Focal Bathys vs Fostex TH610

Last updated: October 11, 2026

Short answer: the Focal Bathys. It ranks #103 of 216 over-ear headphones by sound quality, rated 3.7/5, at $799; the Fostex TH610 ranks #119, rated 3.6/5, and costs $799.99, which makes this an easy call rather than a real tradeoff.

Focal Bathys vs Fostex TH610

Why pick the Focal Bathys: Bluetooth 5.1 with SBC, AAC, aptX and aptX Adaptive, active noise cancelling and a rated 30 hours of battery make it a full wireless travel headphone, and a wired connection is still available. Watch for: A 6.3 dB dip near 9.4 kHz and mild treble reduction soften cymbals and sibilance.

Why pick the Fostex TH610: Crinacle’s measurement gives it a preference score of 72 with a slightly warm overall tilt, a solid result for a closed-back headphone. The tradeoff: At 0.8 lbs (375 g) it is on the heavier side for a closed-back headphone.

Buy the Focal Bathys. It is rated higher for sound quality than the Fostex TH610 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

Focal Bathys ranking card

Pros: Bluetooth 5.1 with SBC, AAC, aptX and aptX Adaptive, active noise cancelling and a rated 30 hours of battery make it a full wireless travel headphone, and a wired connection is still available. Bass is slightly boosted, about 1 dB at sub-bass and 2 dB from 60 to 200 Hz, for a warm, punchy low end. The 2.0 dB deviation is smooth, and a 76 preference score is respectable for a wireless model.

Cons: A 6.3 dB dip near 9.4 kHz and mild treble reduction soften cymbals and sibilance. The tilt is on the warm side, so brightness and detail are subdued. The HIFIMAN Audivina holds a higher rating for a lower price, though the Bathys is the one with ANC and a battery.

Fostex TH610 ranking card

Pros: Crinacle’s measurement gives it a preference score of 72 with a slightly warm overall tilt, a solid result for a closed-back headphone. Its 25 ohm impedance and 98 dB/mW sensitivity let a phone or laptop drive the 50 mm dynamic driver without a dedicated amp, and the closed back keeps sound from leaking in shared spaces.

Cons: At 375 g it is on the heavier side for a closed-back headphone. The Denon AH-D5200 rates higher and costs less, and the Focal Bathys rates higher at the same price while adding wireless convenience.
