Detailed Comparison

Sound Quality

JBL Tour One M2

JBL Pro Sound delivers punchy, detailed audio.

Engaging, detailed sound with punchy bass — great for pop and rock
Spatial sound feature adds width to the soundstage

Sennheiser HDB 630

The HDB 630's headline strength. Reviewers describe a warm-neutral, natural HD 600-series tuning with a standout midrange, an open and spacious soundstage for a closed-back, and enough neutrality to make it the most EQ-friendly wireless headphone on the market. The consensus is that it is the best-sounding wireless headphone at $500.

Crinacle calls it the best-sounding premium wireless headphone available today — nothing is over- or under-emphasised, everything just sounds natural and 'normal'.
The Headphone Show says that even without touching the app or EQ, the HDB 630 is the best-sounding wireless noise-cancelling headphone in its price range.

True hi-res wired and USB-C listening at 24-bit/96kHz, plus an included BTD 700 dongle that delivers aptX Adaptive to any device — solving the iPhone/Windows codec gap in hardware

An exceptionally deep companion app with a 5-band professional parametric EQ (adjustable frequency, Q and shelves) that reviewers call the best EQ in any wireless headphone

Sound stays consistent as the battery drains and the headphone runs equally well wired, wireless or via the dongle — genuine flexibility for audiophiles

Good all-day comfort with plush, beefed-up padding and a folding, travel-friendly design

Deal Breakers

Active noise cancellation is the weakest of the premium flagships — clearly outclassed by Sony, Bose and Apple, especially on mid-frequency chatter and low rumble
The build is largely plastic and feels under-built for a $500 headphone, with reviewers wishing for metal in the headband or cups
Ear pads are not the most spacious — larger ears touch the inside, and the clamp can require a break after about two hours for some wearers
Microphone and call quality are mediocre, with the mic optimized only to ~10kHz so even the BTD 700 dongle's wideband codec brings little improvement
Touch controls are the slowest-responding of the premium pack, and some early units had touchpad/wear-detection bugs in multipoint mode

GadgetryTech calls it the best-sounding active Bluetooth headphone they've ever heard out of the box — tuned better than most or all closed-back Bluetooth headphones.

The tuning carries classic HD 600-series traits — a warm-neutral balance and a great midrange — though one reviewer flags a slightly slow bass.

The midrange is the standout of the tuning, and Picky Audio named the HDB 630 best-sounding headphone of 2025 for its rare balanced tuning.

There is a slight forward character in the 1-2kHz midrange and a low-treble forwardness around 3-4kHz; the bass stands out in good ways without being a bass-boost machine.

Joshua Valour says soundstage width, placement and fidelity keep up with the best closed-backs, though they still can't match the best open-backs for soundstage.

A Reddit owner describes it as the most crystal-clear, almost open-back-sounding closed-back headphone they have ever heard, and was surprised by the soundstage.

Soundnews estimates soundstage and depth improved by roughly 20-25% over the Momentum 4.

Dissent: an older review of a different Sennheiser model warns the brand's bass-heavy tunings aren't ideal for classical or vocal music — but HDB 630 reviewers consistently describe a far more neutral, balanced signature.

Noise Cancellation

JBL Tour One M2

Surprisingly strong ANC for the price.

True Adaptive ANC is very effective — close to Sony XM5 performance

Sennheiser HDB 630

The HDB 630's clearest weakness relative to its $500 rivals. Reviewers agree passive isolation is good, but active cancellation is the weakest of the premium flagships — outclassed by Sony, Bose and Apple, particularly in the mid frequencies where voices and chatter sit.

SoundGuys says the real improvement over previous Sennheisers is the passive isolation, not the ANC, and that achievable noise attenuation varies significantly with fit.
In SoundGuys' lab test the HDB 630 reduced outside noise by an average of 83%, versus 87% for the Sony WH-1000XM6.
RTINGS notes the very lowest rumbles of a bus or plane engine can still creep in and mid-frequency attenuation is weaker than competitors, though most everyday noise is heavily reduced.
Crinacle calls the ANC the biggest weakness of the 630 — absolutely outclassed by the 'big three' for maximum isolation.
The Headphone Show steers buyers whose top priority is cancelling noise toward the Sony WH-1000XM6 instead.
RecordingNOW says the noise cancelling and build quality are the two areas keeping the HDB 630 from a perfect score.
Running ANC at 100% applies very high acoustic pressure on the ears — one reviewer dialled it down to 75% for comfort.
Switching on transparency (passthrough) mode noticeably degrades sound quality — bass loses power and volume drops, because the processor favours the wired/clean path.
Owner take: one Reddit user finds the ANC fine for everyday use but notes that on flights it can cause headaches and is more annoying to toggle than rivals.
