The first thing that stands out when listening to the HD800S is the expansive soundstage. It’s absolutely breathtaking. These headphones create an open, almost three-dimensional sound that feels more like you’re in the room with the musicians rather than listening through a pair of headphones...

I have the Topping A90 as an amplifier. If the Topping D90 has the 5 V option as stated above and the Topping D90 was made to work in synergy with the A90, I guess the A90 can take the 5 V from this SMSL, right?

Where on Earth did you see volume button keys on the Cobalt?

Yeah, if you like muffled sound with lots of bass, look at Beats.

An iem that works wonderfully with metal and rock, where those electric guitars can be a bit grating with bright iems. I had never enjoyed L.A. Woman by Doors or The Number of the Beast by Iron Maiden as much as I did with these.

These iems have a sonic signature and a quality to them that reminds me very, very closely of my beloved Sennheiser HD800S. I would dare say that these are a sort of iem version of them. No, they are not a sort of "cheaper version", but the sonically "equivalent version", in the sense that the...

I bought these iems after owning the Fh5 and Fh7 from Fiio. The Fh7 were a worth upgrade over the FH5, which in turn were and still are excellent iems. What sets the Fh9 ahead of its 2 siblings is timbre, separation and high frequencies. You have a feeling instruments are more true to life with...

I suspect when a headphone lowers too much in price, it begins to be critisized more. This does not just happen with headphones, but with any product that has a price. It has to do with psychology and I am not going in to that. I will just say that some headphones I have had costing 600 or 700...

I get bored writing long reviews. I just want to say that these headphones are suitable for all music genres, but they absolutely shine with rock and metal. For these two genres I even prefer them to my Hifiman Arya Stealth and Sennheiser HD800S. The highs are not recessed as someone wrote, but...

Best headphones I've tried up to date (and I've tried the rs1e, the hd650 and the k702 among others)

Excellent headphones. I have the Momentum over ear and these are more balanced and have more extended highs.

Euginius u can't say people must be deaf (which is something close to an insult) and then end up saying: "stop arguing about my taste". I love grado, but the hd650 is more neutral than the 325is (dunno about the hf2)
