What is included in the price
Every booth ships as a complete, ventilated unit: shell with door, dimmable LED lighting, power at the desk (230 V and USB-C on Solo Flex) and, on Solo Flex, the manual sit-stand desk. Ventilation uses silent EC fans; Solo Flex moves 4.6 m³/min and its PIR sensor switches the fans on when someone is inside.
Installation by Re-Sound or self-assembly
Our installers place a call booth in about 60 minutes, a meeting pod in about 2 hours and a Modular XL in 2 to 6 hours. Solo Flex can also be assembled by two people in under three hours: the booth is a flat-pack construction, so it can be demounted and rebuilt on another floor later.
Test a booth in our showroom
You can sit inside every model in our Beveren-Waas showroom (Mon–Fri 08:00–16:30, by appointment) and hear the difference for yourself before you order.
What the ISO 23351-1 classes mean
ISO 23351-1 measures how much a closed booth lowers the level of speech coming out of it. Solo Flex reduces speech by about 24 dB(A) and Modular XL by 25.9 dB(A): both are Class C. That keeps normal calls and video meetings from disturbing the floor; classes B, A and A+ reduce speech further.
| Class | Speech-level reduction | Re-Sound models |
|---|---|---|
| A+ | at least 33 dB | — |
| A | at least 30 dB | — |
| B | at least 27 dB | — |
| C | at least 24 dB | Solo Flex (24 dB(A)) · Modular XL (25.9 dB(A)) |
| D | at least 21 dB | — |
Thresholds: the minimum speech-level reduction per class. Duo has not been measured yet.
End of life
A booth can be resold or taken apart for recycling: each material is recyclable.
Frequently asked questions about booth prices
How much sound does an office phone booth block?
Solo Flex reduces speech level by approximately 24 dB(A) according to ISO 23351-1, which places it in Class C: a conversation outside the booth sounds like distant murmuring inside. Modular XL achieves 25.9 dB(A), also Class C.
How much does an office phone booth cost?
The Solo Flex office phone booth starts from € 2 740 excl. VAT without installation, or € 3 605 excl. VAT including installation. The Duo meeting pod starts from € 7 615 excl. VAT. Modular XL starts from € 15 000 excl. VAT without installation, or € 17 990 excl. VAT including installation, plus € 7 264 including installation per extra 90 cm element. The largest Modular XL built so far seats 20 people. Prices exclude transport outside Belgium.
What does ISO 23351-1 Class A, B or C mean?
ISO 23351-1 measures how much a booth reduces the level of speech between inside and outside, and groups the result into classes: A+ from 33 dB, A from 30 dB, B from 27 dB, C from 24 dB and D from 21 dB. Solo Flex (approximately 24 dB(A)) and Modular XL (25.9 dB(A)) are both Class C. In practice, Class C turns a normal conversation into distant murmuring: clearly quieter, but not inaudible.
Can we try a booth before we order?
Yes. You are welcome to test every model in our showroom in Beveren-Waas (Belgium) before you order; visits are by appointment, Monday to Friday 08:00–16:30.
How long does installation take, and who does it?
Re-Sound's own installers place your booth: a call booth takes around 60 minutes, a meeting pod around two hours and a Modular XL between two and six hours. Alternatively, the Solo Flex can be self-assembled: two people need less than three hours.
Is the booth wheelchair accessible?
Not as standard: none of our booths is wheelchair accessible in its standard configuration. On request, we can modify a booth to make it wheelchair accessible. Contact us to discuss your requirements.
What is the warranty on a booth?
Every booth comes with a 5-year warranty on the structural frame and body, and a 2-year warranty on electronic components and other wear parts.
