Performance Notes / User Feedback

• The “super bass” claim: the 40 mm drivers are reasonably large for budget headphones, so you should get decent bass, though they are not high-end audiophile drivers.

• There is no active noise cancellation (ANC), despite some “noise cancelling” in the name; spec sheets say “Active Noise-Cancellation: No.” Easy PC Solutions shop

• According to a Reddit user:

  “Has an EQ button. No ANC but pretty useable.” Reddit

• Another Reddit user noted the tuning is a bit “bright”:

  “…the highs are a little bit exaggerated … I find it hard listening to some EDM …” Reddit

• Lightweight and comfortable materials (memory foam, padded headband) charms-online-store.com

• Very affordable (based on current listings) — budget-friendly option for basic wireless listening.

Cons

• No true active noise cancellation (so background noise may be noticeable). Easy PC Solutions shop

• Build quality is decent but not premium (plastic + basic materials).

• Sound tuning might favor treble/highs more, according to some users. Reddit

• The “waterproof” feature is vague — no clear IP rating.

• Button controls may take some getting used to; not touch-sensitive.

• Not a pro-grade mic — likely fine for casual calls but not studio-quality voice.
