Forward words:
First, I would like to thank Audio Geek's founder,
@deep2285 , BGVP, and USA tour administrator , for allowing me to audition for the BGVP Phantom (
http://en.bgvp-hifi.com/product/info/41) link to the products are mentioned for pricing and specifications.
Disclosure:
I want to clarify that I'm not a reviewer; I've been active in the audio community and was fortunate to be invited to join the Audio Geek. So, in other words, you're getting impressions from my time with the Phantom and humble sonic knowledge with decades of music listening and multiple in-ear monitor flight hours.
Physicality:
Looks are great; they appear to be wood but are resin with thermic properties:
Their size is small to medium, their fit is comfortable for long listening sessions, and their isolation is excellent. I had no issue with their nozzle and used Penon orange tips.
Hardware:
I only used the original cable with a 3.5mm termination, iBasso DX180 for sources, and a KAEI TAP2 amp in Tube mode at high gain.
Sound:
It is balanced with mid-high focus; it has a U-shape.
The Bass has texture but does not layer or go as deep as I would like. It's speedy with minor decay. Its focus is more on the sub-bass than the mid-bass; I would describe it as fast-clean.
The Mids are forward-center and very natural-sounding. The tone and timber are some of the best I've heard. Male or female, voices are lifelike and a pleasure to listen to.
The treble extends gracefully, delivering detail and shimmer without being harsh. The "air" in the higher frequencies adds an ethereal quality to the soundstage, enhancing spatial perception. This balance between richness and smoothness will cater to those who seek detail without the fatigue associated with overly bright tuning.
Staging and imaging are impressive and immersive. Wide, tall, and deep. It's the best three-dimensional-sounding in-ear monitor I've heard.
Conclusion:
I've been living with the Phantom for over a week and a half, although I've been swamped and have listened less than I would like. They have caused a pleasurable impression.
I would describe the Phantom as a three-dimensional, natural, and transparent-sounding in-ear monitor.
