7Hz

So straight out of the box. Seated in my ear perfectly gel cushions were soft no scratching in the ear. There are smaller than my other one which make them alot more comfortable. Sound quality is absolutely amazing alot more depth and I use them for gaming placing sounds was a breeze. The fact that I found a company that supplies them here even better the one place I bought from was very expensive with the import fees thank you unbound audio 20/10 definitely be back for more

I purchased the microphone transmitter to allow me to use my favourite corded mic. I wasn't expecting too much. However, I was surprised at the clarity, of the distsnce it transmitted. Used it for about 3 hours during an awrd ceremony at a distance of approximately 25 metres and it performed magnificently,

Used this transmitter with one of my favourite mics which is the reason for wanting it. It worked 100%, after a straight three hours the battery had hardly gone down. Distance was approximately 25 metres and it was clear with absolutely no interference. Now I am confident enough to use it regularly. I will also test it in ‘line’ mode sending signal from one mixer to another approximately 30 metres away and see how it performs.

I love them

Best service and product

I was advised by a pro drummer to use this exact product. I can't believe the difference. Crazy what a difference a good product makes. Get an extension cable if you do not have your audio input on your belt.

These are noooooooiiiiiiiiiiiiiice

I got these today, and after testing them I have to say they are the best sounding things I ever placed in my ear.🤣 I can hear sounds I never heard before when listening to music. I highly recommend these

I was thrilled that my order arrived the very next day! The quality of these earphones is fantastic—I'm a video editor, and they revealed sounds in my previous voiceover clips that I had never noticed before, prompting me to re-edit them. Thanks to these earphones, my work is now even better. They're also incredibly comfortable to wear. I highly recommend them!

I love the sound quality, it really does what its supposed to and more. As a vocalist, I do not have to strain my voice, I can project just the right way and still preserve my voice as I usually sing for long periods of time.

I bought the CCA 12s from Audio Unbound at a phenomenal price. can not take these earphones out of my ears. The quality is simply outrageous and the depth of sound is unparalleled. I can not recommend these guys enough... I will definitely be using them for all my professional needs going forward!

This is the best wireless system for guitars and in-ear wireless systems

So far I've used this for two band practices , no drop outs , sounds better than some of my cables. Latency <5ms so not detectable for a guitar or bass, if you want to use on electronic drums it also works flawlessly. I also use it on a distortion pedal.

What an awesome surprice regarding the quility of the sound.

Simply put: I was looking to upgrade my current IEMs for something that has better and deeper bass response; going from 20Hz - 20K Hz to 10Hz - 20K Hz. These do not disappoint. Watching a movie or playing a video game is so much more impactful. It feels more like air pressure, than bass "sound".

I can fully endorse this product.
