I give 5 stars solely for the sound; comparing it to the Haylou S40: the sound of the S33 is a 5, while the S40 is a 3. 33s play a deep, tight low end without buzzing, excellent mids, the highs are amazing, in general you can hear a lot of details, the soundstage is huge, impressively wider than the head, the effect is simply terrifying, 40s subs are not played well, the high bass is boosted, it buzzes like a galvanized bucket, the mids are toxic and dirty, the highs are okay but get lost in the background of the boosted high mids. The 33s have a stronger grip, fit more comfortably, can even be used for sports, but may cause discomfort after an hour; they absolutely don't squeak or rattle, but the 40s are a terrible squeaky clunker. Disadvantages: worse than Bluetooth, one wall and a turn already cause stuttering; with the 40x, everything works fine through 3 walls; the build quality and materials are a bit simpler, the volume is lower than the 40x, distortion starts at maximum volume, the amplifier clips, but even this volume is too high for me. The hinges turn stiffly, it's unusual; the ear pads are questionable; the equalizer is not working on either one, just differently.
Excellent product 👍 the size fits a large head perfectly, the sound is very clear, the build quality is excellent, and the delivery was fast.
They are good for the price they have.
Thank you very much to the seller for the high-quality product and fast delivery! I recommend it :)
