There was a problem filtering reviews right now. Please try again later.
The sound stage is overall very neutral. They hit at all the right spots for my taste. The mids sound great...you can hear all the little details. Treble errs a little bit on the bright side, but not overly so...Still neutral without being at all muddy. Bass is where the magic happens (for me). I cannot stand headphones that boost the bass, and these definitely keep things in BALANCE. The lows sound solid throughout, but if you have your volume turned up too high you might get some artifacting with the deepest lows. If you're looking for some heavy bass, these are not the earbuds for you.
Genre I've found that sound the absolute best - Classic Rock (Queen sounds amazing), Alternative, Classical or Instrumental, and Oldies. They just sound fantastic...rich and clean. Everything you want. Rap sounds decent, but remember the bass isn't going to blow you away. Industrial and Metal sound really good, but the deep lows aren't what I would expect. IDM/Techno/Dubstep is going to sound pretty mellow. I don't listen to country, so I can't say how it sounds....
Battery life is exactly what the box claims. After the initial charge I went from 100% to roughly 76% after six hours of almost non-stop use. After three days of testing, I'm getting fairly consistent results. Six hours = About 25% battery used. The case seems to hold a really good charge, too. I charged it once on arrival and it is still showing full after three nights of re-charging the earbuds. Not shabby at all. I'm extremely impressed as they blow the other BT sets I've got out of the water with their longevity. Also...Welcome to 2019....These charge using USB-C. NICE.
I've completely abandoned my wired headphones now, and I had just bought a USB-C DAC to use them with my iPad. These are just so much more convenient, and the sound is very much comparable.
I love that these automatically connect to the last device they were paired with. That was kind of a shock at first, so just know it happens. Haha. I ended up having to reset my connection because I didn't know and I un-paired using the buttons.
Two things to note: There is no volume control on the earbuds, and they don't come with memory foam tips. I will definitely be getting some of those in the near future.

Of course, my mind immediately jumped to Bose, Beats, Apple, etc. but I wasn't quite ready to drop that kind of money on a luxury, not a necessity. My search continued until I found this EarFun brand. 1. The price was in my range. 2. It offered wireless charging. 3. It advertised an impressive battery life. 4. It claimed to be waterproof. So I ordered these earbuds and gave them a try.
I have tested these for a few weeks under various conditions and circumstances, including work, soccer practices, yard work, house work, etc. To say I was pleased would be an understatement. Every test I gave these earbuds exceeded my expectations. In addition to providing excellent audio, they also helped tune out outside noise. I couldn't hear my lawnmower. I couldn't hear screaming kids at practice. I couldn't hear my annoying coworkers. Now, it didn't make all these activities something that I would seek out, but it did make them more bearable.
In addition to great sound and noise-cancelling effects, I liked the range on these earbuds. I could play an audiobook on my smartphone and, if I needed to keep it plugged in and charging, I could walk away into the other room and it would still be clear audio. All these great features though, and my favorite feature is the battery life. In addition to the earbuds themselves having a long battery life, the case also allows charging on the go, because it can hold 24 hours worth of charge, which is amazing! In a nutshell, if you are looking for quality earbuds at a fair price, I recommend you give these a try! I plan on buying a second pair for my wife!

*SNUG FIT- I do a lot of walking, climbing up and down scaffolds, and crawling in and out of tight drums which requires many different positions and I have yet to have one fall out of my ears!
*BATTERY LIFE- honestly I use one at a time more than both due to having to hear and communicate. I have yet to have either one die on me. I charge the case about every 3 days for about 1.5hrs.
*SOUND QUALITY- my previous everyday earbuds were the over the ear beats with the wire combining them. These are every bit as good as those. Bass, mids, lows it's all there! They also do pretty good at noise reduction.
*CONNECTIVITY- they turn on as soon as you pull them out of the case and by the time you have them inserted in your ear they are connected.
*CALLING QUALITY- phone calls and video calls work perfectly! I travel for work, so I video call my wife everyday and have never had an issue. Works perfectly with single earbud or both.
*TOUCH SENSITIVITY- earbud touch sensor is great. If I had to compare it, I would say it reacts the same as touching your phone screen. You can touch it lightly and it responds, or you can be in a rush and just reach up and slap it with a finger and it responds.
I'm not an easy person to please on products. Way TOO many companies over hype and misrepresent their products now. I'm always skeptical to buy products online due to that but these have been perfect for me.
Also, don't judge my pictures, haha. I know I need a haircut!😂 And I used the prescription bottle as a comparison because I feel like everyone knows what size that is. Hopefully this review helps someone that is as much of a skeptic as I am. 🤘🤘

Top reviews from other countries

The button controls work extremely well and have a good feel, not a hard press, just a nice click with enough resistance to avoid accidental pushes and but not so hard you push the earbud into your ear, spot on. You get skip forward/back, volume up/down, answer/end call, your assistant (Google in my case), play and pause, everything you need.
Battery life has been excellent, at 50% volume they went just over six hours and recharged in the case in about and hour and a half.
I'm delighted and honestly quite surprised. For the money they're excellent, even for more money they'd be excellent.
The big test for me is always, if I lost them or something happened to them would I buy them again? Yes, definitely. Have an amazing day.

It's frustrating that it happens and if you are not carrying the box I guess your mono until you get back the wherever the box is. Quite disappointing. So not the five star product I thought it was. Shame :-(
Original review below:-
I bought these to use while running on my treadmill. I've used them a couple of times now and found them to be easy to use. They connected to my bluetooth and reconnected automatically when they were used next time. The sound quality is fine (i'm no expert) volume is ok. comfort is good and they have not come close to falling out while i'm using them. The box they store and charge in is really good. I can't tell you how long the battery lasts but they still show full charge ofter over an hour of use.
So for me this is a five star product.

I take it to the gym. Does the job.
Compatible with my USB C cables. Awesome
Wireless charging. Awesome. I don't even have a wireless charger. used a friend's. it's there when I need it.
I charge it about once every other week. that's twice a month.
its waterproof they said. haven't tried it but no problems with sweat so far when I'm in the gym. (only buds are waterproof)
Sound quality? I'm not an expert but it's GREAT for me. earphones are definitely better, don't expect these to compete with bigger sound drivers, for example, Bose headphones.
Sound Volume? I don't even put in on Max. Two clicks bellow Max volume is good for me. Depends where you are and the environment you are in. I've been on a train, and they sound great still.
No touch controls? I don't mind. Pauses with a one click and volume increases with two. Right bud volume up, Left bud volume down.
Microphone? the only trade off that mattered for me. Do I use them for calls in a busy environment? nope. Do I use them for calls at my office? yes. house? yes. less busy environments? yes.
Fit is great. charge speed is great. what else?
I BOUGHT THESE FOR $50 months ago. NUFF SAID.


Bass + treble well balanced. After few months of use the right earbud stopped working so tried troubleshooting provided by seller. Still did not work so seller provided great customer service and arranged a free new pair.
Because of sellers kind gesture i have recommended 7 people to this great company Earfun UK keep up the great work. All the best.
