What customers say about "Key Specs"
Sony HT-CT770 2.1 Channel 330W Sound Bar with Wireless Subwoofer
  • Plenty of volumn and great low end response with surprisingly clear midrange.
  • Great sound and response I love it. It also has 3 HDMI inputs for all my devices which allows for a single feed/return to my TV.
  • It is a very powerful system, has very good low and high frequency and ok mid frequency.
  • The sound bar is low and sleek, unobtrusive. It was easy for my non-techy husband to set up. The sound is powerful and clear.
  • Purchased this yesterday at a local Big box store. The manual sucks to begin with. The bass response is extremely weak.
Sony HT-CT780 2.1 Channel Sound Bar with Wireless Subwoofer Bundle
  • It has better frequency response than I was expecting, although it is pretty metallic in the high registers, and a little shouty in the midrange.
  • The frequency response curve that makes dialogue easy to discern also emphasizes awkward parts of the range for classical, jazz, pop, rock, electronic.
  • Bass response is okay, again it would behoove someone seeking real power to look for a more powerful system.
  • Expected sound to be more powerful but I guess additional voice clarity was the tradeoff.
  • This has more power and overall fullness. It lacks that "rounded edge" in sound if you know what I mean (which exists in Klipsch) so it's a little sharp.

What customers say about "Size & Weight"
Sony HT-CT770 2.1 Channel 330W Sound Bar with Wireless Subwoofer
  • Amazing sound for such a compact size. The ideal weight makes it 100 times better than other soundbar.
  • The size and shape is perfect for placing in front of the TV.
  • Perfectly located in front of my TV, compact and beautiful.
  • Perfect for a smaller size room. Great sound.
  • It's heavy out of the box and you might need help moving it around.
Sony HT-CT780 2.1 Channel Sound Bar with Wireless Subwoofer Bundle
  • Due to its size and design this unit has good stereo imaging, which was a very pleasant surprise.
  • This sound bar is great - beautiful sound and easy set up! I have a 65" TV and it is perfect size.
  • This is the smallest sound system I have had installed and I am very happy with it.
  • The sound bar itself could be more compact and not so long.
  • The box has an awkward shape due to the sound bar. The box could be heavy for some so you might need additional help lifting the box.

What customers say about "Features"
Sony HT-CT770 2.1 Channel 330W Sound Bar with Wireless Subwoofer
  • Easy to install and great sound. The remote has a variety of choices and settings that adapt to all types of viewings and DVDs.
  • Easily installed and set up. Very good sound quality. Integrates with TV and Cable remote without difficulty.
  • This product was very easy to install and to use. The Bluetooth synched with my iPod and even my Time Warner DVR remote recognized the soundbar automatically.
  • Really enhanced the sound from our tvs. Allows us to stream soft music from an iPad or iPhone when we have dinner guests.
  • Installation on the wall was very difficult. It is quite heavy and constantly pulled fastenings from the wall.
Sony HT-CT780 2.1 Channel Sound Bar with Wireless Subwoofer Bundle
  • It is very easy to install. Once it is plugged in with my TV, it works immediately.
  • This is a really good product. It was easy to install. Quality clear sound, and it can get as loud as we want it.
  • This bar sound great, look great on the wall below my flat screen, and was very easy to install.
  • It enhances the hearability for most of my use cases. Sometimes it can still be a little hard to understand, but definitely an improvement.
  • Great sound, easy to install, but a quirk with random volume increase that has eluded resets and support from Sony support.

What customers say about "Connectivity"
Sony HT-CT770 2.1 Channel 330W Sound Bar with Wireless Subwoofer
  • I plugged in the optical cable to my TV, applied power to the sound bar and the sub and everything worked!
  • Connects via Bluetooth to my old Droid, and has an aux for connecting non-bluetooth MP3 players.
  • Great unit! HDMI feedback to the TV is a little Squirrelly, but that is just gravy in my book.
  • The wireless subwoofer literally just connected after plugging it into the electrical outlet.
  • Only problem was the connection to the 5-year old Sony TV. It took a lot of trying to finally make the right connections.
Sony HT-CT780 2.1 Channel Sound Bar with Wireless Subwoofer Bundle
  • I love the HDMI connection with ARC. It's like one cable does it all thing.
  • It's inputs and ARC connection provide an ideal connection for all hardware.
  • The wireless subwoofer works well, I have it hidden under some furniture on the other side of the room, it connect automatically without issue.
  • Well done. Oh, except that the TOSLINK port seems to confuse it, so it likes to randomly switch back to the TV input when fired up, if you've got optical connected.
  • Optical output showed significant audio lag. Although HDMI is the way to go so this shouldn't be a problem. No lag over HDMI so far.
