Design and Build Quality

The 7th Acoustics Supernova allows for customizing your own IEM design, including faceplate and shell. The review sample received features a red faceplate and black shell. The outer resin material exudes a premium look and feels solid in hand. The brand's logo is elegantly silvered on the faceplate, along with the Supernova emblem on the opposite side. The IEM cable is robustly constructed and comfortable to use. Overall, the Supernova showcases exceptional build quality and design.

Comfort and Fit

The Supernova's medium-sized shell fits snugly in my ears, thanks to its ergonomic inner shell design. Noise isolation is notably effective, providing a secure fit. I opted to use Azla SednaEarfitLight with the 7th Acoustics Supernova for added comfort.

Sound Quality

My listening setup with the 7th Acoustics Supernova comprises a MacBook Air/iPhone 12 + Apple Music + Questyle M15 + stock cables with 4.4mm + Azla SednaEarfitLight Eartips. From the outset, the Supernova delivers a smooth overall tuning with excellent midrange, crisp and musical treble, balanced bass with a broad soundstage, and precise imaging.

Bass: The Supernova’s bass is soothing and balanced, with a faster and rumbly response. However, it lacks in quantity, leaving some listeners, like myself, longing for a bit more physical body and weight, akin to thumping bass. Nonetheless, it maintains decent extension and texture, contributing to an overall enjoyable listening experience.

Midrange: The vocals on the Supernova are finely tuned, offering a hint of warmth and presenting a clean and clear sound. The fast and neutral tonality enhances the listening experience, making it feel as though the artist is performing right in front of you. The texture, weight, and body of the vocals are skillfully rendered, with the midrange positioned slightly forward relative to the bass frequencies.

Treble: Once again, the Supernova excels in the treble section, delivering smooth, detailed, and musical highs with a realistic tonality. It offers a sibilance-free listening experience, expertly avoiding any offensive peaks. The treble tuning feels safe and well-calibrated, ensuring an enjoyable listening session without harshness.

Soundstage & Imaging: The Supernova boasts a wide soundstage with ample width and depth, providing an immersive listening experience. However, the imaging capabilities are average, leaving room for improvement in pinpointing the precise placement of sound elements within the stereo field.
