When an original music source is compressed, Sony's Digital Sound Enhancement Engine faithfully restores music to high-quality sound that’s closer to the original recording.

Crystal clear calling

Precise Voice Pickup technology optimally controls multiple microphones and performs advanced voice signal processing that allows the person on the other end of calls to hear you clearly, even through noisy surroundings.

Great linkbuds
These are the coolest most tech earbuds I’ve ever seen! You can set up 360 degree sound which literally makes it like a concert! The sound is great and I’m highly impressed with the quality of these!! They are really easy to set up and you can even download an app to adjust the settings!

Amazing technology make this a must have
These are the only in ear buds that I have owned that do not hurt my ears and can wear hours at a time. I have tried ALL the other ones. I like the fact they are NOT noise canceling I like being able to hear around me working outside. The sound from music on these does a great job of drowning out the noise anyways. If you ever had issues wearing in ear ear buds give these a try! I LOVE them

Great earbuds
The holes worked for me. Great sound at the same time not isolated from outside world. Phone calls are surprisingly clear. Comfortable to wear for long time.

I was initially drawn to how interesting the design looks and the color, but when wearing them they are very uncomfortable. The whole thing is hard plastic, Including the area that sits in your ears. It felt low quality, but the battery lasted a while and was easy to charge. Its only good for short periods of time.

Nice design
The design aspect is different and nice, however I feel the sound quality is lacking. Packaging was minimal and a great way to reduce waste of extra paper packaging. The charging case is compact and has a quality feel. Sound falls flat and Bluetooth connection is unstable quite often.

Great features
LinkBuds Truly Wireless Earbuds Are a good addition to my everyday events. I’m able to use them hands free for music and to answer phone calls. It come with instructions to put them in your ear and different size rubber pieces to fit any size ear. Very easy to install all you have to do it scan an QR code and the app pops up and you connect to blue tooth and you can use right away. Once charged they last about 5 and a half hours at full charge. I would definitely recommend these to all my family and friends.

My new best friends:)
These Sony Linkbuds are Ahhhmazing! Crystal clear sound, connect effortlessly to my Galaxy phone and stay connected until I disconnect when needed, fit comfortably and securely with no ear irritation at all.
This is the first time I've ever seen the open end, I'm used to the buds you jam in your ear canal and before that the big bulky headphones that make your head itch. I'm really enjoying the Linkbuds because my ear canal is open, no worrying about germs or yuck being pushed into my ear, BUT also the freedom of hearing what is going on around me without messing around taking them out. And being able to tap on my cheekbone or any area around the ear is so much easier than tapping the traditional buds I normally used, no loosening or knocking them out and onto the floor for the cats to play with lol.
Finally and I can't express this around in the app! Do the ear analysis for proper fit and wing tip size, before I changed tips I didn't hear the bass as strong and they just didn't sound and great as I was expecting BUT once I found the analysis and saw I needed a smaller wing tip(super easy to swap out the included various sized ones) I seriously experienced the concert quality I crave. Even though the other tip fit well it wasn't "right" take the time to truly get it right before thinking these are subpar for Sony standard. Oh and also in the app you have so many customizable settings, equalizer, presets, bass boosting, the surround optimizer, your music apps, seriously so many things you can personalize to rock your world- literally.
I honestly didn't think I would enjoy this style of buds because seriously I like blocking out the world with music, but these actually do give me that escape when I turn the volume up to mind deafening levels...and they still stay crystal clear!
Truly a game changer in this boomer's listening life :)
