Makes cheap earbuds sound great.

I spent weeks searching for a product that would allow me to wear a decent pair of in ear earbuds that can isolate sound for me but also offer decent noise reduction for the caller on the other end of the line

Sound is perfect-I am using my favorite older set of wired bose earbuds.

Most devices, like those over-the-neck devices have great sound for music, but the other person ALWAYS complains they can't hear me clearly, I'm muffled, echo, etc.

I like the fact that when connecting it has a soft sound, unlike others that blow your eardrums out

The sound is great and the time frame of battery life really impressed

When I did get it to play the Bluetooth streaming is terrible sounding, sounds 10X better plugging in your phone straight to the aux

Works well decent sound and amplification.

BUT THE SOUND IS STILL AWESOME

Sound is clear they do go out quick not durable you will have to continue to replace them

It ends up with a very good quality sound (dependent on your headphones of course).

Voice calls sounds not so good

The connection goes in and out and there is an audible annoying sound each time it loses and reconnects.

This is my third bluetooth of this type and by far this is the best sounding and the best quality one that I've

Voices are clear and understandable but somewhat tinny sounding

The sound is good

After a few hours I got it to connect to my work HP elitebook for a few minutes, but the sound was so bad it was like a 1990's VoIP call - AT BEST

The sound is great (as the headphone plugged into it)

The speakers I bought with it not are very good, I did plug it into other speakers around the house and it produced good loud sound

The sound is awesome and uninterrupted

Good overall sound except for the bass which is very thin.

I have a very good Parrot headset for communication but finding a good sounding, proper fitting and long wearing set for music has not been so easy

Of course wired connection is still the best sound out there, but for this bluetooth device, it still makes my headphones sound great.

Sound is fine when the connection is stable, which is rarely.

The sound is decent, but it's just not robust enough to have "rich sound".

Lasts a full day at work, good clean sound

Luckily I found this device that I had low expectations of to satisfy my need for good sound quality and my mind was blown away on how well the sound stayed intact and the loudness they produced

Sound is fantastic!

If I plug the same headphones directly into my phone, the sound is great, but I don't hear the same low notes when using the Jumbl.

Good sound and battery life.

So whenever you have some low-intensity sound for example one folder opening sound on windows PC (i hope you will be aware of this typical sound), it is not able to produce that sound and will just create one annoying cracking sound

I was worried about the sound quality with sine of the reviews, but it's better than my $149 LG tones with harmon kardon sound.

Works great sound wise

With my Bose earbuds the sound is great

Basses get a little weak once the Jumbl is in the loop, but otherwise the sound is great

Sound is not any worse than the original chips.

Also, the stereo sound is great

Phone stays in pocket, wired to helmet speakers and the sound is as good as it gets

First rate sound, easy to use, takes a charge and holds it and more than other blue tooth items, the mic is very clear in conversation

Sound is great!

Very good sound though the connectivity cuts out after 100' or so

The battery life is good and the sound is good also

The sound is clear, music plays with good bass, mid-range and treble at middle to louder volumes

It syncs with my phone really easy, and the sound is great

The sound from this is very good and I have not had any problems with it

The sound is great and gives you range to walk around

It works fantastically great sound and mic

I have walked as much as 15ft from the music playing device and still have clear sound, no interruptions.

The product worked great and had surprisingly good sound

Well made, great sound, and easy to use controls

Terrible sound

Works good sound is also good fits in your pocket and picks up Bluetooth from a distance, pleased with it

Easy to use, good quality sound and now I'm not tethered to my iphone/ipad.

I have Bluetooth headsets, but I love stereo sound so this is a gift.

The sound was good when it did work but cant enjoy it when it keeps dropping.

It has great range, great sound, great battery life, and is very small

ft (no line-of-sight, there are obstacles between the unit and my iPhone at my desk).I've used it with multiple earbud headphones and the sound is great
