V9 Bone Conduction Wireless Headphones Review – Ticking Timebomb?

Welcome to a review on the V9 Bone Conductive Earphones. Yep, bone conductive earphones sure is a new technology when compared to the “traditional” in-ear headphones. These gadgets only caught my attention when a random ad popped up on my Android phone.

My first thoughts were – Cool. These should be much safer than the traditional ones when jogging on the streets, and bone conduction technology is just like some sort of sci-fi movie. But sadly, a pair of these “branded” bone conductive earphones easily cost above USD 100.

As an “experienced techie”, my gut feeling tells me to not splurge on rather experimental technologies and regret later. So I did some digging on “affordable alternatives”, and here it is. Is the “unbranded” cheapo V9 worth the money? Read on!

Possibly a ticking time bomb, buy at your own risk.




The Packaging Build & Design Sound Quality
Battery & Wireless Summary & More Not Worthy



Mix “affordable” and “Made in China” together – This combination rarely gives an impression of quality. Truthfully, I wasn’t expecting too much, but the V9 actually came in pretty decent.



It’s a box with shrink wrap! Yep, I was expecting a pair of $30 earphones to come in “raw bubble wrap”, but this is quite a pleasant surprise. Even though the design is simple, a sealed unopened box adds a lot to the “quality factor”.



There are no “gold cards” nor “VIP stuff” inside the box. But it is simple and has all the basics.

  • The earphones themselves.
  • Instruction manual in English and Chinese.
  • Micro USB charging cable.
  • Foam earplugs.




First impressions and packaging aside, the earpiece itself is actually not too bad either.



The V9 pretty much just looks like any other Bluetooth earpiece neckband. I personally don’t think it looks bad, but it does not have that “classy designer touch” either. It simply just works… Also, the V9 is offered in other colors – Black, white, red, pink.



There are no official websites and specs for the V9, but some online sellers dare to claim this as a “titanium build”. I really doubt so with the price point, but here’s what I can tell from the “feel” of the actual earphones themselves – Hard plastics and rubber. Yep, forget the BS of those dubious online sellers.

There is no titanium, but the V9 still has a respectable all-around quality and is solid nonetheless. The simple, no-cables design also made it more rugged. So long as you don’t abuse it, slam it against the wall, run over it with a truck, or put it under a hydraulic press – It will survive long enough.



The controls are all on the right side of the earphones, from the left to right:

  • Micro-USB charging port.
  • Tiny little LED indicator.
  • Volume down button.
  • Volume up/power button.

Nope, those “circles” do nothing, probably hidden screws below. Also, the right earpiece is touch-sensitive. Tap twice to play/stop, long tap to bring up SIRI/Google Assistant.




Some online sellers claim the V9 to be “waterproof”, but I highly doubt so again. I can’t find an official website nor specs for the V9, but judging from the design – Water can surely get into the tiny buttons, USB port, and earpiece itself. Don’t use the V9 for watersports, it is “water-resistant” at best.



Comfortable to wear for long periods. Fits snug, and it will not drop off easily – Even when doing rigorous exercises, running, and jumping around.



After a couple of months of usage, the V9 simply refuses to power on. Tried a couple of tricks with it:

  • Long press the power button.
  • Press both power and volume buttons.
  • Thought the battery went flat. Tried charging, but wouldn’t even budge – No lights, nothing.
  • Tried searching on the Internet for more information, only turns out that quite a lot of people also encountered the same problem.

It’s probably a busted circuit board or dead battery, and I contacted the seller to ask for a return. Which, of course, got ignored. So I took the next best course of action, update this review and warn others of a potential ticking time bomb.



The overall packaging and build quality of the V9 is actually decent… But the part that may be a turn off for most people – They don’t sound great at all.



The V9 is my first pair of bone conduction earphones at the time of writing, and I don’t have a good comparison of the sound quality. Also, it is kind of difficult to fully explain the sound quality in words, but here goes:

  • Lows: Lame pops. Kind of expected, having a sub-woofer vibrating against the bone will be quite scary anyway.
  • Mids: The only ok-ish range, guess vocals are still the one that this earphone tries to do best at.
  • Highs: Nope.
  • Clarity: Slightly pronounced sharpness. Kind of made my ears bleed a little.

In short, this thing just sounds like a small speaker playing beside the ears. Audiophiles – Don’t ever buy this pair of earphones. It is not made for enjoying music, but “having sound while keeping an open ear”.



The V9 never gets too loud, but still audible nonetheless. At the higher volumes, the earbuds start to tingle against the skin and the audio leaks. Yes, the person right beside will be able to hear… But that is also the same for loud headphones.

To be fair on the audio quality, this is a different technology than “the usual”. Put on the earplugs, and the audio does sound a little bit better. But that kind of beats the point though, these earphones are meant to keep an open ear while playing.




For this final section, let us walk through the “boring” battery and wireless.



The battery is rated at 180 mAH, which is just about the same as other “regular Bluetooth earpieces”. But here’s the thing… It only lasts about 5+ hours as compared to 10+ hours. But personally, I am not really bothered nor turned off by the short battery life.

The “bone conduction drivers” are different technology, and probably uses a lot more power than conventional in-ears. Also, who exercises for 5 hours straight? Even so, 5 hours is enough to run an entire marathon.



This is the part that I really don’t understand. Micro USB? 5V 500mA at this age? This thing charges slowly by today’s standard. 2 hours from zero to full, and only to last for 5 hours. I mean, how much will a USB-C fast charge upgrade cost?



Nothing to complain about. Bluetooth 5, stable, and no problems. Works well within the distance of an unblocked room.




Finally, here is the V9 Bone Conduction earphones in a nutshell.



  • Main control chip: CSR8635
  • Battery type: 180mAh polymer
  • Frequency response range: 20HZ-20KHZ
  • Charging voltage: DC-5V 500mA
  • Charging type: Micro-USB
  • Playtime: About 5-6 hours
  • Standby time: 10 days (240 h)
  • Charging time: About 2 hours
  • Size:19.3*13.2*6.5cm
  • Bare metal weight: 37g



  • Only costs a fraction of the “branded ones”.
  • Water-resistant, can survive sweat and light rain.
  • Well built and solid.
  • Lightweight, snug fit. Does not drop off easily, even when running and exercising.



  • Sub-par audio quality when compared to “traditional in-ear headphones”.
  • Audio leaks at higher volume levels, plus uncomfortable tingling.
  • Bad battery life, slow charging.
  • Bad build quality – Either the battery or circuits went bust after a few months.



The V9 is definitely not some “sci-fi miracle bone conduction earphones”, and it has various shortcomings – Sound leaks at higher volume, poor battery life, slow charging, sub-par sound quality. But I am sure that other “good brands” face some problems with bone conduction technology as well.

However, the biggest flaw of the V9 is going bust just after a couple of months, the build quality is also seemingly sub-par. So personally, I am still going to give the V9 a thumbs down – This is a potential time bomb, buy at your own risk.

Thank you for reading, and we have come to the end of this review. I hope that this has helped you to a better choice, and if you have anything to share with this review, please feel free to comment below. Good luck and happy shopping!

  1. Thumbs down. Wore maybe a dozen times and now they will not power on. Volume was very weak but okay for biking.

  2. These are crappy headphones a crappy company and i dont believe for a second that they even care about the product they just send it out and move on . Ive been trying for a month to get someone to reply to my email after they said the would “check their warehouse” yeah right get out of here they font have a warehouse because the company is a fraud.
    I paid 40.00 with tax and it said a three year warranty. Thats a joke .
    Letting my friends and family and anyone i know who is thinking of buying these to stay away from these yahoos.

  3. I’ve had my V9 bone conductors for over a year I think 15 months and have never had a problem. I walk 3 x a week with them generally at the beach, so different types of noise. I do however listen to more podcasts than music. I found them due to not liking “normal ear phones” that I have to stick in my ears, so for me these are brilliant. I also like that they are flexible and don’t annoy me by hanging on my ears. I think my only dislike is they are marginally too big for my head, but I have a small head – so that’s my fault! Overall for me they are brilliant I would have no problem in recommending them.

  4. I bought these trash your phones I don’t think your review is very honest For 1 thing it’s hard to hook them up Wirelessly It takes forever and yes I know what the hell I’m doing another thing They stopped working after a couple of months I start looking at reviews and everyone is having this problem they work for a month or 2 and then they stop working Don’t buy these they’re not worth it Try to get my return or you can help And they just blow you off They’re trash

    1. Please mind your manners and temper, also grammar and sentence construction. No need to throw tantrums and hissy fits at people who didn’t suffer the same bad experience – It’s pointless and only served to paint a picture of “snowflake”, “Karen”, and “strawberry”.

      Been using the v9 for a little over a month now, had no issues with the Bluetooth connection so far (paired with Redmi Note 8 Pro). Bad parts as mentioned – Audio quality and charging time isn’t good, build quality is “shady titanium”. But see the published date above, I have not used it for “more than a couple of months”. We shall see if it lasts. Chill.
