KZ x HBB PR2 - The Planar Revolution Continues

KZ has recently introduced their latest in-ear monitor featuring planar drivers, the PR2. This model boasts an impressive 13.2mm planar driver configuration. As the successor to the PR1, which unfortunately I didn't get a chance to try, I am grateful that KZ has provided me with the opportunity to experience the PR2.

PACKAGING:

While the inclusion of barebone accessories doesn't bother me in KZ's budget segment, I feel that for models like the PR2, it would have been a notable improvement to have a case and a better cable included. It's not surprising to see that the inclusion of accessories remains the same, regardless of whether it's a budget KZ IEM or a "flagship" model. However, I acknowledge that this is solely my personal opinion, and I hope that KZ considers such feedback moving forward.

BUILD QUALITY

I must praise KZ for their continuous commitment to improving the build quality of their in-ear monitors. The planar driver in the PR2 is housed in sturdy resin shells, reinforced with a metal faceplate. I personally would prefer if KZ started utilizing recessed 2-pins instead of the QDC type pins, particularly for their higher-priced models. Nevertheless, the overall build quality of the PR2 remains commendable.

SOUND

The PR2, despite having planar drivers is not cursed/blessed with the so called "planar sheen". The PR2 showcases KZ's signature warm V-shaped sound signature, which has been a defining characteristic of their brand since its inception. Over time, they have continuously refined and improved upon this sound signature, making it even more enjoyable.

BASS

The bass response of the PR2 offers a moderately thick presentation, although it may not have the same level of impact as some of KZ's previous models like the ZAS. This distinction can be attributed to the PR2's use of a planar driver instead of a dynamic driver, which leads to a bass that is less dense and impactful compared to a dual-driver setup. The focus of the bass is primarily on the sub-bass frequencies, while the midbass has a lesser impact and thump in the lower frequency range. However, despite this difference, the PR2 still performs admirably in the lower region and can satisfy the preferences of some bass heads.

MIDS

The midrange presentation of the PR2 strikes a subtle balance between clarity and engagement, with a slight recessed quality. While the vocals may not possess the same level of euphonic richness and thickness typically found in warmer planar sets, they still deliver decent and clean vocals. Instruments, although not prominently pronounced, maintain clarity and exhibit good separation within the mix. Overall, the midrange of the PR2 delivers a smooth and acceptable musical performance, providing an enjoyable listening experience.

TREBLE

One notable surprise with the PR2 is its departure from the typical treble performance found in other KZ in-ear monitors. In the past, certain models from KZ were often criticized for having harsh and shrill treble. However, this issue is not present in the PR2. The treble is not excessively airy, but it still provides a commendable level of clarity expected from a planar IEM. While the PR2 offers a subtle touch of sparkle to certain tracks, it doesn't deliver an exceptionally vibrant brilliance. Nonetheless, the treble is commendable for its absence of harshness, shoutiness, and sibilance, which is definitely a positive aspect of its performance.

TECHNICALITIES

While the soundstage of the PR2 is not particularly expansive, it offers a decent sense of space considering its price range. The soundstage doesn't sound lacking or compressed, allowing the music to breathe and avoid feeling congested. In terms of imaging, the PR2 performs admirably, providing a clear sense of placement for instruments and vocals as they progress across the left and right channels. The separation between individual elements within the music is also commendable, even in busier tracks where multiple instruments and layers are present. Furthermore, the PR2 exhibits the ability to capture fairly subtle micro details, adding an additional layer of depth and nuance to my listening experience. The PR2 might demand more power to unleash its full potential. Then again, this is a $40 planar in-ear monitor but it fares decently on its own. 

COMPARISON

I don't have anything to compare against the KZ PR2 within its price range because I haven't been exposed that much to its potential competitor the Celest Gumiho which also houses a square-planar driver. I also can't compare it to its older brother the PR1 since I haven't tried it at all. However, I can try to compare it with much expensive planar sets I tried. It's important to note that these comparisons highlight the distinct strengths of each IEM, rather than determining which one is superior overall.

1. MUSE HiFi Power - Ahh yes, I forgot I reviewed the HiFi Power before but if you want to experience the worst "planar sheen" in a planar driver IEM. You might want to torture your ears with the MUSE Hifi Power. Too harsh? It's mutual then. Joke, while the MUSE Hifi Power is decent in term of details and some technicalities, I find the MUSE Hifi Power to be very aggressive and spicy in the treble region.  It also has the tendency to be sibilant and shouty in which the PR2 is absent with those nuances. Besides, the MUSE Hifi Power is too bulky, top it off with the uncomfortable sound. 

2. TANGZU Zetian Wu - When comparing the PR2 and the Zetian Wu, both IEMs exhibit a departure from the typical "planar sheen." However, the Zetian Wu leans towards a more euphonic sound signature, offering a weightier lower region compared to the PR2. On the other hand, the PR2 excels in terms of soundstage, providing a wider and more spacious presentation compared to the Zetian Wu. While the Zetian Wu boasts a thicker and more lush tonality, the PR2 delivers a more open and detailed sound reproduction. 

3. LETSHUOER S12 - Similarly, I can provide a comparison between the Zetian Wu, PR2, and the S12. The S12 stands out for its superior warmth and lushness, surpassing both the Zetian Wu and the PR2 in this regard. On the other hand, the PR2 offers more aggressive treble and decent imaging capabilities. However, when it comes to the engaging quality of the lower registers, the S12 outshines both the Zetian Wu and the PR2. It delivers a captivating and immersive experience in the lower frequencies. Additionally, the PR2 reveals more sparkle in the treble region, adding a sense of clarity and detail compared to the S12.

Pros:

• Improved sound from KZ
• Mild V-shaped signature
• Clean, decent mids
• Forgivable and inoffensive treble
• Decent technicalities for the price
• Cheapest planar driver so far
• Robust build

Cons:

• The bass doesn't have that much dynamics
• The QDC connection will always be a con for me
• Barebone packaging for a "premium" offering from KZ
• Not the most technical planars around
• As planars should, it requires more driving power to unleash its potential

In conclusion, the PR2 truly shines as one of the top budget planar IEMs, making it an excellent choice for those with budget constraints. It represents KZ's latest and improved offering, presenting a fresh take on their well-known dynamic-driver V-shaped sound signature. With the PR2, you not only get the familiar KZ quality but also a more refined and matured package that showcases the brand's continuous growth and development.
