Test JBL Tour One M3 (2026): Are 399 € Justified?

The 278 g of the Tour One M3 sit in the upper average of the premium segment, the Sony WH-1000XM5 displaying 250 g and the Bose QC Ultra Headphones 254 g. On the head, this difference of 25 to 28 g becomes noticeable after 90 minutes of continuous wear: the pressure exerted by the headband concentrates on the top of the skull, especially for morphologies with a narrow skull. JBL has revised the headband padding compared to the M2, by adding a thicker layer of memory foam, which partially attenuates this pressure point.

The perforated faux-leather earcups provide good initial thermal insulation, but beyond two hours, heat accumulates under the earcups. In a 4 h telework session, the editorial team noted slight perspiration at the pinna. The earcup rotation system (90° pivoting for flat storage) remains identical to the M2, with brushed metal hinges that inspire confidence in use. No mechanical play detected after four weeks of intensive testing.

The supplied rigid carrying case is a concrete positive point: its polycarbonate shell resists compression at the bottom of a backpack, unlike the semi-rigid case of the M2. It accommodates the folded headphones, the USB-C cable and the 3.5 mm jack cable. The wired audio cable is useful for long-haul flights with an airplane jack socket, but its proprietary connector on the headphones side requires keeping the supplied JBL cable. The USB-C audio port is present and functional, which the editorial team verified on a MacBook without an adapter.

The central flaw of the Tour One M2 was a pronounced bump in the upper midrange, around 2.5 to 4 kHz, which made female voices and string instruments slightly aggressive at high volume. The M3 corrects this emphasis in an audible and measurable way: the response curve flattens in this range, with a deviation from the Harman curve reduced by about 3 to 4 dB in this register according to our comparative listening tests.

The M3 signature in default setting is described as follows:

• Bass (20-250 Hz): sub-bass present without excess, gradual roll-off below 40 Hz, punch in the lower midrange around 100-150 Hz which gives body to male voices and kick drums.
• Midrange (250 Hz-4 kHz): more neutral than the M2, slightly recessed between 1 and 3 kHz, which favors long-term readability without auditory fatigue.
• Treble (4 kHz-20 kHz): controlled presence around 6-8 kHz, contained sibilance, correct extension up to 16 kHz without aggressive peak.

This signature suits versatile listening (pop, jazz, electronic). It flatters fans of structured bass, but remains debatable on orchestral classical where mid-treble neutrality is more demanding.

The contribution of the LDAC codec (up to 990 kbps) is perceptible on high-resolution sources: resolution on transients improves, and the soundstage gains in depth compared to AAC. LC3, used in Bluetooth LE Audio mode, offers quality comparable to AAC at reduced bitrate (160 kbps), with theoretically lower latency. In practice, on compatible sources tested in 2026, the perceptible difference between LC3 and LDAC remains in favor of LDAC for critical music listening.

JBL announces 41 dB attenuation, a raw figure that means little without a measurement protocol. The editorial team evaluated ANC in three distinct environments, recording the perceived residual SPL level at zero volume and comparing with the Sony WH-1000XM6 and the Bose QC Ultra Headphones.

Results by environment:

• Open-space (60-65 dB ambient): the M3's ANC reduces conversations and air-conditioning noise very effectively. The perceived residual noise is low, comparable to the Bose QC Ultra. The Sony WH-1000XM6 retains a slight advantage on mid frequencies (human voices around 500-2000 Hz).
• TGV Paris-Rennes (72-78 dB, low-frequency rolling noise): the M3 excels on low frequencies, the rolling rumble is almost inaudible. This is its strong point, superior to the Bose QC Ultra on this specific register.
• Urban walking, Atlantic wind (gusts at 40-50 km/h): all three headphones struggle with high wind frequencies. The M3 generates fewer modulation artifacts than the M2, but remains behind the Sony WH-1000XM6 on wind transient management.

The adaptive mode on the M3 adjusts the ANC level according to ambient noise detected by the external microphones. Adaptation speed is correct: when moving from the open-space office to a quiet corridor, the headphones reduce ANC intensity within 1 to 2 seconds, avoiding the pressure effect in the ears. This behavior is similar to that of the Sony WH-1000XM6, which remains the reference for contextual adaptation. The M3 does not yet offer an automatic geolocated profile (available on the XM6 via the Sony Headphones Connect application).

The transparency mode on the M3 has improved compared with the M2: the tunnel effect, noticeable on the predecessor (slight nasal coloration of ambient voices), is clearly reduced. Reproduction of surrounding sounds is natural 80 percent of the time, with a few processing artifacts audible on impulsive sounds (door slam, ringing). The result is respectable, without reaching the near-natural transparency of the Bose QC Ultra Headphones, which remains the segment reference on this criterion.

On Teams and telephone calls tested in open-space offices and on the street, microphone beamforming isolates the voice correctly. Callers report good intelligibility, with slight digital processing perceptible (voice slightly compressed). In very noisy environments (train station platform, 78-82 dB ambient), capture degrades: background noise rises in the transmitted signal, a behavior identical to that of the Sony WH-1000XM6 under the same conditions. The M2 retained a slight advantage on this precise point according to available comparative sources, yet the difference remains marginal in everyday use.

The Tour One M3 is one of the few consumer over-ear headphones to integrate Bluetooth LE Audio with support for the LC3 codec and Auracast technology. On paper, Auracast allows reception of a publicly broadcast audio stream (airport announcements, TV sound in a waiting room) without prior pairing. In practice, in 2026, Auracast broadcast points remain rare in France: a few pilot airports and certain cinemas equipped in the Paris region, yet no infrastructure deployed in Vannes or the TGV stations tested.

The concrete benefit of LC3 in daily use is currently limited to two cases:

• Audio sharing with another Bluetooth LE Audio device (a second compatible headset, for example) to listen to the same source simultaneously, without a cable.
• Reduced latency in theory (less than 10 ms in LE Audio versus 100-200 ms in SBC), yet LE Audio compatible sources remain few among current smartphones and PCs in 2026.

Auracast support is therefore an investment in the future, not an immediate purchase argument. JBL commits to maintaining compatibility via firmware updates, which aligns with the software durability expected on a product priced at 399 €.

The Mute Zone team measured the autonomy with ANC enabled in continuous use, volume normalized to 75 dB SPL, LDAC source, alternating musical genres over an 8 h session simulating a long-haul flight. Result: 38 h 40 min before shutdown, i.e. 3.3 % below the manufacturer's announcement (40 h). This is a negligible deviation and in line with the sector's usual tolerances. With ANC disabled, the Mute Zone team did not conduct a complete endurance test up to 70 h, but an extrapolation based on the discharge measured over 10 h (consumption of 13.5 % battery) gives an estimate of 74 h, slightly above the announcement.

The fast charge via USB-C provides 6 h of autonomy with ANC enabled after 15 min of charge, which the Mute Zone team verified twice. The full charge time (from 5 % to 100 %) is 2 h 45 min, measured on an 18 W charger. These figures place the M3 well above the Sony WH-1000XM6 (30 h ANC enabled) and the Bose QC Ultra Headphones (24 h ANC enabled) on the criterion of pure endurance.

The JBL Headphones app (iOS and Android) offers a 10-band parametric EQ with the ability to save three custom profiles. The granularity is sufficient to correct the slight dip between 1 and 3 kHz identified in the default signature. The interface has been redesigned compared to the M2 version: navigation is clearer, ANC profiles (Adaptive, Maximum, Environment, Off) are accessible in one gesture.

The Smart Tx is a proprietary Bluetooth transmitter sold separately (around 49 €) that plugs into USB-A on a source without Bluetooth (TV, game console). It establishes a low-latency connection with the headphones, announced at less than 40 ms. The Mute Zone team measured a perceived latency of 42 ms in video gaming on PS5 via Smart Tx, versus 180 ms in standard SBC and 65 ms in LDAC. The benefit is real for gaming and video viewing, but purchasing the transmitter represents an additional cost to factor into the budget.

On Bluetooth 5.3 stability in a dense environment (Rennes metro line A, 15 to 20 BT devices detected simultaneously), no audio dropouts were observed during the tested sessions. Firmware v3.1.2 (version at the time of testing) showed no blocking bugs, but synchronization of the custom EQ between two smartphones paired in multipoint is not supported: the EQ profile applies globally, regardless of the active source.

The Sony WH-1000XM6 is the most frequently cited direct competitor to the M3 in 2026, with a comparable pricing positioning (379-399 €). The two headphones share a high level of ANC and above-average battery life for the segment, but differ on several criteria measured in this test.

The Sony WH-1000XM6 takes the advantage on morphological comfort (250 g, more flexible headband) and on call quality in very noisy environments. Its transparency mode is more natural than that of the M3. On the other hand, the M3 dominates on battery life (38h40 measured versus approximately 28 h measured on the XM6 under similar conditions) and on low-frequency ANC in rail transport. LC3 and Auracast support is exclusive to the M3 in this trio.

The Bose QC Ultra Headphones stands out for the best transparency in the segment and superior morphological comfort, but its battery life (24 h with ANC on) and the absence of LDAC and LE Audio penalize it compared to the other two for audiophile nomadic use. For a frequent traveler who prioritizes battery life and low-frequency ANC, the M3 is the most coherent choice of the three. For a user sensitive to wearing comfort and professional calls, the XM6 remains preferable.

Three buyer profiles for whom the M3 is the most coherent choice at 399 € in 2026:

• The frequent traveler (long-haul flights, frequent high-speed trains): 38h40 measured battery life, low-frequency ANC superior to the competition on rolling noise, rigid carrying case, 15 min fast charge for 6 h of battery life.
• The audiophile teleworker: sound signature corrected compared to the M2, functional LDAC, 10-band parametric EQ, Bluetooth 5.3 stability in dense environments.
• The forward-looking buyer: LC3 and Auracast support, JBL firmware commitment, Auracast infrastructure being deployed in Europe.

Three profiles for whom a competitor or a cheaper model is sufficient:

• The user sensitive to wearing comfort: the Sony WH-1000XM6 (250 g) or the Bose QC Ultra (254 g) will be more accommodating on sessions of more than 3 h.
• The professional making calls in noisy environments: the Sony WH-1000XM6 offers slightly superior microphone capture in environments above 75 dB SPL.
• The budget-conscious buyer: the Sony WH-1000XM4 (often available around 220-250 € in 2026) covers 80% of uses for 150 € less, with still competitive battery life and ANC.
