Bluetooth Bone Conduction Open-ear Headphones Subversion X (JR-X1)
Most people are familiar with standard headphones and know extraordinarily little about bone conduction headphones. The key to understanding bone conduction headphones is to familiarize yourself with how sound travel into our inner ear (cochlea).
Bone conduction headphones exploit this theory by transmitting sound through a different path to the ear. It sends vibrations through the bones in your face to the temporal bone. This temporal bone is the bone surrounding the cochlea.
The vibration of the temporal bone causes the cochlear fluid to move, which in turn sends signals down to the auditory cortex where the sound is heard.
These headphones are made for outdoor or indoor sports use. The IPX4 waterproof rating makes the bone conduction headphones resistant to light rain and able to stand up to sweat. The headphones are lightweight but highly durable with a comfortable fit. This is made possible with it’s memory titanium alloy build. The soft gel on the earpad ensures long usage without discomfort.
The on-ear controls divide tasks on 1 side, with a touch control area for controlling playback, call management, and summoning your mobile device’s voice assistant. All of these actions are handled with various taps or holds for a few seconds. There are also some phone-specific controls that can be utilized such as “-” and “+” physical keys for volume and forward/previous tracks.
The best part of this headphone is the wearing outside the ear which maintains the perception of surround sound making it clean and safe. Using latest black technology it accurately project sound to specific areas on a specific directional experience.
Subversion X battery life is estimated to be roughly 6 hours, with 10 days standby time.
Internally, a built-in electric speaker deliver a frequency range of 20Hz-20kHz. On tracks with intense sub-bass content, like U2’s “With or without you,” the earphones have strong low-frequency depth. At top, unwise listening levels, the bass doesn’t distort, and at more reasonable volumes, the low-frequency response is still quite palpable and decently matched with the highs.
“Two Steps Behind” by Def Leppard, a track with far less deep bass in the mix, gives us a better sense of the Subversion X general sound signature. The drums on this track get some added bass boosting, pushing them into near-thunderous territory, but stopping just shy of it. Callahan’s baritone vocals get a nice, rich low-mid presence, matched with solid definition in the high-mids. The acoustic guitar strums and the higher-register percussive hits are bright and crisp, and even the tape hiss takes a slight step forward in the mix. In other words, this is a sculpted, boosted, but balanced sound signature.
On Chris Media’s “What are words,” the kick drum loop receives plenty of high-mid presence, allowing its attack to maintain its punchy edge, while the vinyl crackle and hiss that are typically in the background get pushed forward. The sub-bass synth hits that punctuate the beat are delivered with serious depth—we’ve certainly heard deeper bass boosting on this track, but Subversion X definitely doesn’t shy away from the lows. Luckily, the deep lows are balanced with crisp high-mids and highs. The vocal performances are delivered with excellent clarity, but perhaps a bit of added sibilant.
