There would be a periodic crackle indicating the connection was being lost.

the blue tooth breaks up and cuts out when it's in my pocket... less than a meter away... and it's looses connection if you're 10 feet away... tried with multiple devices with the same results... also the microphone sucks when you're making calls, even with the phone literally touching the head set... pretty much garbage for what they claim its capable of

Overall, I returned the headset based on non existent bass, poor Bluetooth connection and the large size.

If I am working on the computer or have one of the phones exposed on the table the connection would work as long as I didn't make a single movement and phone stayed completely stationary

However... The problems arise when they lose connection

My new pair does not have bad bluetooth connection whatsoever

I often get an intermittent connection when only a couple feet away from the receiver

I really like how comfortable they are, however they seem to have difficulty maintaining a steady Bluetooth connection with some of my devices (i.e. laptop).

I have received Two of these terrible headphones which lack the most basic requirement for a set of blue-tooth headphones, a decent blue-tooth connection completely full of noise, static and loss of signal.

Bluetooth” environment for optimal playback by turning off other electronics that can interrupt the Bluetooth connection

The Bluetooth function works fine when your head is near your device, but the E7s don't have a very strong connection to the device

Also, while wearing these and having my phone in my pocket (less than 3 feet of separation, it seemed the connection wasn't stable.

Additionally, there appears to be an issue with a loose connection in the right headphone

Pairing with phone was easy but connection was horrible

The headphones do not like to stay paired and although BT dialog showed "Connected" on my Win10 PC, there was no connection

Wired, these headphones have a solid, consistent connection

My complaint about this product is that I cant hear 1 music without a faulty connection seating on the chair less than 3 feet away

Sometimes though if you hold your phone at certain angles, can lose the connectivity and frazzle your connection

For some reason when I'm connected wirelessly to the head phones as I'm listening to anything it always seems to loose connection with whatever it is connected to, it skips in and out of connection while streaming music

The first pair I bought had a horrible bluetooth connection

Can't walk 10 ft away from my phone without its staticking or losing connection

Broken bluetooth connections.

Walked outside to do an errand and did not loose connection even though I was over 30 meters from My tablet

Also, if I put my phone in my pocket, I lose connection completely

otherwise it cuts in and out frequently and sometimes totally loses connection

The Cowin E-7 feel more comfortable to my head but not entirely comfortable (I can wear them up to 2-3 hours straight before I feel pain to my ears).They sound terrible not only compared to my Stanton but also compared to my cheap AKG earbuds

Have no problem with cowin E- 7

These E-7's are outstanding

n’t lost connectivity once.
