RAPTGO x HBB Collaboration IEM 

Raptgo has partnered with one of the legendary audio reviewers in the audiophile world, “Bad Guy, Good Audio Reviews” (also known as Hawaian Bad Boy), to upgrade the previous success-Hook-X in-ear monitor to achieve next-level ultra-performance. To obtain greater analytical power and sound dynamics, the new Hook-X has increased the size of super strong magnet application to optimize magnetic circuit with 7*2 dual array N52 magnetic circuit design. Thinner diaphragm is adopted for better low frequency dives and richer dynamics. Combined with HBB’s years of experience with thousands of HiFi audio products, the new Hook-X certainly will bring a storm to the hybrid driver world

Novel Concept, Precise Execution

The new Hook-X follows its predecessor with a hybrid in-ear monitor design utilizing the planar magnetic driver in combination with a piezoelectric (PZT) driver. These two driver types are among the most sensational driver technologies in the audio industry, and have never been utilized together in an IEM format. We took on this momentous concept, and through careful engineering and testing, have successfully created an IEM that encompasses the powerful characteristics of these drivers fashioned with tonal perfection. Unlike other IEM novelties that simply cram in hyped drivers, we are proud to achieve a product that is tuned to balance and allows the listener to both appreciate the acoustic superiority of these drivers as well as enjoy the music through their harmonious tonality.

Custom Made 14.2mm Planar Magnetic Driver

The planar magnetic driver utilizes a thin ribbon suspended between two powerful magnets through which electrical currents run. The advantage of a planar magnetic driver is the extreme responsiveness compared to dynamic or balanced armature drivers due to its lower mass and strong magnetic field. We manufactured our own large 14.2mm planar driver, which is driven by powerful N52 magnets. The precision of this driver allows incredibly punchy and impactful sub-bass response, as the ribbon is more responsive to transient signals. Furthermore, the full frequency range is effectively extended from 20Hz to 40kHz to produce an upper treble response previously unobtainable in an IEM. Internal housing structure design and acoustic damping system were carefully brought about to achieve a balanced target tuning, a rarity among IEMs that utilize the planar magnetic driver.

12 Layer Double-Sided PZT Driver & Upgraded Thick Double-sided Conductive Silver

The piezoelectric driver achieves enhanced treble response through vibration of piezo elements within the housing. In cooperation with an external team with military engineering backgrounds, we have designed a double-sided layering system consisting of 12 ceramic piezo elements that has been fine-tuned after more than 100 acoustic shock simulation experiments. Each of our PZT drivers undergoes 52 complicated processes during production, and is hand tested and paired. In addition to the planar magnetic driver’s extended treble response, our PZT driver adds an extra dimension of sonic resolution and air that is incomparable with typical balanced armature or even electrostatic drivers.

Improved Open-Back Cavity & PZT Acoustic Shock Drive Bracket Structure

For both tuning and acoustic properties, the new Hook-X adopts an open-back design. This allows the maximum amount of airflow to highlight the planar magnetic driver’s characteristics. Additionally, this opportunity opens up the soundstage compared to typical IEMs, mimicking the openness and realistic playback of open-back planar headphones. Finally, the open-back design prevents the buildup of pressure within the ear to reduce hearing fatigue. Moreover, the newly designed PZT acoustic shock drive bracket structure greatly avoid transmission loss and vibration to present a better sound performance. The housing of the Hook-X was software designed after a large number of simulation experiments to match the typical ear angle and wearing experience. Each unit is crafted from a high-precision 5-axis CNC to ensure uniformity of the acoustic chambers. From the housing design to the driver assembly, each aspect of the Hook-X is a demonstration of workmanship, engineering prowess, and acoustic tastefulness..

Optimized Interchangeable Connector Cable

The new Hook-X comes with a optimized modular connector cable terminated to 0.78mm 2-pin jacks. This means that you can simply swap out the connector between the 4.4mm and 2.5mm balanced and 3.5mm unbalanced jacks to use with any of your devices. This incredible design limits the need for bulky adaptors. The cable itself is made using OCC silver-plated coaxial shielded wires that enhance the transparency of the hybrid drivers.

Based on 4 reviews

So I have had this for roughly two months now, and can honestly say I am past the honeymoon period and my verdict has landed: These are spectacular.

SOUND: After being somewhat disappointed by the Blessing 2: Dusk, I set out to find a replacement with a tuning more to my liking. Traditionally I listen to a wide variety of genres, but generally I am a fan of rhythm based music, so the midbass tuck from the Dusk was a bit too analytical for my taste. These however are much more engaging and fun. Thanks to the planars, the bass is super fast, so even if there are a lot of things going on in the song, you can still hear all the details! This is my first dive into planar IEMs, but I do believe these hit the sweet spot of being able to appeal to a wide variety of people. The bass is never overbearing. Very fun listen!

GAMING: I also use these for gaming, and as Fresh Reviews (on YouTube) has stated, these are amazing for it! I gravitate towards these more often than my more expensive Moondrop Variations, both because the soundstage seems wider, so you get more immersed into the game, as well as being able to pick up more details compared with the Variations.They are also miles ahead in terms of comfort! Much less intrusive fit, both on the nozzle and shell. I can have these in my ears for hours without feeling much strain.

CABLE: I feel it needs to be emphasized how lovely the cable is! This is my first time using a cloth cable, so that may partly why it feels so different to me. However, it can't be understated, the cable is SOFT and it has perhaps the least amount of microphonics out of any cable I have tried. This is honestly my favorite cable, even up against more expensive ones I own. I ended up trying to find where these were sourced, and the cable alone costs about 50 dollars, without the multiple determinations which this one comes with. Very good value.

CASE: The case is simple and perfectly compact. I use this case as my daily case for whenever I am out of the house.

All-in-all, I can't recommend these enough! In the grand scheme of "which planar IEM to get" I can't say whether the Tangzu Zetian Wu, Letshuoer S12, HBB Heyday or 7Hz Timeless are better offers, but these were very much worth the price, and I would buy them again!

Solid set that is fun for hours. Comfortable fit and is excellent for music or gaming.

Nice upgrade

The new Hook X HBB is wonderfully tuned and balanced. Very musical and sonically satisfying. Good job everyone.

Very detailed and engaging with excellent price

Compared with the original Hook-x (i own both) the upper bass boost probably generated through the bone conductor is much recessed in the HBB tuning. I love the HBB tuning in the higher regions. Cymbals sounds crisp like in a live session. This is my first IEM with such a good representation. As the original version this IEM is engaging and fun to listen. I think the price is very competitive and can compete without problems with my high priced IEMS such as Sennheiser IE600 or Campfire Solaris. The IE600 has a similar tuning to the HBB Hook X.
The HBB Hook X cable is the same cable as the original Hook X cable but in blue.
The cable looks good and represents a good value with the universal connectors but delivers a granular representation in the highs. I am using a DUNU silver plated cable instead with much better acoustic results.
Thanks to Linsoul for the excellent and always reliable delivery service to Switzerland.
