Hey all. I finally tore myself away from Halo 3 to write this for you guys. Thanks to KBI and electr0n for all the help and guidance. On to the impressions!
I'll start with the JVC Surround Sound adapter since many of you are looking for a AC adapter solution.
Amazing little guy. Was way smaller than I expected. Fits in my hand. But
WOW! what sound. It delivers a really convincing 5.1 surround sound experience. There are 3 Dolby headphone settings. To me the main difference between them is that each new level adds more reverb/echo/delay as if your space is getting larger and larger. Setting 2 sounds like a moderately sized living room 5.1 system and Setting 3 sounds like toward the middle of a movie theater. I think if you are a gamer, you'll find Setting 1 most beneficial, because the sound is a bit flatter and its easier to distinguish the direction of incoming sound. I perfer Setting 2 for my movies. I watched V for Vendetta while testing. The Bailey Building explosion scene and the conference scene directly after was were I tested the different sound settings. Nucking futs! And don't get me started about Halo 3. No spoilers I promise, but the sound is incredible and you owe yourself a similar setup. I did briefly run into so popping and silence issue on my unit, but that disappeared when a reconnected the optical wire to my 360. The cable I used doesn't give a great secure connection. Anything else I say about the sound per say I think will be more a reflection on my headphones (more on those later), and the optical output than the adapter itself. So I move on to the AC adapter mod.
First, use these links
Most of what I did I found on that page. So I'm really just going to post pics, and talk about parts specific to the JVC adapter. Feel free to ask questions.
One quick note. I found this mod an absolute necessity. I do not have an unlimited battery supply, and this thing sucks them dry in no time. I did not go two hours before draining the set that came with my JVC. Not awesome for all night gaming sessions.To the pics!
The Radioshack adapter:
You won't get a spark crossing the AC adapter wires at only 3V, so use a volt meter.
The mod completed:
Clips to JVC:
Clips to AC:
After this I had to do some extra work to get the wires out of the adapter while keeping the cover on. (Fire risk? Dunno but definitely not worth finding out.) So basically after I secured the clips to the JVC I cut some groves out on the battery cover. Sorry for the blurry pic.
Battery Cover Grooves:
Cover on, Wires out:
Last note, connecting the positive alligator clip to the JVC was a pain since I was trying to pull the flat coil out then clip it directly to it. No dice. I suggest find a twisty tie, stripping the paper, and cut off a third of it. Then slip it through the coil vertically with a very small flathead screw driver. Then just bend the remainder out toward the battery bay and use your clip. Finito.
Good to go:
Whew. That took longer than expected, so I will put up my impressions on the Senn HD555 up later. Short Version: Tremendous sound, awesome with the JVC, and go get some now. But if you can wait, I will also put up some pics of the entire setup, HDTV and all. Take it easy, gents.
