Review: Battery lasts a long time! - I have so many different earbuds but I find myself returning to the single earbuds again and again, bc I like to be able to hear what's going on around me while listening to something. I'm fortunate that I can listen to stuff at work most of the time, but I also need to be able to quickly turn off whatever I'm listening to when someone is speaking to me, and I find that the double ear buds (even with "ambient sound" on) make that difficult. I bought this earbud after the one I had been using finally died after like 4 years of pretty much continuous use. I wasn't able to find the brand I had before, so I tried this one. The battery life is AMAZING. I usually put the earbud in at between 7 and 8 am and listen (on and off) to something for the whole day, into the late evening. I have not yet run out of battery on the first day - in fact, most of the time, the earbud is still at like 70% battery even after listening to it all day! I can use it for 2 days in a row without charging most of the time! It fits snugly in my ear and comes with several different tips so you can find the right one for you. Pairing is pretty easy and the on/off button is large so it's easy to press when I need to quickly turn it off. I don't love the micro USB charging, my last earbud had a magnetic base to charge on that I liked better, but it's okay, and the cap to the port tucks away nicely. Sound quality is fine, I mostly listen to podcasts/news so I'm not looking for a fantastic sound experience. If I'm listening to music, I go with the double earbuds anyway. It works well for phone calls, I haven't had anyone complain that they can't hear me clearly when using it for phone calls. All in all, it's a great single ear option if that's what you're looking for. EDIT 6 MONTHS LATER: My ear bud has died suddenly... It had a period of about a week where pressing the on button did nothing, but if I plugged it into the USB port briefly, it would come on, but now it's just dead... I don't think I overcharged it, I tried to let it get down to 10-15% before charging (or let it die completely - which as I said in my first review, would often take 2 days.) Not entirely sure what's happened with it... Up until it died, I really loved it, used it every day. I know I'm past the return window, but perhaps the company has some suggestions? Will try to contact them.
Review: LOOOONG battery charge, good sound, easy set-up - I LOVE these! I've paid a lot more for earbuds and just don't use them after getting these. I've bought several of these. I like to use single earbuds instead of pairs so I can listen to books or videos and still have full access to the ambient sounds around me. Volume is GREAT - I can hear my content while vacuuming! I also listen to music. I don't have a particular need for the perfect music sound; I'm a musician. The notes matter more to me. I don't expect the sound of a perfect concert or studio performance with perfect timbre from these earbuds. I'm here for the notes - for the counterpoint, the harmonies. So these are perfect for my needs. I like to play soothing sounds overnight for sleep, so the batteries are important to me. These last a shocking amount of time. Maybe 12-18 hours? I'm not sure - but it's a very, very long time. I get up in the morning and keep listening for hours. I should pay attention to the time. Because they are so cheap, it's not a catastrophe if you lose one. I have lots of different earbuds - these are the ones I use all the time.

## Questions & Answers

**Q: Does this have the flashing blue light? I want one with no light for listening at night.**
A: I hear you! I I've had the same problem. There is the usual pinpoint of red/blue light on the face of the device, which flashes only when pairing, & really is quite unobtrusive. I wear mine at night, & have never seen the light from this earbud, even in a very dark room.
This really is the best earbud I've purchased, out of 6 different types: longest battery, quick charge, fits either ear, & generally, no fussiness.
Peace, Friend

**Q: I just received this and it works fine but i don't see how to connect the usb charger cord. can someone help?**
A: Hi, At the buttom of the earphone, there is a little gap between the cover of the usb port and the product, use your nail to open it, and then you can connect it with usb cord. Note: usb cord can be used with charger adapter under voltage 5V, charging time is about 2 hrs (light from red  to blue/ off). If you are not clear about our words, could you give us your email, we could send you a video to show how to do it?

**Q: I am having trouble getting this to pair with my phone.  I have tried several times and made sure that the unit was in pairing mode.  Any ideas?**
A: To whom it may concern: 
You have to make sure the device is discoverable then to pair both make sure on the ear piece itself hold down the on/off button for at least 5 seconds before letting go of your finger. Or until your cellphone Bluetooth displays J18 then connect to it.

**Q: Is the output in stereo or mono for mp3 music? no one really answered this, and it doesn't say stereo in the description.**
A: Ear piece puts out sound for both left AND right in one ear so not stereo in the way it’s defined (different sounds in each ear) but you get all sounds. I tested it on a song that I knew had different sounds in each ear; I heard it all.

### ⭐⭐⭐⭐ 10 hours of play time is accurate
*by B***O on June 25, 2021*

this ear bud really does last at least 10 hours. It doesn’t nest as cleanly in the ear as smaller versions, but then size begets capacity. The flexible cover for the USB charge port was extremely difficult to re-seat after charging — it kept popping back out, so you really had to force it in place with a thumbnail. I finally just tore it off. I’m hoping this thing lasts a good long time because frankly a lot of the cheap commodity electronics / adaptors etc., that I order from Amazon are mostly junk that only last a few months. So far, this earbud is impressive. Aug 2022 update: I had to buy a replacement not because of a defect, but somehow I managed to bend the pins inside the charging socket. The newer one has some notable differences: voice prompts are a different and more refined voice; charging still is indicated by a red light, but the blue light that indicated a full charge is now gone - replaced with nothing (light off). Decent sound quality is the same and sometimes, adjusting the volume all the way down from your device does not silence the audio completely and it still seems to last AT LEAST 10 hours on a charge which is very impressive. Bluetooth connection notification is now voice instead of a beep, and connections are more competent: when you’re paired with more than one device, switching from one device to the other is cleaner, with no more audio overlap or cutout. Sep 2024 update: just in the past week, battery life dropped significantly from about 11-12 hours to less than 8. This is a problem for my application so a new one is on order. Two years may be the cutoff for this product with regard to battery life. Oct 2024 update: the unit will not charge sufficiently anymore, so it looks like 2 years was its maximum life. Just ordered a replacement. The $14 every 2 years won’t break the bank, but it’s still disappointing
