Amazon.com: Customer reviews: COWIN E7 PRO [2018 Upgraded] Active Noise Cancelling Headphone Bluetooth Headphones with Microphone Hi-Fi Deep Bass Wireless Headphones Over Ear 30H Playtime for Travel Work TV Computer Phone - Red
Microphone cut in and out. People on other end of call had a difficult time hearing me. The Bluetooth would cut out periodically. Even the wired connection would deliver static if you moved slightly. Poorly constructed. The sound quality was good but that was offset by the other problems.
UPDATE: COWIN sent me another pair of E7's to try after reading my review above. I told them since I returned the original E7 I had purchased Sennheiser PXC 550 Headphones and I will compare the two. Here is my very honest, objective review of the new E7 they sent:
I did extensive testing. First connecting the E7 with an iPhone 7 and then an Android Galaxy 8 Plus, result: The E7 call quality is still horrible. Everyone (5 different people) I spoke with said I sounded “fuzzy.” Then I had my wife use the headsets and call me...I too heard how poor the call quality was with her using both the iPhone and Galaxy. Then I changed to the Sennheiser PXC 550 to confirm the call quality was due to the E7 and not the phones; the call quality with the PXC 550 was crystal clear and I could be heard very clearly and distinctly using both the iPhone 7 and Android Galaxy 8 Plus by the same 5 people I called with the E7. Finally, I had my wife use the PXC 550 headphones and call me; I too heard that the call quality was MUCH BETTER by a significant factor as compared with the E7.
Regarding listening to music: The E7 was “fair”. The sound was “tinny”; not rich or full. I tested the E7 with music on an iPhone 7, Galaxy 8 Plus, iPAD and a MacBook Air. I replaced the E7 with the PXC 550 and the sound was deep, rich and very full. The difference was night and day.
Lastly, I tested the E7 with movies on a MAC and iPad…once again the sound was “tinny”. I didn’t have the scratching sounds like I did with the original pair of E7s but still the sound was not rich. This time the E7 Bluetooth did not disconnect like the original pair.
Bottom line: The E7 are useless for phone calls and marginal for music and movies. I would not recommend the E7s.
After 30 minutes of use, I recognized that the earpiece on these weren’t the most comfortable. But I decided to continue using them, to see if maybe I just needed to break them in. A couple of hours in, the left ear began making a faint crackling noise. I thought maybe it was the video I was watching at first, so I stopped the video, but the noise continued, and then an extremely loud feedback crack happened that felt like it almost blew my eardrum. It was awful. I guess I learned my lesson: you get what you pay for.
1.Sounds quality was all I wanted for Bluetooth. Nothing spectacular, but not awful. 2. Noise-canceling worked well unless you tapped an earbud and then you would hear a loud thump. Very annoying when you're on a plane and rest your head against the side or wear a hoodie. Rather jarring 3. If the battery is dead you cannot even use the analog input 4. Bluetooth is on by a switch which means there is no way to automatically turn off headphones 5. If the battery is low and you plug in the headphones you will keep getting the battery dying sounds until you turn them off for a while and let them charge up. 6. One of the drivers broke off completely at the swivel. There was no extraneous force, it seems like the plastic just popped out the socket and sheared off the lip designed to keep it in place.
I originally broke a non-pro and they were great and sent me a replacement which also broke. Then I got ANOTHER replacement which, guess what, broke. All within 3 months and each time I treated them more gently. This past one broke between me removing them to my neck and then placing them back on. There must be a fault in how the cups attach to the over-head band because it's ALWAYS in that same location. Could be a glue issue? I like them otherwise just tired of having broken headphones!
THE BATTERY AND SOUND ARE ACCEPTABLE, THE ITEGRITY OF THE ERPHONE IS UNACCEPTABLE, THE LEFT EARPHONE CAN'T STAY IN PLACE MAKING THE HEADPHONE NOT USABLE. THE HEADPHONE WAS DELIVERED ON JULY 3, 2018, THE TOTAL FEILURE WAS ON SEPTEMBER 19, 2018. IS THAT THE EXPECTED LIFE OF THE ITEM??? PLEASE LET ME KNOW YOUR COMMENTS. PFPEREZ.
I tried out 7 different pair of over-the-ear headphones before deciding on these. The sound quality, comfort and and noise cancelling for this price is too good to be true. It turns out that's because they are built cheaply. I've worn them every day for 2 months, and this morning the swivel above the left ear cup(that allows it turn turn 90 degrees) just snapped in half.
This is so close to being a perfect product, if only it was built stronger.
I purchase this to replace the mpow that i recently purchase. I just receive this headset today and was excited to have a try. When I first open this package it come with a nice hard case bag. Then I notice the headset color is different from the picture and I'm sure it will get dirty instantly. After few try adjustment of fitment and put on and try. The button is so hard to reach. The put the next songs and volume on the same button. Long press for volume up or down and tap is for next songs. This is very inconvenience and it will easily skip the songs. The sound quality not as I expected, for $100 bucks I would just get another mpow for replacement. Which is less bulky and more value.
Made of plastic that will explode if they hit the ground these are bad. the buttons on the side need to be pressed in-ward towards your ear which also cuts out the ANC. I have good hearing and found these way to quite when i wanted to rock out.
