In terms of design, the housing features an in-ear monitor structure, and the back panel isconstructed from blue stabilized wood. Theprimary black color scheme, accented withroyal blue and gold accents, creates a subtleyet luxurious aesthetic.To easily distinguishbetween the left and right earbuds, the bluering pin represents the left earbud, and the redring pin represents the right earbud.
The standard 0.78-pin connector is used

Unit Content
The XSPl utilizes a custom 15mm DLCcoated large-magnet dynamic driverdesigned to deliver exceptional soundquality. Furthermore, it features a uniquesound-guiding rear chamber structure,comprised of a buffering sub-chamberand a series ofinterconnected flute tubesThis design not only optimizes the soundpropagation path but also enhances thedetail and depth of the sound.

Sound Style
Compared to the QJ21 and ANSATA PRO, the XsP1boasts a more vibrant sound, with a fuller, richermidrange and superior high-frequency extension.Its sound quality surpasses the ANSATA PRO, andits listening experience is superior to the QJ21.The XSP1's sound color imbues vocals withgreater vitality, better expressingemotionalfluctuations and providing fuller vocal power. interms of vocal performance, male vocals arecomparable to the QJ21, while female vocals arebrighter, more detailed, and more transparent.Furthermore,the XSPl boasts greater verticaldepth of soundstage. lts sound texture is soft, yetit packs a punch at crucial moments.

Tuning Structure

A resin-printed secondary chamber, asound-guiding rear chamberstructure,includes a bufferingsecondary chamber and a set ofinterconnected flute tubes. Thiscreates a more naturalsoundstage,eliminates falselow frequencies, and extendsthe headphone's frequencyresponse.

calbe Materials
Using a combination of pure silver andcopper wire for the hand-built circuitsignificantly improves sound quality. Puresilver wire plays a crucial role in headphones,providing extremely high-frequency outputand enabling sound to travel faster. Thismeans you can hear high-pitched details.such as the high notes ofinstruments or thehigh notes of vocals, more clearly whenwearing these headphones.Copper, on the other hand, is highlybeneficial for mid- and low-frequencyperformance.lt enhances the richness andwarmth of vocals. Using copper as the wirematerial allows you to better perceive thevocals in your music, ensuring that theresonant tones of a singer and instrumentsare conveyed more realistically.

During our field testing, we first examined the low-frequencyperformance of flat-head headphones. Due to their non-sealeddesign,flat-head headphones may have certain limitations inlow-frequency performance. However, by using a 7l1 artificialear for field testing, we were able to more accurately assesstheir low-frequency performance.In addition to low-frequency performance, we also tested otherfrequency bands. By comparing the sound quality acrossdifferent frequency bands, we gained a more comprehensive understanding of the overall sound quality characteristics of flat-head headphones.We also considered the impact of differentmusic genres and sound sources on sound quality to ensure theaccuracy and reliability of the test results, The test results are asfollows:
