This seller was amazingly helpful… I ordered the wrong item (well, the right item, but with the wrong firmware) and the seller was kind enough to cancel the transaction and offered to have me send him my item so he could find the correct ear it with the right matching firmware. I couldn’t have asked for a more generous offer from a seller. I can’t say enough good things.

Absolutely thrilled with this company. Provided great detail on the product I was interested in, followed up to be sure I was ordering the right version before they sent the item. The item was delivered promptly and well packaged. Then, after I got the product, I couldn’t get it to set up correctly. They went waaaaaaaaay out of their way to help me to get it working. Super highly recommended. Will shop with them again!!!!

I wear these earbuds all the time.
I bit the bullet and bought the Sonly Linkbuds S after using wired earbuds with my phone for the last 5-6 years. All the talk about ANC hissing and Bluetooth codecs that drop connection had scared me away for a long time. I had bought a few cheaper earbuds and was not impressed at all. I was also a proud audio enthusiast (not quite an audiophile) and was not ready to accept wireless earbuds since I could get much better sounding headphones for the same price. Now that I have wireless earbuds, I wear them on/off throughout the day and place them back in their case and into my pocket for a quick recharge. A single charge on Sony's case lasts me all-day and should be fine for most people as well. This brings me to the one big downside; this case cannot be charged wirelessly, which means you ...

Now that I have wireless earbuds, I wear them on/off throughout the day and place them back in their case and into my pocket for a quick recharge. A single charge on Sony's case lasts me all-day and should be fine for most people as well. This brings me to the one big downside; this case cannot be charged wirelessly, which means you will have to connect it to a USB cable, and the cable you are supplied with is only a few inches long. Another downside (or upside depending on how you see it) is that you need to download Sony's app to get the most out of these earbuds. I know not everyone will want to use features like an equalizer, speak-to-chat, and custom touch controls; if you do that's all here along with other features. Sony's noise cancelling feature they call "ambient sound control" is extremely effective at keeping sounds from your surrounding environment out of your ears and is a feature I use often. You can also setup tap controls to turn these features on and off. When someone talks to me, I can just tap my left earbud to turn ambient sound control off in order to hear them speak. There is also a talk-to-chat feature as I previously mentioned which pauses the track you're listening to and turns ambient sound control off when you speak. I like this feature a lot, but I found out while using it that I talk a lot to myself when I'm alone and it was not useful to me because of that. I can also pause/play a track with a tap on my right ear along with skip to the next track with a double-tap. You can setup your commands however you like though sound controls have to be on one earbud and feature controls on the other. The sound of these earbuds are great overall considering the customization you have with the equalizer and its presets. I have presets set for podcasts, for EDM, Classic/Alternative Rock, and for movies. Whatever your flavor is you can dial it in to suit your listening experience. It's not hi-fi and it definitely is compressed audio, but it still sounds great overall when you consider the usefulness of these earbuds. I give them 4 1/2 stars or a 9 our of 10.

They are subpar headphones The quality is good. The problem is the left earbud likes to turn off that on randomly. And even when I turn off all of the touch features on the earbuds they just like to automatically change from noise canceling to transparency mode which is really annoying and then whenever I go for my 13 mile runs they like to stop and play music very annoying earbuds. I wouldn’t recommend them Honestly.They are subpar headphones The quality is good. The problem is the left earbud likes to turn off that on randomly.

Best value for premium ANC at a reasonable price! (that I could find!)
These are a great earbud even at current retail... I just tested the new (clear) beats studiobuds+, and the airpods pro2 (yeah even on android)... and these were my over-all favorites, so I ordered these referbs and they were immaculate (and have a 2yr warranty).. Would buy again (in fact am trying to get a black pair for my sister!)

No sound out of left earbud. I reported this a week ago. I have tried the Bluetooth transmitter that other devices easily pair to. I’ve Messed with it for a week. Still only the right one pairs. Also there were no instructions. I had to go online. I should have read the fine print. No refunds of course.
