Suddenly no sound :-(

By Henrik

from Denmark

Comments about JBL Cinema Home Theater Soundbar System:

I seem to have the same problem as many others, the soundbar just went dead. I have tried to reset like you describe with no luck. The soundbar has been a joy to listen to but this issue with lost sound give your product one star.

Only issue for me is Bluetooth control

By DHBurton

from Atlanta, GA, United States

Comments about JBL Cinema Home Theater Soundbar System:

Bought it a couple of years ago so it stands up well over time. Only issue for me is a can't seem to find a way to switch it to Bluetooth remotely. Sucks having to walk to the unit and press the button to activate Bluetooth. Am I missing something?


TERRIBLE repair service

By JohnMM

from Adelaide

Comments about JBL Cinema Home Theater Soundbar System:

This sound bar sounds fantastic for the price, but unfortunately it WILL ONLY LAST FOR 1 YEAR Then, after it breaks, you will take it for repair under warranty, and a component will be changed then it will last for another 1 YEAR Then, after the exact same component breaks again, you will suddenly find yourself with no support since your warranty has expired, since the distributor is curiously unwilling to recognise any warranty oblication related to the replaced part or repair service. Then you will start reading online and realize that the product lasts for 1 year not just for you.. but for almost EVERYONE. There is a fundamental design fault in the circuit board, it is not fit for purpose and will almost always fail after 1 year. The repair that you receive is not really a repair, it's just a bandaid - since the design fault itself will not get corrected, you'll just get a new version of the SAME faulty part


Great audio, but no Bluetooth wireless security

By rybu

from Seattle, WA, United States

Comments about JBL Cinema Home Theater Soundbar System:

I bought the soundbar about two years ago. The sound quality is great, and has the same JBL sound that I know and love. I would give it 5 stars, except the soundbar has a critical flaw. You can stream to the soundbar via Bluetooth, but there is no security on this Bluetooth. No needing to press a button, no password, nothing. This means that you will be pranked by your neighbors at 3am in the morning with loud rap music. Let me be clear: there is NO WAY that you can stop others from connecting to the sound bar. Even if you turn it off, others can connect and turn it back on. You have to physically unplug the soundbar from the outlet. I've owned other non-wireless JBL products and have been quite pleased. However, this is a deal breaker for me -- not just for the speakers, but for the brand itself. Currently looking at other soundbars with Bluetooth security. JBL engineers: This is not something you can ignore. I feel like I deserve my money back, especially given the premium price I paid for this.

it's simply awesome

By Jazzmuffin

from South Lake Tahoe, CA, United States

Comments about JBL Cinema Home Theater Soundbar System:

My house is small and my surround system was finely giving me trouble after all these years so I needed to do something. I decided to give this soundbar and sub a try despite some not so great reviews. I started off having some issues with my wifi once I hooked everything up and realized I was running too may things on a 2.4 frequency but since I have a duel frequency router, I moved everything I could to the 5 and no more issues. The sound is crisp and clear and I have no problems with the connection to the sub but believe I would have if I kept everything on 2.4. I'm thrilled that it has Bluetooth and so many HDMI connections so I have more options. JBL has never let me down in quality and value and this soundbar is no exception. Over all, just a few adjustments for me and my world is full of ear pleasing sound and worth every bit of the effort and purchase price.


Sub will not pair

By Mike Bee

from Portland, OR, United States

Comments about JBL Cinema Home Theater Soundbar System:

Just bought the unit(s) yesterday, and am disappointed that the sub will not pair, or stay pair to the sound bar. Can anyone help me prove that I am the problem and not the unit? I followed the instructions, but the light on the sub stays Orange, and does not emit any sound. Please help?


Great sound, but not very durable; expensive

By truth777

from Philippines

Comments about JBL Cinema Home Theater Soundbar System:

i owned one at home for the past 2 years and was seldomly used...it had a great sound along with the subwoofer...but the soundbar got busted easily..no light indicators even if it was plugged to an electrical source...even thought it has an amazing sound, the price isn't worth it..the electrical repair shop here in the Philippines is also too far and hardly accessible if you are from the provincial areas..Is there only one repair shop of jbl here in the Philippines?


Sub-Woofer Cutting Out!!

By Mhanix

from Philippines

Comments about JBL Cinema Home Theater Soundbar System:

I intermittently get this problem and it got worse today. Searching through the internet, I came upon a comment from a certain Sinuhe to the JBL site citing working wi-fi as the culprit. I was actually streaming Music Videos through my smart tv and projecting audio to my SB400. My son was also actively using wi-fi looking at his youtube favorites. When I switched off the wi-fi and played music on my iphone connected via bluetooth to the SB400 (to test Sinuhe's findings), voila! The problem went away. What's the fix here??!! You cannot live without wi-fi nowadays. This is a frustrating problem for an otherwise great audio system!!
