VECLOS" (SSA-40M/SSA-40S), Bluetooth wireless portable speakers employing vacuum technology, have been available from Thermos since March.

The company is known for its thermos bottle brand, and this speaker also uses a "double-layer vacuum structure" enclosure that provides excellent sound insulation. Normally, vibrations of the speaker unit transmitted through the enclosure cause noise, but the new speaker uses the characteristics of a vacuum, which "does not transmit vibrations," to achieve clear sound with little noise. We have obtained a copy of the actual product and would like to review it.

The lineup consists of two types, monaural and stereo, with the stereo type in black used this time. The cylindrical form of the Thermos speaker resembles a small water bottle. The two speakers are easy to carry and can be used not only in everyday settings, but also as portable devices for travel and leisure activities. (Note that they are not waterproof.)

By turning the stand under the main unit upside down, the speakers can be fixed at an angle. The angle is just right to direct the sound toward your ears when you are sitting down, but if you want, you can adjust the angle as you like.

The speakers are connected to each other with cables, so there is no need for any other wiring; a single control button turns the power on and off and also serves as a pairing button for Bluetooth devices.

Vocals come through loud and clear!

When I played rock, jazz, and pop songs from my smartphone, the most noticeable difference was in the vocals.

Listening to the song in the equilateral triangle formed by the head and speakers, the vocals floated up clearly and were enveloped by a three-dimensional voice that seemed to be singing right in front of me. On the other hand, the bottom sound is distant, so if you want to focus more on the instrumental performance, this may not be the best choice for you.

Enjoy a luxurious "solitary space"

Of course, the speakers can be used in a large group listening environment, but the most appealing feature is the comfort of the "vacuum sound" that resonates straight to your ears. The advantage of the non-bass-reflex design is that the speakers are not affected by surrounding objects, making them ideal for use in cramped spaces such as on a desk or in a hotel on a business trip. Since human voices can be heard clearly, it is also recommended for radio and English conversation lessons.

The speaker itself measures W52 x D61 x H94 mm and comes in four colors: black, white, red-, and blue. Continuous playback time is approximately 6 hours for the stereo type. A cloth pouch and USB charging cable are included. The monaural type is priced at 10,000 yen and the stereo type at around 18,000 yen. Although they may not be as cost-effective as other products with similar functions, they may be worth considering if the novelty of the vacuum structure and the ease of carrying make them suitable for a variety of uses.
