The headphone jack is an input, not output, odd design..my bad for not catching it.

bummed, didn't catch that the headphone jack is really an input? That is crazy...will have to return it and get a DOT. The sound is ok but that isn't what I wanted it for, I want to be able to play through other speakers. It setup really easy, and Alexa understands me just fine. Pretty cool integration with maps and drive times.

The Q has a mini-usb socket, but doesn't support headphones in it!!

Hi, I received this N9000 Android phone 2 days ago. I tried to plug in my Bose headphone to this N9000 to listen music. But the N9000's headphone jack (earphone port) is recessed deeply and causes the headphone connection loose. I have tried my Sony headphone and got the same connection problem.  I cannot use any headphone with this N9000. I am very disappointed with this faulty design. I have searched the web and found that there was no adapter available for this kind of recessed headphone jack. Another problem of this N9000 is that its Bluetooth sound quality is terrible and bad for some old Bluetooth stereo headsets (e.g. 2007 made). This means you need to upgrade your Bluetooth headset too if you have old Bluetooth headsets. Buyers should be aware about this problem before buying.

The base/part with the logo below the jack is too big to fit into most bluetooth-accessible headphones, so they are pretty much useless for headphones. However, if your car as an aux accessible plug-in, this would be great.

.. Because, with this cable plugged in,the headphone jack and speaker is disabled.  I guess that's a side effect of it being a DOCK cable.  If that's ok with you,  this is a good cable.  Just don't expect to be able to hear sound while charging unless you are actually docking to some speaker setup.

The actually quality of the materials of this item is pretty good.
That said, the connection areas are poorly designed, IMO.
I looked at this part of the audio jack again, and I can see that the way the case is designed does indeed protect the jack interface. so the interface works well with straight headphones inputs. The Apple ones that come with the iTouch I got holds the jack securely, but angled ones have a hard time going in and connecting. The sync cable input fits, but the hard cover itself kind of covers the input so it makes it a little harder to unplug when combined with the soft cover. The third thing is related to the on/off button on the top of my iTouch 4 player is recessed just enough to make it a chore to simply turn on or off, if you use it that is.
Please note, this was my experience only. Maybe other covers may be different.

I can see why the manufacturer discontinued it,  my Boys and I can't hear any sounds from the headphone it self. I just haven't call Amazon because I don't have the box it came in with.

I was satisfied until I learned there's no standard headphones audio output.  How is this possible for any TV manufactured within the last few years?  This is a very sophisticated piece of technology, yet it's missing the most basic standard way of connecting any sort of speakers or headphones. Some companies just still don't get it when it comes to building things that people actually want.

UPDATE:
So I was mad when I first realized there was no audio output.  After writing this review, I bought an optical audio to analog converter and have since been able to use it with a pair of computer speakers I bought.  I still think it's kind of dumb that it's not an industry standard to include an analog audio jack, but overall I must say this TV was a good purchase.

I was using this with my PS4 headphones and it worked like it was suppose to. I recently went a different route though so I'm not using it. Nothing wrong with it though.

Headphones are pretty good.  Sound is clean and crisp.  One drawback is that the jack is quite big and has a weird angle to them.  (See Pic)  It tends to get disconnected when I have it plugged into my Iphone 6 and stuffed in my front pocket.

I will say that the sound is nice, but for some reason the jack just did not seat well into my mp3 player.  It is like the plastic molding around the prong expanded a few millimeters to far up the prong for it to fully lock in to the female. Not enough for it to fall back out, but enough to notice the lack of a full insertion if you compare it to another model. I had a lot of crackling and ultimately had to secure it in place with Electrical tape, similar to if the MP3 player has a loose female port.  It does not, it works fine with multiple other headphones so it is the headphones that are bad.

I was going to give this a 3 star rating and say sometime you get unlucky and get that 1 in a million bad one.  With the amount of "tinny Sound" complaints that I am seeing here I am just going bottom shelf and make the jump to the idea that this is a design flaw or poor manufacturing and say avoid at all cost.

I was 100% buying this when i saw reviews of this online. But when i got the item was amazon the audio jack was acting up. It wasn't working as intended. If you're wanting to buy this for the audio jack, i suggest not. The sound however that picks up is amazing. Just really bumbed out that the audio jack was working...

When did Apple start shortening the headphone cord?  It's hard to use because its so short. You'll have to go ahead and buy another one, so plan on that added cost.

I am quite disappointed in this case. This is mainly because the space for the headphone jack is not large enough for me to plug in my headphones. What is the point of having a case on it if you. Red to take it off to use a set of headphones!

It's well built and solid. I've had mine for going on a decade. No worse for the year. But what is it for? Well, it's a fancy unpowered audio splitter and/or mixer. I use mine to take one sound output from my computer and control 2 sets of speakers, a bluetooth transmitter, and/or headphones.

But the sound loss (attenuation, I see it's called) is real. Well, here's what I've figured out: any signal that goes between any of the channels is cut down to a low but consistent level. There's no power plug, right? That's a plus. But what goes in, sound wise, is all that can come out. And though what comes out is *less* sound output, it is also *consistent* sound output. And that's not bad. Moving the sliders or plugging and unplugging things doesn't change the volume on the other channels at all, as it would if you used a simple cable audio splitter (at a fraction of the price). Here, the output is constant (though always low) no matter what you do.

As to the extent of the sound less, if I plug my headphones into my computer, I might have the computer volume set at 17%. If I run my headphones through this and set the slider to max, the headphone volume is lower even when the computer volume is set to 100%! That's a big difference. As another review says, takes the cons seriously. But if you connect to anything that is powered (as in, you plug it in) and amplifies the sound you're fine. But the sound loss is large enough that it does not work well with anything that doesn't have its own power supply, which probably means headphones or little self-powered speakers. At least not with any output I can get from my computer.

Here is my headphone workaround: Each channel has two sockets, one 1/4" and one 1/8". Plug the headphones into the same channel as the input signal. Then you get full volume (albeit without slider volume control). Sure, you could plug your headphones directly into your computer, but for whatever reason (distance, convenience, or lack of multiple audio outputs) you bought this so you don't have to.

There are five independent audio channels, four with a slider control and a fifth on the back. Since the mixer can be used in either or all directions -- and this is where things get fun -- you can use the 10 sockets in almost any input/output combination you want. 6 inputs and 4 outputs or 1 inputs and 9 outputs. You're only limited by the fact the sockets are paired (and different sizes) and there are only 4 volume sliders. And also by the fact that signals coming out will be weaker (much weaker) than the signal coming in.

The 3.5 mm jack was too short to fit into my headphone jack. It didn't click in and would just fall out. It looks like there is a spacer at the base but it cannot be removed.

its a good pair of headphones if all you have on your phone is a usb cable port and no regular headphone port. its pretty much your only option if you want to listen to your mp3s. they sound descent but i wish i could use regular headphones. i would have to buy an extra extension in order to do that. it also sucks that you cant use them for anything else. also, don't lose them, because its not that easy to just find another pair in your house somewhere.
