"I currently own various sets of headphones from OneOdio. This being my 3rd pair I wasn't hesitant at all to get these and put them through their paces. I am pickier than your typical consumer so this review might be longer than what you normally read so please bare with me.

Design-4 stars
These are just as beautiful as most of the company's other headphones so there shouldn’t be concerns wondering if you will look like a dufus walking down the street or even on mass transit. They have the ability to fold into them which allows you to put them into the included bag which is very convenient. Another nice feature is the ability to have the ear cups fold down onto your chest instead of them facing up. The reason it’s a lot more comfortable to have the ear pads resting on your collar bone than the hard plastic covers of the opposite side. Also people won't be irritated by the music you might be listening to. The ear cups are very soft as well as the head band. These have really nice red stitching on the top of the headphones which also includes the branding. Finally inside the cups the left and right channels are very well labeled with an "L" and "R".
The few potential concerns that I see due to my experience with Oneodio's headphones are the folding joints. Like previous ones I own they tend to loosen over time, making it extremely irritating to keep them in the ready to wear position. There is no way to tighten these unless you feel the need to do slight surgery to these to possibly find a way to tighten them up. I currently display all of my headphones on headphone display racks. Unlike my other brands of headphones these could go into "flop" mode like my other OneOdio brand headphones. The second is the ear cup is a perfect circle and not oval like one of their other wireless models they sell. Mine and probably others like me have extended ear lobes, making it a task to have your ears sit comfortably within the headphones. It seems most headphone companies are going the oval route to cover all shapes and sizes of ears, but for some reason OneOdio decided to go with a completely round ear cup. These won't be my first choice when it comes to a grab and go for a walk type headphone.
Functionality-4 stars
When it comes to ease of use these are top notch. These headphones come with a minimalist approach when it comes to functionality. 3 buttons do it all with the multi-function button recessed making it easier to know the difference between it and the volume buttons. The multifunction button works for turning them on with a long press and the same to turn them off. You will get a chime with both off and on. While wearing them the UP volume button would the button closest to the back of your head the DOWN being closest to the front of your face. One thing to note, when reaching maximum volume you are greeted with a subtle bell tone which is nice change from other headphones I have used in the past. They also play the same role of next track and previous track as well. A new accessory that comes with these headphones is an included inline mic for people who want to use these for gaming on their PS4 and XBOX ONE as well as wired phone calls. The function button on the inline mic is only for answering and ending calls. There isn’t a way to mute yourself if you decide to use these for gaming; muting yourself on the phone would be done through the phone itself. Bluetooth connection is quick and seamless as well as the connection is very strong, distance can really depend on your surroundings.
The functionally of these headphones do also come with potential concerns to downright annoyances. The first being the extreme tactile feel of the volume buttons. They are SO loud when you are trying to change the volume. Furthermore, I was on a call with my wife and when I tried to increase the volume to hear her better. She commented that she heard EVERY click of the volume button, asked me to stop as it was hurting her ears each time I did so. Now I am not sure if that is just a defect in these headphones or not but I not being using these for phone calls in the near future. Speaking of the volume of these headphones they have a great balance of volume but for some odd reason OneOdio decided that every so often these need to reset the volume memory you had placed the last time you used them. I can say without a doubt that other manufactures like Mpow and Anker, this has never happened to me once. I have no idea why someone would want their volume reset to factory default for any reason when you can change it yourself if you feel the type of music your listening to requires it.

Sound-5 stars
One word describes these; AMAZING! The overall sounds of these are just incredible. These are really for the balanced sound enthusiast. Everything is so clear from the high highs to lows. Now I didn’t emphasize the low end because they just don’t hit the sub bass frequencies I love. I have tried these with all genres of music and where they just don’t do it for me is the BASS style music. Artists like DJ Magic Mike, Bass Patrol, Techmaster PEB, etc. These can’t seem to hit the really low notes like I am used to in a pair of Anker headphones that I own. Getting to the BASS I like requires a lot of adjustments to the EQ on whatever device you have them connected to but again this is what I see as a downside, to others this might not be an issue. This issue is from the basshead side of me and I know from the 100’s of reviews I have read on headphones this can be a concern to them as well. From others around me sound bleed doesn’t seem to be an issue with these either and I have listened to these at a rather healthy level!
There really isn’t any major issues or concerns I have with the sound they produce as this topic can be very subjective. It really all depends on what type of music you’re passionate about.

Battery and Misc -5 stars
OneOdio claims 30 hours of battery life, of course depending on what you listen, volume and for the length of time, that claim can be subjective. Due to all of testing and general use I felt I met or almost exceed that time frame so kudos to OneOdio. It comes with all of the accessories you need to use them at home or on the go of course except a charging block, and come who doesn’t have at least one of those. I do have to say it is awesome that they included the inline mic and I can understand why they did as most of if not all Bluetooth headphones are really bad at mic response when using them for phone calls. This accessory clears up all the issues people have making phone calls with Bluetooth headphones.
Over all these are some very stylish headphones, with great battery life and a very balance sound. Strong Bluetooth signal and I forgot to mention when registering with OneOdio they can extend your warranty by an additional year, how awesome is that?! Thanks for reading this entire review. I hope it was helpful as I have tried to find reviews as thorough and just come up short all the time.
Thanks!"

"I've had about 5+ headphones in the last year, from regular $30 ear buds, to Beats Flex buds ($50), to "gaming headsets", and even though most of them had fairly decent sound, their volume and bass-capability left a LOT to be desired. Not this set. I took a chance on this set, I knew it would be a good set considering the amount of high ratings, but I did not expect it to be as loud as they were. This is a good thing. Most sets seem to hit a volume peak of say a 9 or 10 and can't go higher, whereas this set goes all of the way to a 15. This is NOT hyperbole/exaggeration.

So if you are one of those people who despise the low volumes of most headsets and want it loud. If you have a problem with loudness, then it doesn't take a high IQ to figure out that you can lower the volume...duh. I'm 52 and have perfect hearing after listening to music since the 70s and having gone to 50+ concerts in all these years, I don't need some artificial babysitter to limit the loudness, I'm doing just fine.

Bottom line is that these are the best headphones that you can buy for around $30, hell even the sets that I have had that were $50-60 were no where near as good as these. If you want good bass and truly loud volume with no wimpy babysitting lameness, this is the headset for you. And the fact that it has a detachable cord that can be easily replaced is another star added to the mix. Everyone knows that the Achille's heal of a wired headset is the wire breaking after months of use, with either the right or left or both sides going out. This way you only have to spend 5-10 bucks to replace the wire. And the way this wire attaches to the headset I seriously doubt it will break anytime soon."

"I bought these to replace cheap Panasonic ear buds that I had been using interchangeably to listen to audio on my computer and phone. No, I'm obviously not an audiophile, but for this price the sound quality is as good as it gets. I am truly impressed. Better yet is the noise cancellation. I cannot hear my husband talking on the phone (or to me) when I have these things on. I liked them so much that when my wireless tv headphones started acting up, I decided to buy another pair of these. Yes, I had to get an extension cable, but the superior sound quality plus the added bonus of not having to worry about battery charge more than makes up for the minor inconvenience of being tethered to my TV."
