CVJ VVT-1
Dual-core Upgrade Ensures High-definition Transmission
The new upgrade starts from the "core"; VVT-1 utilizes the Qualcomm QCC5125 Bluetooth 5.3 chip + dual decoding chip ESS 9039Q2M high-energy combination. This setup provides stable high-definition audio transmission in various modes, effectively reducing distortion and noise, thus making the sound purer.
Restored Music Details
Sound-oriented. VVT-1 restores musical instruments and human voices to create high-fidelity, low-noise products. It achieves a mellow and dynamic sound, satisfying audiophiles' pursuit of distinct musical instrument sound sources.
Large-capacity Battery Lasts a Long Time
Built-in large-capacity lithium battery offers a longer service life, with about 7 hours of battery life under standard conditions and about 7 days of standby time. It supports power display and charging while in use. When the BTLINK flashes, it is in the waiting state, and a steady green light indicates that the connection is successful.
Lossless High-quality Music
Supports LDAC, SBC, AAC, aptX, aptX-Adaptive, aptX-LL, aptX-HD, aptX-Adaptive, LHDC, and other high-definition Bluetooth audio protocols.
Exquisite Luxury Materials
Aluminum alloy anode shell + laser engraving process. VVT-1 uses aluminum alloy as the shell material. The tempered glass panel can reduce electromagnetic interference. The shell anode not only prevents the oxidation of the aluminum alloy but also reduces resistance.
Excellent and High-energy Decoding of Sound Wave
The high-standard headphone output of dual OPA2107 brings delicate and mellow sound quality. The TPA6120A2 dedicated amplification chip delivers about 800mW of large thrust, while the noise floor is low and inaudible, even with high-sensitivity headphones, ensuring clean sound quality.

Customer Reviews
I bought this about 2 weeks ago and it takes a lot of learning to figure out how to make it sound its best. It needs to be turned up about ¾ of the way from full volume(I used the wired connection(usb c to usb c)) and your source(mine is android Samsung phone)) at very close to full volume. It comes with a usb a to usb c cable, so you may need to buy a usb c to usb c OTG cable to use it with you phone or specifically c to lightning if you use that type of apple phone. Then let it warm up for about 20 minutes to 40 minutes before actual listening like this and then still leaving like this or reducing to a more acceptable level to you where tone is still ok. It depends on the efficiency of your earphones or headphones. It has very good imaging and balance of all frequency levels. All instruments sound well represented and their presentation or location seem pretty fine to me. This a very nice device, way, way better than it's price should allow. I'm very impressed and satisfied and of course lucky to find this! I always end the day with listening to it, I can't go without listening to it what I mean. I don't believe it is missing anything in the sound quality spectrum. You just have to experiment with that volume control and bass switch(or leave the bass switch off for more natural sound) to coax it out of it, ask it nicely. Lol Oh and to experiment with source volume too. Be patient, it is such a great device! I have yet to try out Bluetooth, but it has the latest 5.3 and the best chip for it too, so I have the utmost faith in that being pretty fine too and I'm very anxious to try that too. If I can remember, I'll update how it goes. It is one very beautiful device with a great style, the front is a thick glass that shines greatly and looks so good and the back is a black with a lighter shade in kind of a checker board type of pattern that looks really good on it. For my listening I used the 4.4mm connection. There is also a 3.5mm which I did not use. The bass boost function is a nicely done boost and is spread across up through into some lower mids too, it is really nice.
Battery life is very good, don't let it run out to completely empty and they say to not let them charge to 100% and they'll last even longer in their overall lifespan. But this is good to it's specs.
Thank you so much Linsoul and CVJ!
