Comfort
Putting on the headset without extending the strap I found a little tight, though after adjusting it a few clicks the squeeze eased and on my head was a headset that is pretty comfortable indeed. Soft earpads and cushions on the headstrap work very well and long gaming stints are not a bother and is good for those who wear glasses too. There is a little ear warmth build up but nothing too bad as PU leather is breathable so it isn't likely to be an issue unless you sit in a hot unventilated room, then you may not want to use a headset ever.
Design and Durability
The bold glossy coloured aesthetic is a matter of customer preference. The plastic is tough and durable and should survive those accidental falls that can happen once in a while. Plastic is used on the adjustment straps too, though they are strong, they may wear and slip over time. The braided cable is a good touch which gives strength and protection to the cable.
Inline controller is mounted upside-down?
Interestingly, both the stereo and v7.1 versions of the Tunguska has the inline controller mounted upside down, resulting in a little confusion when sliding your hand down the cable and your thumb ends up sitting at the base of the controller. Moving your thumb back down do the volume dial on the stereo version, rolling the dial down results in volume increase, and rolling up turned the volume down. To rectify this, you must pick up the inline controller and orientated it correctly while fighting with the braided cable in hand to which at this point you are dead in game.
Moving on to the v7.1 inline controller, again upside down and back to front, aside that issue there are bigger issues. Firstly the plastic seems significantly lower quality to the stereo version as it feels fairly flimsy and fragile, secondly, though there is a 'power on LED', there is NO functional LED indicators as to when you have muted audio or microphone. Considering that the inline is mounted incorrectly where the volume up is in the bottom left, volume down in the bottom right, it may be fairly common for a user to accidentally hit the mute or mute mic button. It may be fairly obvious to when you have muted the audio, but not so much when you mute the mic and it may take 15-20 minutes or so to realise that noone in your conversation is replying to you because you muted your mic by accident and there is no indicator to tell you otherwise.
These are clear design errors that I hope can be fixed.
Music
Tunguska 2.0
General listening showed a nice balance of bass and mids while high mids to high tones were crisp and clear. Turning up the volume causes a little distortion, though unlikely to have an effect as it only sets in at a level many may consider to be uncomfortably loud. Playing through Alcest-Sur l'océan couleur de fer, the guitars sounded sharp and the vocals were enchanting. Listening to The Dropkick Murphys-The Legend of Finn MacCumhail was surprisingly fun and there was a distinct clarity between the bass lead drums and vocals. It has become evident that the Tunguska 2.0 headset can deliver some enjoyable and well rounded audio performance.
Tunguska v7.1
The USB version (strangely sounded better with the virtual 7.1 enabled) has a more balanced audio and was enjoyable to listen to various music genres. The audio quality is good though could potentially be out performed by the Tunguska 2.0 on a decent sound card. Bass was slightly weaker than the 2.0 and the treble slightly less crisp though overall no real complaints. No distortion was discovered at max volume, though the volume was limited to a 'reasonable' loudness.
It is worth noting that there was only a small amount of sound leakage from all versions of the Tunguska headset range.
Games
Tunguska 2.0
In DOTA 2 the stereo sound worked well and I was able to notice distinct noises such as someone using a salve off screen clearly as well as sounds made by unique abilities being activated in the middle of team fights. Playing through various other games and the Tunguska 2.0 delivers some good quality audio, in particular, the pronounced trebles really added great effect in battlefield 3 as glass broke and bullets hit metal you are hiding behind.
Tunguska v7.1
The v7.1 USB version had an enjoyable experience in game though the virtual surround was slightly confusing at times as I found that it was difficult to distinguish between sounds in front and sounds from behind, fortunately the visual display aided in identifying sources. Overall the gaming experience was good and should give a decent improvement to most who are using integrated audio solutions on their motherboard.
Microphone/Conversation
The microphone on both works well and is well positioned to clearly pick up voice without picking up your nostril jet stream too. Though they did tend to pick up a little background noise, it wasn't too bad and was nowhere near as distracting as some.
An issue discovered on the v7.1 USB version was that if you set the microphone sensitivity below 50% an electrical chirping and beeping was picked up to all those in conversation, and was then dispelled when increased to over 50%. this appeared to be a USB issue, otherwise the microphone performance was fine.
