If you don't give it power, its very sizzling and hard to listen to. Once you do, most of the sizzles are gone, mids are full and sub bass is clean tight and satisfying. In stock tuning, this thing has deep clean sub bass that's missing on other planars like leshueor S12 or timeless. Those just have boomy annoying mid bass.The midranges are good and very detail, every bit as clean and resolving as more expensive planars. It's also very open and spacious on par with my $1000 akgn5005 amd hifiman Ananda.It sounds less planar sounding than other planars. Give it some EQ to tone down the treble and there's nothing that can touch this for the money.

I spent my time with headphones and have recently gotten into more IEMs. It's truly amazing how wonderful these sound at this price. I first listened to them with an iphone, then old android phone and they were so quiet. Stepped up to my portable dac, and still required being turned up to about 75%.Then I finally plugged them into my desktop amp with a balanced cable, they came to life. The speed at the transitions between notes is amazing. I was picking up the little nuances in songs, that I hadn't noticed. Notes didn't hang around anymore, they were just gone when they were supposed to be.They're large and comfortable to an extent, but it depends on ear size. I switched the tips to my new favorite W1s.They're not the best thing since sliced bread, but it depends on what is missing in your collection. I have some that I listen to when I want to have fun. These make me want to relax and listen to songs that I thought I already knew.

As long as accepting this does not give strong bass but rather has higher gain on high frequency, it gives good sound for its price. However for been frequently slept on over after a year one of the two pin connectors finally shattered.

These KZxHBB PR2s are amazing for their $50 asking price. The planar driver can make sounds you've never heard before in an IEM and are extremely dynamic and fast. It's truly amazing what you can get for <$100 these days in IEMs. There's basically no reason to spend big money on the old school brands (ie: Shure/Etymotics/Ultimate Ears). The biggest con is that you really need a headphone amp to make these buds shine. They have very low, 94dB, sensitivity. So if you just plug them into a USB dongle or straight into a phone or portable audio player you're not going to get much volume out of them. With a decent USB DAC dongle, I had to turn the volume up to 90% to get usable volume. Using my DAC/amp setup, I still need to turn it up to 60-70% whereas most others headphones are down at 40%. If you have the power to drive these properly, they really do shine. If you don't, just skip them as they will be dissappointing.

these sound kinda meh with the supplied cable. like others suggested I swapped out the cable for a better balanced version, new foam tips and wow! these really wake up with a bit more power. I split my time between these and my DT990 250ohm cans because they sound so awesome...a no brainer for the price.
