The battery life is good and the sound is good also

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.

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

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

Terrible sound

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

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

The sound is good

Also, the stereo sound is great

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

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

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

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

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

Good sound and battery life

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

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

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

Voice calls sounds not so good

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

The sound is awesome and uninterrupted

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

Lasts a full day at work, good clean sound

Sound is great!

BUT THE SOUND IS STILL AWESOME

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

It works fantastically great sound and mic

Works well decent sound and amplification.

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

Works great sound wise

Works great sound wise

The sound is great and gives you range to walk around

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

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

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.

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

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

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

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

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

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

With my Bose earbuds the sound is great

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

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

Well made, great sound, and easy to use controls

Voices are clear and understandable but somewhat tinny sounding

Makes cheap earbuds sound great.

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.

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

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

Sound is not any worse than the original chips.

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

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

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

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!

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

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
