Superlux HD-330

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.
Results =
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.

The HD-330's sound incredible. Deep bass and clear treble without overwhelming the mids but not without some sibilance. I recommend placing 2 sheets of toilet paper in front of the diaphragm, under the foam. This will tame the treble if the sibilance is too much for you. The semi open design confines them to home usage and the sound leaks out quite a bit but it offers a wide soundstage that you will only find in much more expensive headphones. Be careful when choosing these : their high impedance can make them sound terrible on some devices such as laptops or phones.
The build quality is great. The plastic feels solid and the headband is made of metal all the way through so you can bend it as much as you want to adjust the clamp.
Looks wise it shares some design elements with beyerdynamic headsets but this particular model still looks quite unique. It is however compatible with beyerdynamic parts. It sports a very professional look and the blue accents make it look quite nice in real life.
The only downside are the pads which should be replaced with AKG 240 Pleather pads for comfort and sound quality.

For this price range I get the sound I like during my pretentious, high fidelity, music listening hours, such as motörhead.

I like the sound, they seem durable, don't hurt my ears (yea, my ears are weird and sensible, love them tho), and they fit my head quite nicely. But I won't lie these tiny exposed cables look veeeery sensitive.
I wish the cable with the stereo jack was a little longer but you can easily get an extended one.
Even tho the plastic box looks cheap it is useful to carry your 'phones in a bag without worrying something will happen. Also, you can carry other fragile stuff in it.

Yes I do recommend these headphones for music appreciation (in my case röck and metal), they are work fine for gaming.

P.S. Do I have to point the price for these things? You really have to do an overkill job to beat these within that price range.

Pro's-

Sound is warm and airy and lows are perfect not too much or too little... But after breaking in.... the mids seem to have opened up and are a lot louder and the bass isnt as woolly its a lot more punchy the highs are well reproduced and are not piercing/not fun to listen to Unlike the stock 681's and others... these headphones make me wow at the sound... for this price.. they are a steal.

These cans are pretty comfortable some reviews said the stock ear pads are quite stiff but i have found them to be fine and i can wear these headphones for hours with no problem they can adjust a lot and fit on my big head fine... lol The headband can be feel a bit hard/presses down a lot but other then that they are fine for me.

Cons-
Cable claims to be a 3m curly cable but is hard to stretch so i just used an extension... You could rewire them but i dont see the point.....

.Also dont buy if you dont have a pre amp as they will be pretty quite... i have them pre amped with my ASUS dgx soundcard and they sound amazing... best superlux headphones i have heard they are a lot clearer then the superlux 681 evo and sound more balanced then the superlux 685's... (one of my favourite headphones..) in this price range.. Even my brother who swears by his headphones listened to them and asked me to order him a pair... he was wowed by them.

Also id like to thank thomann.de for the quick delivery and great product can't wait to order something again!

Use
I use them to lisen music from various sources: hi fi amp, usb soundcard, laptop. For portable equipment (phone, player) impedance can be very high, thuis means the sound level can be not enough (150 Ohm).

Clarity
made with very good quality materials, suitabe for most of the music genres. More or less flat frequency responce (no enhanced bass).
Suitabele to make some mixes, open consturuction is comfortabe to use few hours.

pros
Godd price/perfomance ratio, neutral sound, good tonal balance.
With this headphone you can spent many hours listening to the music.

Cons: short cable. But this can be solved with extension cable 3-5 meters long.

I had no idea how good these headphones would sound until I got them. These are good for just listening music as well as mixing. The highs and lows are well balanced between the mids which means they sound really clear and high end details don't get lost with the bass.

As for design and quality. They are clearly designed to look like Beyerdynamics DT 770 but are semi-open which I do personally prefer. They are pretty comfortable but my head/ears get a bit tired of them after many hours of use. As I've read the stock pads can be replaced with Beyerdynamics velour pads for more comfort and even better sound. Build quality can't really be better for the price. They are not the prettiest headphones and I would't go out for a walk with them as it would look funny but they are clearly not meant for that anyways.

They come with a 3.5mm stereo jack cable and screw-on 6.3mm adapter which is handy. The cable itself could be a little bit longer and less stiff but you can buy headphone extension cable so that's not really an issue.

Overall, I really do recommend these! For me, unbeatable quality and price balance. You have really hard time finding better sounding headphones in this price range!
