What we like about Boult Audio Fluid X

  • Impressive 60-hour battery life with fast charging support
  • Comfortable over-ear design with soft cushioning and a padded headband
  • Balanced sound quality featuring punchy bass and clear vocals for its price range
  • Fast and stable Bluetooth 5.4 connectivity with quick pairing
  • Sleek and modern aesthetic that many users find premium-looking
  • Foldable design makes it highly portable for travel
  • Good call clarity thanks to the Zen Environmental Noise Cancellation (ENC) mic

What we don't like about Boult Audio Fluid X

  • Mixed feedback on build quality, with reports of flimsy plastic and hinge fragility
  • Ears can feel warm or sweaty after extended listening sessions
  • Noticeable sound leakage at volumes above 70-80%
  • Not ideal for competitive gaming due to typical Bluetooth latency
  • Variable fit; may feel too loose for some users or have high clamping force for larger heads
  • Inconsistent bass performance reported by some users who found it lacking depth
  • Poor customer service experiences regarding returns or physical damage repairs

Verdict

The Boult Audio Fluid X is an over-ear wireless headphone featuring 40mm bass-boosted drivers with BoomX technology, Bluetooth 5.4 connectivity, and a foldable, IPX5 water-resistant design. It offers up to 60 hours of total playtime with fast charging support that provides 3 hours of usage from a 10-minute top-up, alongside a dedicated Combat Gaming Mode with 60ms low latency and a Zen ENC microphone for clear calls. Main pros include its extensive battery life, stable multi-device pairing, and comfortable cushioned earcups for long sessions. However, some users have reported concerns regarding brittle plastic build quality, potential sound leakage at higher volumes, and a lack of true active noise cancellation compared to the Pro model.
