality. The person on the other end of the call could hardly hear me. The second point failed the most primary requirement(calls). And the third reason, not very frequent though is connection loss for fraction of a second when you are on a bike. Specially while taking turns or turning your head left or right. So long story short I was disappointed partially. For calls, I went back to using the cable that came along with the IEM. And then I stumbled upon these, the subject of the review :). Fortunately enough these didn't exist when I ordered the KZ AZ09. Otherwise I would have hit myself on the face for insufficient research. So I gamble on the KZ AZ09 Pro. This was a super risk because as it was new there weren't many reviews on the net. People spoke about the enhanced comfort but nobody compared the mic with the predecessor. Still I put my buck in it. Thanks to HeadphoneZone, I got it at half the price compared to Amazon. Because Amazon ran out of domestic stock and was importing it to India at more that double the price. And on top of all this I got some amazing playlists card that was HedphoneZone exclusive :). So coming to the main points after the long rant. These bluetooth upgrade cable are the best out there in the market unanimously. 
1. They are modular ie. pair them with any IEM that favors your tuning preference.
2. They are super comfortable
3. They are very secure. Will never fall even if, you are an acrobat.
4. They are to some extent discrete too, specially if you have long hair that covers your hair :). 
5. The mic is better that the apple wireless airpods and equally good as the current version.

1. No volume control. Which is not an issue with me. But I am sure some of you out there will miss that. I however use Siri for volume control, if my phone is buried in my jacket pocket.

We are delighted to know that you are happy with your purchase. We appreciate you taking your time out and writing an elaborative review about the product., shahnawaz ahmed! This will definitely help others to take an informed and wise decision, Cheers!

Not a good product. Stopped working just within 1 month


I purchased this TWS in the month of Feb 2022 and within 1 month unit started giving trouble.

1. Mic was not working (this was with mic model) from beginning
2. After 3 weeks, only right ear piece was getting connected and left ear piece continuously blinks blue light without connecting
3. I can connect either one ear piece at a time not both

I had put trust in Headphone zone and bought this product and really not happy with this.

We are extremely sorry for the disappointing experience you had to go through with us, Keshav. Our team is in touch with you and will surely help you out in resolving the issue.
