TELEFUNKEN DELTA PRO – Portable Bluetooth speaker with 35 W, IP67 & hands-free function

The Delta that makes the difference – honest 35W sound, flexible connections and rugged freedom for work, travel and the outdoors.

• Clear 35W sound in a compact format. Two woofers plus tweeters deliver powerful, balanced sound with clear voices – ideal for hi-fi enjoyment, presentations and background music in hotels or offices.
• All-rounder for work, travel & outdoor activities. The high-quality MEMS microphone makes the DELTA PRO a mobile conference solution: calls, online meetings and voice chats remain natural and easy to understand – whether in a home office, apartment or holiday home.
• Your sound, your profile. With the upcoming TELEFUNKEN Audio App (iOS & Android), you can adjust bass, mids and treble to suit the music style, room and application – from lounge to rock to speech focus for podcasts & business.
• Maximum flexibility: Bluetooth, TF card & AUX. Play music directly from TF/microSD (MP3, WAV, FLAC, APE) or connect TV, laptop & older players via 3.5 mm jack – perfect for hotels, exhibitions, holiday homes or campsites, even without a smartphone.
• Robust IP67 companion with long-life battery. Dust and waterproof (IP67) and up to 13 hours of runtime at moderate volume – the DELTA PRO accompanies you comfortably from the desk to the park to the evening session at the lake.
  

The TELEFUNKEN DELTA PRO is the portable speaker for those who seek honest sound instead of marketing-driven bass. Packed into a width of just 22 cm are 35 W of output power with two woofers and a separate tweeter – for clear, powerful sound with present vocals and clean treble.

In everyday use, the DELTA PRO quickly becomes an all-round tool:

• In the home office or hotel, it functions as a clear hands-free device for calls and video conferences thanks to its integrated MEMS microphone.
• On the go, it accompanies you as a robust outdoor speaker with IP67 protection – whether by the pool, on the balcony, while camping or on the terrace.
• Shape your sound with the TELEFUNKEN Audio App (iOS & Android) (coming soon) : boost bass, emphasize voices or neutral hi-fi tuning – the flexible EQ ensures that music, podcasts or presentations sound exactly the way you need them to.
• When it comes to connectivity, the DELTA PRO is consistently practice-oriented:
  • Bluetooth 5.3 for a stable, energy-efficient connection with smartphone, tablet or laptop.
  • TF/microSD slot for independent music playback, ideal for exhibitions, trade fair stands or bars where playlists should simply run through.
  • 3.5 mm AUX-In to directly connect TVs, older audio players or business devices without Bluetooth.
  • TWS function to wirelessly pair two DELTA PRO speakers and create true stereo width – perfect for living rooms, holiday apartments or meeting rooms.
• Thanks to up to 13 hours of battery life (at moderate volume), the speaker reliably plays through a workday, workshop or a long day outdoors.

The compact, robust black casing is easy to store and fits both on the desk and in a travel bag.
