KZ x HBB PR2

Really Good

These are my first planar IEMs and so far I feel quite happy with their performance. I'm giving 4 stars because the cable is not the best one and the built material, considering the price, could be better. However, I understand to have such price point with the technology involved you need to compromise something.

Treblehead's IEMs

These have very good resolution, the bass is tight and controlled and the midrange is clear. However, there is too much upper treble. I changed to narrow bore tips and listen to them with the balanced cable. These are so low sensitive that they require a separate headphone amplifier. The construction and the cable of these is okay. The foam tips fits well and these don't drop of your ears. I think that these are good value for the price if you can tame the upper treble.

High end sound, budget price

Pros - very transparent sound - exciting yet non fatiguing treble - included ear tips actually not bad - a detail beast on balanced output - crazy value for money - handsome design Cons - needs good amplification to truly shine - included 3.5mm cable is usable but very basic The PR2's are my daily drivers. I use them on my Fiio M11 Plus ESS, connected to the balanced out. The resulting sound is the best I've ever heard out of a set of IEMs. They surpass my Letshuoer S12's, which cost more. The PR2's even rival my Thieaudio Clairvoyance set, which cost way, way more. The Clairvoyance still have a unique sound, so I'm not quite willing to give them up yet. But I haven't used anything for serious music listening except the PR2's since acquiring them. They are that good. While the PR2's sound just fine on single-ended output, they are even finer when heard balanced. It means having to upgrade the cable, but the PR2's deserve it. In my experience, the ear tips that come with IEMs are often a mismatch with the product. But to my ears, the ones included with the PR2's actually don't get in the way of the sound, which is progress. That said, I still experimented with different ear tips. I settled on memory foam tips from a different set of IEMs (from Tin Hi Fi) that really brought the best out of the PR2's. The PR2's are an insane value for money. They deliver good sound right out of the box, and compete with much more expensive headphones. As long as the audio source has the juice to drive them, the PR2's will not disappoint.
