Si vous traînez souvent dans l'univers de l'audio nomade, vous savez que Teufel n'est pas là pour faire de la figuration. La marque berlinoise a décidé de remettre au goût du jour un de ses produits classiques avec la Boomster 4, et je ne pouvais pas passer à côté de l'occasion de tester la bête.
Pour ce test, j'ai eu entre les mains la version blanche, qui, je dois l'avouer, est super belle. On s'éloigne du look agressif de certaines enceintes pour quelque chose de très épuré, très "Apple-friendly" dans l'esprit, qui s'intègre parfaitement dans un salon moderne ou sur une terrasse. Dès qu'on la sort du carton, on sent que c'est du sérieux : avec ses 3,75 kg et sa poignée robuste, c'est un beau bébé qui inspire confiance, certifié IPX5 pour résister aux éclaboussures, ce qui est toujours rassurant si l'apéro tourne mal.
Côté son, Teufel a mis les petits plats dans les grands avec un véritable système 2.1 embarqué. On retrouve deux tweeters, deux médiums et un subwoofer central de 11 cm, épaulés par deux radiateurs passifs pour les graves. Le résultat est assez bluffant. La technologie Dynamore, chère à la marque, élargit la scène sonore de manière surprenante pour une enceinte monobloc. Les basses sont percutantes sans être trop baveuses, les voix ressortent avec une clarté impeccable, et même à volume élevé, la distorsion reste aux abonnés absents. C'est puissant, riche et détaillé, capable de sonoriser une grande pièce sans forcer. J'apprécie particulièrement les réglages de basses et d'aigus accessibles directement, permettant de sculpter le son selon qu'on écoute du jazz ou de la techno.
Cependant, il manquait un petit quelque chose à cette enceinte pour qu'elle soit absolument parfaite à mes yeux : la connectivité WiFi et AirPlay 2. Nativement, la Boomster 4 est une enceinte Bluetooth 5.0 (avec aptX HD tout de même) et radio, mais elle n'est pas connectée au réseau. Qu'à cela ne tienne, j'ai décidé de corriger ce "défaut" moi-même. J'ai branché sur l'entrée auxiliaire le Belkin SoundForm Connect AirPlay 2. C'est un petit adaptateur magique qui transforme n'importe quel système audio classique en enceinte AirPlay 2. Le mariage est parfait : je profite de la puissance de la Teufel avec la souplesse de l'écosystème Apple. D'ailleurs, si ce petit accessoire vous intrigue, sachez que j'ai publié le test complet du Belkin SoundForm Connect aujourd'hui même sur Mac4Ever,
je vous invite à aller y jeter un œil pour voir comment ça fonctionne en détail

Au-delà de cette petite bidouille AirPlay, il y a une fonctionnalité native de la Boomster 4 que je trouve absolument géniale et trop souvent négligée aujourd'hui : le tuner radio DAB+ et FM. On a tendance à tout miser sur le streaming, mais franchement, j'adore l'idée d'avoir une vraie radio autonome. C'est l'enceinte que je peux emmener en vacances dans un coin paumé sans WiFi, ou utiliser à la maison en cas de coupure internet (ou pour quand les Russes auront fait sauter toute notre réseau internet national). Je suis un gros consommateur de FIP, France Culture et France Info, et pouvoir capter ces stations avec une qualité numérique cristalline grâce à l'antenne télescopique, sans vider la batterie de mon téléphone, c'est vraiment top. La réception est excellente et le fait de ne pas dépendre d'une application pour changer de station est un retour aux sources très plaisant.
(Avec le petit boîtier AirPlay de chez Belkin)
Pour finir sur l'aspect pratique, l'autonomie est tout simplement monstrueuse. Teufel annonce jusqu'à 23 heures d'écoute à volume moyen, et dans mes tests, on n'en est vraiment pas loin. C'est le genre d'enceinte qu'on recharge une fois et qu'on oublie pendant des jours. On regrettera peut-être juste la disparition de la fonction « batterie d’appoint » qui existait sur le modèle précédent, mais vu la qualité globale de l'engin et la présence d'une télécommande bien pratique pour piloter tout ça à distance, on leur pardonne. Pour environ 270 euros, la Boomster 4 est une réussite totale pour moi, qui concilie puissance, qualité audio et polyvalence, surtout si, comme moi, vous lui ajoutez la petite touche de magie AirPlay. Une valeur sûre, et vraiment, à ce prix, n’hésitez pas une seconde. Elle est disponible sur Amazon. Et pour le boîtier AirPlay 2 de chez Belkin, c'est lui !
[Deal du jour] La JBL Boombox 4 est une enceinte imposante, mais ce n'est pas pour rien. Elle délivre en effet un son sacrément puissant en plus d'une très bonne autonomie, idéal pour ambiancer ses soirées. Elle est en promotion pour les soldes d'hiver.

Gl.iNet is using day 1 of CES 2026 to spotlight the Mudi 7 travel router, with 2 listed variants: GL-E5800NA and GL-E5800EU. While the company is now formally presenting the device at the show and directing attention to its travel-focused positioning, it still has not published pricing or a confirmed retail release date in the materials available today. That leaves the Mudi 7’s market placement and availability timeline unresolved, even as the hardware is being discussed publicly at CES. Alongside the CES reveal, Gl.iNet has shared a full specification sheet that clarifies the Mudi 7’s core platform and feature set. It is based on a Qualcomm quad-core 2.2GHz design with 2GB LPDDR4X and 8GB eMMC, and it combines 5G NR with tri-band Wi-Fi 7-class networking, dual SIM dual standby plus eSIM, and a built-in touchscreen for on-device management. I previously saw an early prototype during a visit to Gl.iNet’s Shenzhen offices in October 2025, and the CES-era specification release fills in the internal details that were not available at the time, making it easier to assess what Gl.iNet intends to ship in the NA and EU variants.
With the full specifications now available, the Mudi 7 is confirmed as a compact, battery-powered travel router measuring 157 x 75 x 22.8mm and weighing 300g. That footprint places it closer to a portable hotspot than a small desktop router, with enough thickness to accommodate a touchscreen, battery, and internal antennas.
Gl.iNet lists a 2.8-inch touchscreen as the primary on-device interface. In practical terms, this design choice supports situations where you need to check status or adjust basic settings without relying on a separate phone or laptop, which can be useful when moving between locations or sharing access with other devices.
Power is handled through a built-in 3.85V, 5380mAh battery rated at 20.72Wh, and charging is specified as USB PD/PPS from 5V to 12V with up to 30W input. Gl.iNet also lists power consumption below 30W, which provides a ceiling for expected draw under load, though real battery life will still depend on cellular conditions, connected devices, and the mix of Wi-Fi and wired usage.
Gl.iNet Mudi 7 Router – Connectivity
Cellular is the main uplink option on the Mudi 7, with support listed for 5G NR in both NSA and SA modes. For fallback coverage, it also supports 4G LTE with Cat 20 download capability, which becomes relevant when 5G coverage is weak, when indoor signal conditions push the modem back to LTE, or when a roaming profile limits access to certain 5G services. Gl.iNet still has not published a band list in the specifications you shared, so region-by-region compatibility will depend on the exact supported bands of the NA and EU variants.
For SIM management, the router is specified with dual SIM dual standby and built-in eSIM support. In day-to-day use, that combination is intended to simplify switching between carriers, maintaining a backup line, or separating plans for different regions without having to physically swap cards as often. What remains unclear is how Gl.iNet handles priority rules, failover behavior, and eSIM provisioning in its interface, including whether switching can be automated based on signal or data limits.
On the local network side, the Mudi 7 supports 802.11a/b/g/n/ac/ax/be across 2.4GHz, 5GHz, and 6GHz. The published maximum Wi-Fi rates are 688Mbps on 2.4GHz, 2882Mbps on 5GHz, and 5764Mbps on 6GHz, which sets expectations for its theoretical peak throughput rather than typical sustained performance. Antenna information is also listed, including 2 internal Wi-Fi antennas covering 2.4GHz, 5GHz, and 6GHz, plus 6 internal cellular antennas for LTE and 5G NR, indicating an emphasis on maintaining link quality in variable travel environments.
For wired and tethered connectivity, the router includes a single WAN/LAN Ethernet port rated at 100/1000/2500Mbps, allowing it to slot into networks that offer faster-than-gigabit service while keeping the option for a basic wired LAN connection. It also lists 1 USB 3.1 port, which can be relevant for tethering or attaching compatible peripherals depending on firmware support, but Gl.iNet has not detailed the exact supported use cases yet. External antennas are supported for cellular via 2 TS-9 ports, while external Wi-Fi antenna support is not specified in the sheet, suggesting any range extension is primarily aimed at improving cellular reception.
Gl.iNet Mudi 7 Router – Internal Hardware
The Mudi 7 is based on a Qualcomm platform, listed with a quad-core CPU clocked at 2.2GHz. Gl.iNet does not specify the exact chipset model in the specification sheet, so it is not yet possible to compare its CPU class directly against other travel routers using named Snapdragon or IPQ-series parts. Even so, the stated clock speed and multi-core layout indicate it is designed to handle routing, Wi-Fi management, and cellular tasks concurrently rather than relying on a lower-power single-core design.
Memory is specified as 2GB of LPDDR4X. That capacity is typically relevant for sustaining multiple client connections, running VPN tunnels, and keeping the management interface responsive while traffic is flowing. In practice, how far 2GB goes will depend on the software stack, the number of enabled services, and whether features like traffic monitoring or advanced firewall rules are running continuously.
For onboard storage, the Mudi 7 includes 8GB of eMMC flash. This is generally used for the operating system image, configuration data, and any built-in packages or logs, though Gl.iNet has not detailed how much of that space is reserved versus user-accessible. The specification also does not clarify whether there is any storage expansion path, or how storage is managed over time for items like VPN profiles, connection history, and accumulated logs.
Gl.iNet Mudi 7 Router – Conclusion
On January 6, 2026, the opening day of CES 2026, Gl.iNet is drawing attention to the Mudi 7as its next travel router, listed in 2 variants: GL-E5800NA and GL-E5800EU. The published specification sheet outlines a Qualcomm quad-core 2.2GHz platform with 2GB LPDDR4X and 8GB eMMC, paired with 5G NR (NSA and SA) and tri-band Wi-Fi across 2.4GHz, 5GHz, and 6GHz. The physical and power details are also clear at this stage. Gl.iNet lists the Mudi 7 at 157 x 75 x 22.8mm and 300g, with a 3.85V 5380mAh battery rated at 20.72Wh and USB PD/PPS input up to 30W. Interfaces include a single WAN/LAN Ethernet port rated up to 2500Mbps, 1 USB 3.1 port, and 2 TS-9 ports for external cellular antennas, while a 2.8-inch touchscreen is positioned as a central part of on-device control.
Even with those specifications confirmed, several practical release details remain open on day 1. Gl.iNet has not published pricing, a retail availability date, or a cellular band list for each regional variant, which will determine how well the NA and EU models align with specific carriers and travel use cases. The company has also not provided a complete, Mudi 7-specific breakdown of firmware features and long-term software support, leaving the final day-to-day picture dependent on what is shown during CES and what ships in the retail firmware.

Security teams are still catching malware. The problem is what they're not catching.
More attacks today don't arrive as files. They don't drop binaries. They don't trigger classic alerts. Instead, they run quietly through tools that already exist inside the environment — scripts, remote access, browsers, and developer workflows.
That shift is creating a blind spot.
