Headphones / Headsets / Microphones

[Quadcaster]

Hi,

I recently bought a pair of H600 headphones for wireless gaming and music. I got them home and was extremely disapointed with the sound quality. Sound is AWEFUL! I plug them into my computer and the sounds are all distorted, with music being unlistenable (have also tried girlfriends laptop, no dice there either!).

I decided to try it via bluetooth pairing with my iphone. I was insanely surprised: SOUNDS PERFECT! Best headphones I have ever used to listen to music, sounds amazing. Yet plugging into the USB dongle (and a bluetooth dongle I purchased as an alternative, thinking the logitech dongle was perhaps just rubbish) into computers sounds aweful.

Why do you think this might be? Is it just a faulty headset? Is this just a poorly designed unit? What do you make of the difference between aweful quality with computers, but excellent quality when BT-ed to my iphone?

Thanks in advance.

Hi,

I bought h800 and I have same problem... I thought I was the only one and was thinking of returning headset. Using integrated Bluetooth in my laptop seems to work excellent on other hand...
I even went that far to test distance I could use headphones...
With USB I can barely go to other room; with Bluetooth I can go to neighbors apartment without problems

But I would like to know why using nano receiver makes so much distortions? Is it hardware or software?

For a month now I have been playing with these and tested them. Sound comparison was made h800(dongle mode), h800(bluetooth mode). As of my audio-listening experience I used Logitech Digital Precision PC Gaming Headset for over 5 years at least. Also, for sound sample was taken first 15 seconds of AC/DC-EvilWalks.mp3 (320kbps, 44100 kHz; Channels: Stereo; Encoded with: MusicMatch) since I found sound distortion quite obvious in that sample.

Operating system used is genuine Windows7 Pro 64-bit  with all latest updates. As of bluetooth driver,  2.1, 2.0, 1.1, 1.0 Bluetooth versions are supported and work flawlessly. Tests on other computers show same problems.

Here are problems I noticed on my H800:

1)H800 connected via USB dongle

-static-like distortion of sound is so bad that it is unbearable to listen anything (games, music, movies,...) except IM services (also obvious under Speaker settings -> Advanced -> Default Format -> 16bit 48000Hz -> Test; and btw I can't manage to change test frequency...)

-inserting dongle into USB2.0, 3.0 slots doesn't have any effect

-changing options in Audio device doesn't resolve the distortion issue

-uninstalling/installing USB drivers doesn't have any effect

-in speaker properties under Enhancements option Loudness Equalization helps a TINY BIT but still not enough

2)H800 connected via Bluetooth

-no distortion of sound; BUT sound levels of left and right earphone are not leveled up (right earcup is mostly more loud then left one) so stereo is unbalanced

-manual balancing of sound levels can partially fix the problem because once you turn volume up or down, balance messes up again

-you can't use stereo headset with microphone at the same time (it's either headset mode or handsfree mode)

Now, I really wish to see how can I solve this? I really don't care in which mode I use headphones (dongle or USB), I just want to have normal sound without distortions (don't even need mic)... For headphones of 100$ (100€ in my country) I think I don't ask much do I?

I was thinking of returning them, but if so many people have same problems (not only with h800, but h600 and other wireless) I think either we are all doing something wrong or drivers in headphones are so bad and faulty that should be returned (which I doubt that company as Logitech would let in production a faulty product design)

Tech guy help?

I have noticed some issues as well, and I have a couple theories.

• The battery on the dongle only lasts 2~3 hours at most before i get crackling
• When connected to the USB cable + dongle the clarity is fine, until the unit becomes fully charged - then I get crackling again.  I unplug the USB cable, listen for 2~3 hours clearly, and then repeat
• I find the sound quality via Bluetooth much better, and the range much better as well
• I have not tested Bluetooth long enough to know the duration of the charge or if the crackling whilst connected to the USB cable on a full charge has the same behavior as the dongle
• I don't notice a sound imabalance via Bluetooth as someone mentioned - my levels seem fine

Overall I really like this product.  I wish the battery life was longer but I will test via Bluetooth and maybe this is better.

same problem here.. disappointed by Logitech... i will buy their keyboards but never anything else.. why would a product be released without being properly tested..

I wish I read this before I bought the H800....

Crackling unbearable when connected to my new iMac (late 2012).

If no solution found, I will return it for refund.

Crackling drives me bonkers.. Very disappointed with my Logitech product.. The H800 is a deal breaker for me. Same issue on my desktop with win 7 then win8 and also my laptop.
Whats frustrating is it works perfectly when you least expect it.
I think it is an audio codec issue. I need to spend some time testing and making note of what crackles as not all files do.

Logitech = bad joke.

Bought one H600. Unbearable distortion. Returned it. New one - same problem. 

OK - surely a software problem. Ran the pairing program. No change.

Looked at the Logitech website. FAQ of course completely unhelpful.

Tried to contact Logitech. No email address which could be used to ask them a question.

Can this be serious? Is this what they call support?

The users are allowed to help each other though, wow, what a service. But even for that you have to provide all kinds of data including address and telephone number?

CAN THIS BE SERIOUS? Selling a faulty product, not being available in any way for help and then requiring multitude of personal data only to be able to ask a question from other users? 

This is surreal.

I will return this second headset as well and avoid Logitech for the rest of my life.

I'm also having the exact same problem with the h800 logitech headphone, having awful distortions when using with USB dongle.

What I'm seeing here is that there are many people here posting the same issue, and still see no answer from a logitech representant with a solution, nor in any website I can find in Google.

Consider that:

- I have no wireless interference

- No obstacles between the headphone and the usb dongle.

- This happens to me in all computers I have tested onto, and is happening to many users, meaning that this seems not to be hardware related, but directly related to this product.

- Tried un USB 2.0 and 3.0

- Tried a clean boot

- Tried tweaking all I could from the Control Panel -> sound section

- Tried rebooting with all services from msconfig disabled

- Many users have received a replacement headphone but this issue persists, so that this does not seem to be a solution

I paid for this and want to enjoy this product. I kindly ask you to abstain from leaving this thread unattended and provide us a solution to this issue so we can enjoy the invested money.

Thank you.
