Excellent audio quality
Very good for the price.
Love them! just incredible sound, detail, perfect for me as a vocal performer
They are magnificent, both in sonority and in build quality.
Very comfortable to wear, even for prolonged sessions.
The cable is very good, well built, does not twist and is not too heavy.
They are certainly IEMs to buy.
Extremely good for the price, I like their signature
Great product.Popped in a SD card with music and started playing. Only gripe was the menu being in Chinese and after some menu browsing managaed to change it.
The Poseidon is a comfortable headphone to wear and is less fatiguing to the ear. It is padded well with a velor ear cushion. That makes it well breathable and prevents sweat. I use this as computer audio accessory.
This headphone leans more towards the upper frequences with less emphasis on bass. However the available bass is snappy instead of being muddled. The headphones tend to be a bit muddled in the lower mid frequency range when new. But as it wears in, the lower mid frequencies get well detailed especially for male vocals. There is more air on top. I have not experienced any fatiguing sibilance though. The music listening is not relaxed but edges towards more citical detail and wider sound stage. Though it is not a class leader in its budget class like the Senheiser HD 600S.
My main grouse with headphone is the creaking of the slider adjust mechanism on the headband. It feels flimsy and not engineered well. The quality of the cans and driver is price appropriate. Also the coating on the head band is wearing off. But then my experience with Chinese headphone in this area is grim. I have used Hifiman and Ibasso headphones. And is dissappointed with quality of the mechanical build. The Harmonicdyne is the better of the lot.
To sum up, I dont think its worth the full price siince I got it for a good discount deal.
I chose to buy this item because it was cheaper than other similar items. 0 regrets on the purchase; I use it to store my IEMs. Great way to stash your IEMs without worries!
Great sound for a BT IEM. Long lasting charges and surprisingly very comfortable. I never knew bt was this good. highly recommended
Buy it only second hand OR low price.
Without the adapter it sounds horrible with my Oxygen. With adapter they are very good but incompatible with UAPP.
