I ordered the Superlux HD330 and another two headphones (TDJ1000 and Sony MDR7506) so my review will be based on comparing these 3 headphones.
Bass - All of them have good bass but the best for bass would be TDJ1000 and what is best from the HD330? they don't sound like if they are inside a box, they deliver more of a balanced open sound yet still powerful bass.
High Frequencies - Last place TDJ1000 , second place Superlux, first place Sony.
Confort - Superlux! extremely comfortable and my ears completely fit inside the headphones. They are semi open back but noise isolation is good enough to enjoy music.
Cons - The Superlux HD330 fault is the cable, yes it is supposed to be long and coiled, but it is extremely tight and not comfortable to expand.
I tested these headphones on a MacBook Pro, on a Roland FA08 and a Roland Octapad.
MacBook Pro, listening music, honestly amazing, and for such price it is simply wow! in this case the cable length is not a problem at all.
Roland FA08 and Roland Octapad, so when using these headphones on these instruments (a piano and a percussion pad) the cable length is very important for the confort.
On the FA08 the headphones cable passes in front of my chest and disturbs my hands. On the Octapad disturbs me to play the snare drum. Besides the cable being too tight in both cases. If not because of this short cable, then these headphones would be unstoppable.
Quality - feels great, metal construction, sound can easily compete vs 4 times more expensive headphones.
The Jack adaptor is screw type, this is great, so the jack adaptor does not get stuck in your instrument.
Thank you Thomann for great prices, variety, customer service, fast dispatching, safe packing and fast delivery.
I placed this order in times of Covid quarantine, anyway, Thomann works as efficient as usual.
