This thread at little-dot forum explains which gain setting to use to suit your headphones. Viewing a thread - Clarification on Setting Gain I prefer low gain with the HD650.To me, the high gain with the HD650 produced bloated bass with a bit wider soundstage when compared to low gain setting.

The tubes I got are definitely not 6n6p. I compare them with my old 6n6p today and the size is different. They are a bit longer than 6n6p.Also the letters on the tubes are not 6H6n. It says 6N1n-EB on the tubes. I have contacted the seller and sent some photos. He said he sent me wrong tubes...

I bought 4 6n6p-i from a seller name alexer1 from Ukraine and I got a package with 4 green boxes inside today. At the side of the boxes it says 6N1n-EB in Russian. Are these the same as 6n6p-i????

I game a lot with the HD650. Mostly FPS. IMO HD650 sounds very polite in FPS games. Everything trying too kill you sounds pleasant. No ear piercing bullet whistles or explosions. Everything is so smoooooth. It's almost like a picnic. That's why I use HD650 for gaming.

I had the same problem but switching the left/right HD650 cable connectors fixed it. In fact it's now slightly biased to the left a bit but still have better channel balance. Might be because of my left ear is damaged so the left bias is less noticeable.

Excuse me but will the kryptonite improve the sound? And it would be nice to change the inscription from Grado Professional Series to Grado Superman Series.

IEMs is probably more suitable than full-sized. It's troublesome to carry a pair of big and expensive headphones around while you can just put iems in your pocket. Noise isolation and leakage are better too.

Wow!! very good read. Looking forward to the next part.

I'd love to know what tubes are best for the HD650s , too. I've tried the Mullard M8161s and the 6ZH1P-EVs. While the M8161s are very detailed , they are a bit warm sounding making them not suitable for the HD650s in my opinion. The 6ZH1P-EVs have extensive high and low but not as detailed as...

My MKIII came with a pair of 6N6P or 6H6n (not 6N6P-I). I bought mine around April - May last year.

great review and nice pics!.

I went straight to the HD650s after the HD595s. If you drive the HD650s with your X-Fi you will notice better soundstage , more bass but bloaty and rolled of high compared to the HD595s. The bloat bass of the HD650s is really annoying without an amp. Amp under 300$ improve the HD595s but not...

Sennheiser HD650 Sennheiser HD595 Sennheiser PMX100 Sennheiser PC150 Sony MDR G54LP

I have both and I choose the HD595 for gaming. Gaming with HD650 is not very engaging at all especially shooters despite having better separation and soundstage. For everything else I choose the HD650.

I added and removed the K601 from the cart like 10 times. In the end I didn't buy it. That was really nice deal.

I spent my time with Little Country III for about 1.5 hour with HD650,HD600, MS2i in a shop 3 months ago. IMHO this amp pairs really well with Sennheiser but somehow not as great when pair with the MS2i. Pretty good for the price if you ask me.

I bought my pair at around the same price from Singapore 3 months ago. Great pics!. Those pics seem to capture the laid back signature of them very well. Nice review too!.

This is Penchum's opinion and ciphercomplete's opinion about the small shield and the large shield M8161. Hope it helps. Little Dot MKIII Tube Rolling - Page 111 - Head-Fi: Covering Headphones, Earphones and Portable Audio

Even with portable amp , my HD650 still sound better than my 50 ohms HD595 but not by much. So I guess that the HD600 will sound better than the HD555 with portable amp Your HD555 must be really sad considered you're going to dump them now. After all you seems to love the HD555 very much...

If you like the HD650 then go for it. You wont have to worry about upgrading your headphones anymore and can focus on other things like dac or amp. Even unamped the HD650 still sound very good to me. I really feel sorry that I didn't go for the HD650 at first. Now my other cans are collecting...

Well you should eat a lot when you're in Thailand. After all we are the kitchen of the world.(At least that's what we're trying to be) Most shops are open for bargaining. Oh may be you should stay away from the government house area. there's a large protest site there. If you disregard the fact...

The deoxit and deoxit gold really do wonder. At first when I got the M8161 , I didn't understand why everyone here like the M8161 so much. They were very dull sounding and lack detail. Later I noticed that the tube pins were very dirty. After cleaning with caig deoxit and applying some deoxit...

I just upgraded from the HD595 to the HD650 a month ago. The HD650 have a lot better detail and wider soundstage. The high is not as piercing as the HD595 but still very clear and better detail. About the bass , the HD650 have better bass than the HD595 in every aspect. More quantity , deeper ...
