This is TANGZU’s first initial foray on the headphone market as they are known mostly for their IEM products and now I will introduce to you their first mode, the TANGZU OX DEMON KING. This headphone has an open-back design and it sports a large 85mm planar magnetic driver on each side of the stereo channel that were installed in a solid aluminium alloy earcup structure with a leather earpad cushions, and also features a detachable just like most of the midrange cans in the market. Will this headphone be able to penetrate the crowded headphone market and will have a fighting chance to deal with more firmly established Hi-Fi headphone brands in that market segment?
PROS:
● Pretty robust and well-constructed frame
● The overall design has an excellent structural integrity with exquisite metal craftsmanship.
● Solid yet flexible headband with a firm swivel mechanism for rotating earcups.
● Detachable cable.
● Its earpad cushions are quite soft and supple for comfortable wear and lessens pressure clamping for long listening sessions.
● Its large planar magnetic drivers deliver an exceptional detailed resolution, snappy transient response and low distortion rating.
● Musical, engaging and exciting yet balanced sound profile
● Fast, punchy, rumbly yet clean bass response.
● For a planar magnetic headphone, it has a deep, rich and fullness on the note weight for bass-clef instruments and low octave male vocals.
● The midrange has a balanced tone with ample warmth and energy for a lively and engaging sound from vocals and instruments.
● Excellent for enjoying the quality timbre from all vocal types
● Crisp, sustaining and airy sound from some instruments like strings and woodwinds.
● Brassy, full and metallic sound from brasses, and then, a hard, resonant and sharp sound from percussive instruments.
● Bright, shimmering and airy treble response.
● Excellent technical performance from the spacious soundstage up to its crystalline and detailed resolution capabilities.
CONS:
● Since this is a planar magnetic driver, therefore it is quite power hungry that you need a more powerful source to drive this headphone at optimal level of performance.
● Well, open-back design, therefore it has a poor noise isolation as it leaks sound
● Limited swivel rotation.
● It doesn't have any storage case nor carrying pouch for this headphone.
● This one is somewhat a bit too coloured for ardent neutral heads looking for flatter, more balanced with minimal to none colouration of its overall sound profile aiming for accuracy for more faithful sound reproduction without any unnecessary overemphasise boosting on some parts of frequency response.
● A bit energetic tuning that might sound a bit piercing, edgy and tinny in which might exceed the listening threshold of the treble-sensitive folk.

Ordered for the looks. Kept for the sound quality. Well done!
Great Delivery Time for the holidays!
Buildquality looks very fine! Soundquality is gorgeous.
I ordered (from South Africa) and received my delivery in 5 days🙆🏾♂️ I was surprised at how fast I got it.
The sound quality is amazing. I use it for music, gaming and most recently for DJ’ing. I definitely am a fan for life and will be buying more products in the future. My ears are small so I was very worried about the fit but they fit perfectly with the right tip size.
Keep up the good work.
