Twistura Beta Quick Review: The Power of Glass Diaphragms
Numerous budget-friendly Chi-Fi brands are pouring out, though this brand, Twistura, stood out for me in particular, prompting me to decide to cover it as a review. Making a new entrant to the scene, Twistura followed up their initial D-Major and D-Minor releases with their latest budget flagship, the Beta. In this review, we will go into an extensive sound impression of Beta and compare it with other budget Chi-Fi IEMs.
Packaging / Accessories / Cable
The Beta comes with a generous amount of accessories. Other than the earphones, Beta comes with a 4-braid OFC cable, 3.5mm/4.4mm modular plugs, 9 pairs of eartips with different sizes/shapes, 3 pairs of nozzles, and a purple leather carrying case. The carrying case is made of smooth materials on the inside for protection. The stock cable has a modular plug that conveniently allows changing between 3.5mm and 4.4mm connections. The cable is slightly thicker than average stock cables, yet it’s very easy and comfortable to handle thanks to the soft and light wires.
Earpieces Design (Techs / Drivers / Features)
The Earpieces are made of CNC-machined aluminum alloy with a grey, matte finish. The earpieces are smooth to the touch, and they sit comfortably in the ears. The air vent also relieves the air pressure. Under the hood, Beta employs a single 11mm Dual-Magnetic / Dual-Cavity Dynamic Driver. The notable features of Beta are not only its uncommon 11mm driver diameter, but also the usage of the world’s first “Planar Glass” Diaphragm.
The Planar Glass composite 1DD offers superior rigidity and distortion compared to DLC (Diamond-like Carbon) drivers. The Dual-Magnetic design also serves to strengthen magnetic force and control, leading to better sonic efficiency and accuracy. Having the design to have a Dual-Cavity design allows refined airflow and deeper bass reproduction.
Lastly, the interchangeable nozzles allow you to tune the sound to your taste. Having the Silver set as the Default or Reference, Gold offering a more vocal-centric sound, and the Black offering a sound more emphasized for treble/instrumental.
Sound Impressions: Bass
The low end of the Twistura Beta is defined by its punchy and energetic character, offering a sub-bass extension that provides a satisfying rumble without becoming overwhelming. It focuses on a quick, clean transient response that keeps the rhythm feeling tight and well-defined. While it doesn’t possess the massive, lingering decay of a pure “basshead” IEM, it offers enough texture and impact to make percussion feel visceral and engaging.
Sound Impressions: Mids
The midrange is rendered with a clean and slightly forward presence that gives vocals a clear sense of transparency and air. Instruments like acoustic guitars and pianos carry a natural timbre, avoiding the thinness that sometimes affects budget hybrid designs. There is a noticeable clarity in the upper-midrange that brings out the nuances in female vocals, ensuring they remain the centerpiece of the performance without introducing unwanted sibilance or harshness.
Sound Impressions: Highs
Leveraging its planar component, the treble on the Beta is crisp, airy, and remarkably well-extended for its price bracket. It provides a fine sense of micro-detail and shimmer that adds an open, spacious feeling to the overall soundstage. The high frequencies are tuned to be resolving yet smooth enough for long listening sessions, successfully capturing the sparkle of cymbals and string overtones with a sense of precision and speed.
Compared to Kotori Audio Vampire (Review link)
When compared to the Kotori Audio Vampire, the Beta offers a much more technical and “modern” hi-fi presentation. The Vampire is known for its unique, warm, and analog-like soul that draws a surprisingly thick and organic sound from its single BA driver. While the Vampire excels in creating a lush, intimate vocal experience with a “vintage” charm, the Beta provides better extension at both ends of the frequency spectrum and a more transparent, airy atmosphere that favors resolution over pure tonal warmth.
Compared to Oriveti OD200 (Review link)
The Oriveti OD200 provides a larger, more expansive soundstage thanks to its patented airflow distribution system, giving the music a grander sense of scale. In contrast, the Twistura Beta offers a more intimate and focused imaging capability, with its planar driver delivering a sharper sense of edge definition in the treble. While the OD200 has a more “breathable” and relaxed character, the Beta feels more energetic and immediate, especially in the way it handles fast-paced transients in the upper frequencies.
Compared to BQEYZ Wind (Review link)
The BQEYZ Wind utilizes a bone conduction driver to provide a unique vibrational texture to the lows and mids that the Beta’s traditional air-conduction setup cannot replicate. The Wind feels more atmospheric and physically “fun” in its delivery, whereas the Beta aims for a more balanced and traditional reference-style clarity. While the Wind offers a more holographic and three-dimensional stage, the Beta counters with a cleaner upper-midrange transition and a more precise, planar-driven treble response that feels more detailed in a traditional sense.
Final Thoughts: Very budget-friendly yet HQ sound!
The Twistura Beta stands out as an exceptionally well-rounded budget IEM that offers a level of build quality and functional modularity usually reserved for much higher price tiers. Its hybrid “Planar Glass” configuration delivers a sound that is both technically impressive and musically engaging, successfully balancing energy with refinement. For the audiophile seeking a versatile, high-resolution entry point that doesn’t compromise on accessories or aesthetics, the Beta is a very compelling, highly recommended choice.
