Only negative thing is that Siri on the iPhone is very difficult to control as the main button would be used, but holding too long shuts it off, too short pause/plays the music.

So good that out of 2 $300 pair of headphones I decided to cut and shorten the wiring by almost 2 feet on one pair, soldered a gold 3.5 headphone jack professionally this way I don't have all the loose wiring all over me, I love it and every thing about it

This product is great, only thing I dislike about the product is the connectivity issues it has

So far, this thing has been great

I love this little thing now that I charged it the second time

The only negative thing I've noticed is that the bass definitely clipped

This little guy is a really nice thing to have, with my HD429s headphones

This is a fantastic little thing

This thing is excellent especially if you pair it with the Plugphones Workbuds

Loved this thing for snowboarding but lost it in the parking lot one day

I turned my phone sound down (using a different bluetooth set) and it didn't seem to help things get quieter, but I'll just change out earbuds to make it quiet enough for sleeping

The worst thing I ever bought it never works

Only thing I don't like is the inability to fast forward and reverse

this thing is fantastic, I have several now!

On the other hand, a couple things that it does really annoy me

I love this little thing, it's quite handy

On one hand, some things that it does really impress me

This is not a bad thing, just takes a little getting used to

I LOVE THIS THING

Only thing I don't like is the inability to fast forward and reverse

This thing is freaking

Love this thing.

I love this thing

This thing was awesome for a while but it stopped charging after only three weeks and never charged again

The nice thing about this one is that not only will it last the entire workday, but if it does run out, you can still play music while it recharges!

only thing that worried me was sound distortion but surprisingly the sound on Jumbl Bluetooth 4.0 sounded and still do amazingly, I couldn't tell the difference trying with the

Sad thing is

Loved this thing for snowboarding but lost it in the parking lot one day

Love this thing!

This things super cool if you're using it for a helmet, I pretty much cut the clip off and saded down the hump on the

This thing is great

I REALLY love this thing!

This thing is awesome, I use it to make my Bose QC25's wireless

This thing is awesome

I can't praise this thing enough!

That's where I realized this thing is crap

I would get the brighter color as these things are small and easy to lose track of.

I think this is my first review too so, shows you how frustrating the thing is to me.

That's a good thing though because it's not that they break easy or are unreliable, they're fantastic

This thing didn’t work Static and communication between my sounds (speakers) systems and

I love this thing

All I can say is that they all worked pretty good but none got close to the Jumbl 4.0 which partly because the 4.0 Bluetooth built in the controls worke perfect with the iPhone ( I mean, Start, stop, Volume up/down, Voice Calling, Forward and rewind, and even Siri if disconnecting voice calling in the phone settings which let you do a voice calling through Siri if you wish or many other things like playing a certain song as a small example of the possibilities )

I can't praise this thing enough!

I love this thing

The best thing I've purchased for my iPhone in quite some time.

I cannot believe how great this thing works.

this thing sucks

Awesome little thing

First of all, I want to say that I really wanted to like this thing

But this thing got washed AND dried and it still worked like the day I bought it

I love this thing
