CCAKZ Castor Pro Tunable in Ear Monitor, HiFi Improved Bass in Ear Headphone, Dual-Dynamic Driver Gaming Earbuds, IEM Earphones with 2PIN-C Detachable Cable

Pretty much no bad things to say about these IEMs. I did tons of research and spent so much time looking at different options around this price point because I wanted affordable and extra bass. These absolutely have it. When plugged into my really high end pre out these sound so much better than any headphones in general that i’ve heard. Although, plugging them into my low end school chromebook, there’s a massive sound quality difference which is to be expected. If you can properly power these, they sound so incredibly good. You could consider me a bass head so I was particularly looking for above average bass performance and these do no less. All without drowning any other frequencies out. Every single sound stage is there and clear. They also fit incredibly well and I have no issues with them feeling like they would fall out. If you’re trying to decide between all the countless options, want good bass, tuneablity, and fit, just buy these. The low bass is even there somehow with dual 10mm DD’s which blows my mind. There’s not a single part of the sound spectrum that’s drowned out or dropped off. They sound so good. Sadly even way better than my airpods pro 2nd generations.

These are a no brainer. The sound amazing for its price and above. Now if you're a vocals focused music lovers these are going to be to colored for you in the lower mids. But for Metal, Rock, Electronic and all their subgenres these are a steal. Most audiophiles spend too much time listening to "Audiophile" tracks and buy equipment to listen to those tracks on. Most people want to enjoy the music not every little detail but still want to ENJOY theusoc with good quality sound with depth, Bass extension, punch, rumble, as big a soundstage as an IEM can provide which is none, have high speration so you can feel where all the instruments are and here their individual intricacies. These do that with sparkle with two peaks that if you use EQ can be midigated quickly. These are a no brainer every day carry IEM.

Decent for the price. Annoying that they don't include a cable cinch. If they included a cable cinch (to tighten the cable behind your head) they probably wouldn't fall out as easily. Four stars because I'm judging the audio quality of these compared to their price. If you don't factor in the low price I would give them a two star rating.

Very low sound quality. Dollar store quality.

So it takes a couple of hours to break the Castor Pro’s in. Once they are broke in you will be blown away by how great these sound. Now you’re not going to get great sound from the included cable. You will need to upgrade the cable and run these through a DAC. If you would like to just cut the cable and go wireless, I would recommend the CCA BTX Bluetooth ear hooks. The BTX’s sound so much better than any of KZ AZ series of Bluetooth ear hooks. I would recommend using ear tips that are one size bigger as they seal up and improve the overall low end.

For the price and quality how can anyone go wrong!!!With the individual equalizers on each ear bud is perfect to dial in on your sound queues to maximize your gaming and listening experience

The sound on these things are great when it comes to listening to music or watching a movie but for playing games where footstep audio is crucial not so much. I would often times here the footsteps but the direction would be completely wrong. Left sounded like right and vice versa, which had me thinking I had them on incorrectly. Also the mic would echo according to my friends.Came back to say that after messing around with them, it turns out the ears were labeled wrong.

Blew my mind. Its only $25.. what are you waiting for....?My musical taste knows no bounds and am in an edm/bass kick right now and they leave no room for disappointment. It's like hearing music again for the first time... again, what are you waiting for?I am using SOUND beautifier by swiss selection for my eq... beautiful results imo.EDIT: I am now using Wavelet instead of sound beautifier. Galaxy 25 ultra.
