Question: Do any of these models have a headphone jack?
Document: Buy it, any of their models. Great sound and is the technology I was looking for. Simply put, it is the sound section your TV manufacturer left out.
I got this for my husband for Christmas and he loves it! You can place a larger TV on it (some of these have a weight limit so we couldn't put a 48&#34; TV on top). I really like the digital display that &#34;appears&#34; on the face of the box when you change the loudness - it makes it easier to see what you are doing. A lot of models did not have this feature.
I was looking to improve the audio of my tiny/tinny TV speakers (40" Samsung LED) without taking a lot of space. I liked the included sub-woofer idea sine I would not have to find a separate place for it. I emailed ZVOX customer support for advice and they were terrific, explaining the feature benefits and differences between models.
It was just ok, not great. I bought for the DE, but that was a joke. The sound was just ok. I really don't see how it got such good ratings by others. The remote pickup was recessed too far so you couldn't adjust the volume from an angle. The regular cable channels worked with the optical cable, but not the HD ones and I couldn't change my TV to give me the output I needed to make it work. I wound up using the phono jack output.
Pros: Louder sound for the TV masses. It's a LOUD BOX folks!Cons: Rear firing speaker disperses sound through walls into neighbors Apt. or other rooms.Uneven sound regardless of how it is set.Output leveling doesn't work for &#34;jack&#34;.Dumb &#34;simple&#34; remote that hijacks normal TV functions unless using ZVOX only. No learning codes provided.Why does it even have a digital input as it doesn't process the signal efficiency?
more expensive) speakers+receiver. At least this is what I will do.
i have some hearing loss and was having trouble with dialog clearness. i had already bought two soundbar systems and thequality of dialog was not good enough for me. zvox was recommended to me by a best buy associate and so i bought one onthe net. this zvox system reproduced dialog very good and i would recommend it to any one with or without hearing loss.
i bought this because i didn&#8217;t have room for a full surround sound system. But it has definitely been worth every penny. The vocals come out clean and crisp, bass from music or movies are incredible. The only thing I would have done differently would have been to buy the ZVOX 555. (It has better specs)
finely I can hear my lg tv . the zvox allowes me to adjust the sounds base and treble while watching the program also it fits in the space I have under the t v. overall very pleased with this unit.
a great system for a great price. sure beats the TV's sound! truly great sound thats easy to hookup with out all the expense of a full 5.1 system.
Answer: Not the one I purchased
