HEAR YOUR MUSIC COME ALIVE WITH THE ALL-NEW ALTIAT CAL.1H OPEN-BACK HEADPHONE
Altiat, pronounced (all-t-a), is a Manufacturing company based in India - Mumbai at a state-of-the-art facility. Altiat is a prime example of the make-in-India program launched in 2014. Altiat is privately owned and is on a quest to become a household brand in India and international markets. The brand-new Cal.1H (pronounced Caliber 1H) from Altiat boasts an infilled PET (Polyethylene Terephthalate) diaphragm and a 50mm electrodynamic driver. First synthesised in the 1940s, PET was invented independently by DuPont (Mylar) and ICI Films (Melinex). Because it is a flexible and workable material, it has omnipotence in audio. Polyethylene Terephthalate is a polyester film made from stretched polyethylene terephthalate (PET). It has high tensile strength, chemical and dimensional stability, transparency, and reflectivity. Taking this into consideration, Altiat used the PET diaphragm, which gives a superior response when an electrical signal passes through it. Altiat has tuned the dynamic driver to match the Harman target curve. Sound-wise, Cal.1H has a very pleasant tuning that will appeal to most audiophiles. The presentation is exceptional and accurate. Instead of going for 'reference', neutral and something perhaps a little "niminy-piminy" in a determination to win the hearts and minds of the discerning audiophile, Altiat has instead opted for full-range and refined performance that will appeal to a broad audience.
FEEL THE MUSIC PULSING THROUGH YOUR VEINS WITH A 50MM DYNAMIC DRIVER
The Altiat Cal.1H features a 50mm electrodynamic driver that delivers pristine audio performance. Technically, Cal.1H displays the excellent attributes that dynamic driver headphones usually have when reproducing low frequencies. The Cal.1H offers outstanding bass extension, which adds depth and rumble to the sub-bass. Altiat Cal.1H has bass quality rather than quantity. The midrange tuning on the Cal.1H is excellent. It’s linear throughout, with clean fundamental tones, and a good presence in the upper midrange. It has fantastic tonality, depth, and layering. Male and female vocals sound precise with body and weight to their presentation. The treble range is for the most part pretty good on the Cal.1H. It’s not warm, but it’s not bright either, and overall it’s set at a level that will be comfortable for most listeners. The Cal.1H does extend nicely into the upper treble with good holographic and airy representation, properly representing all the harmonics and overtones in that region. Cal.1H has one of the more spacious and open-sounding presentations. For soundstage width, it’s roughly on par with most open-back headphones and can convey a better sense of distance and precise instrument separation. Additionally, Cal.1H delivers exceptional layering capabilities, with all instrument and vocal lines distinguished, allowing you to experience pure sonic tranquillity.
EXQUISITELY CRAFTED FROM A UNIBODY ALUMINIUM AND SPRING STEEL
The build of the Cal.1H is primarily unibody Aluminium. The Headband is a mixture of aluminium and spring steel with Delrin buffers which ensure clean action against the surfaces to avoid metal-on-metal fatigue. Almost all parts of the Cal.1H are precision machined on CNC turning and CNC milling machines. The Cal.1H is available in colourways like Gunmetal Grey, Aluminum Silver, Anodized Black, and Solid Ash. You now have options from Altiat to select the perfect colour way that you require. Every colour has received its final coating. Aluminium housings have a gunmetal grey powder coating. Housings made of raw aluminium are abrasively sandblasted for aluminium silver. For solid ash that has been machined from a single piece of Ashwood while keeping the Cal. 1H's 3D contours. A 6.35mm unbalanced termination and stock velour earpads are included with the Altiat Cal.1H.

Comfort and build quality is top notch. 👌🏽
You can play around with the pad filter to change the sound. With the filter on you get a balanced sound and with the filter off it sounds bright.
Also I would suggest pad rolling. I’m using perforated earpads with it. They sound more open with perforated pads.
The price is a bit higher than what it should be. But they can easily compete with headphones in a similar price range.
Note: Sound is subjective. Might not suit you like it did me. Audition it before buying.
Hey there, nothing makes us happier than knowing you loved your purchase, hope you had a comfortable shopping experience and thank you for the great review and ratings!
Design wise the ear pads could’ve been made of better material, but, the comfort is quite decent.
Soundstage is brilliant and the vocals have an almost live-performance-like feel to them. Really good value for money!
We're really happy that you have such great thoughts about the product and thanks for the amazing review!
