## Description

desertcart.co.jp: DOSS SoundBox XL Ultra Bluetooth Speaker, Wireless, 80W, Loud Volume, 18 Hours Playback, Enhanced Bass, Portable, Bluetooth Stereo, Pairing with DSP Technology, Support TF Card/AUX/USB Memory : Electronics

Review: 80wとのことだが、近所迷惑になる音量 最大音量で音楽を聴いていると犬が吠える スタイリッシュで音もクリアーに聞こえる 低音がもう少し響けばよかったかなー
Review: サイズは大きいですが、デザインがシンプルでおしゃれです。最初いきなり大きな音でビックリしましたが、それでも音が割れることはなかったです。説明では再生域が37Hz〜と書いてあったのですが、近くで聴くと結構低音は出ていると感じますが、離れて聴くと全体的に低音はそれ程強調されている感じではないです。ボリュームを上げた方が、全体のバランスが良い様に感じます。Bluetoothもすぐに繋がるし、操作もシンプルなのですが、操作ボタンの文字が薄いので、薄暗いと何のボタンかわかりにくのがちょっと残念。 結構気に入ってます。

## Features

- (80W Powerful Sound) In addition to the 40W subwoofer, it also comes with a dual 20W inner magnet driver, so you can achieve powerful sound up to 80W. Built-in 2.1ch system, you can enjoy sound filling the whole room. The Extra Bass feature allows you to further emphasize the bass and produce more powerful bass
- 【IMPROVED HIGH SOUND QUALITY】Unlike traditional Bluetooth speakers, the SoundBox XL Ultra High Sound Quality Bluetooth Speaker features DOSS proprietary bass reflex duct designed for efficient air flow to improve balance treble, midrange and bass and minimize sound distortion. Dual DSP technology faithfully reproduces every detail of the sound and delivers a balanced loud sound throughout from deep bass to gently hugging mid-highs. Delivers rich bass and natural clear treble
- TWS Connectivity Supported: By connecting two SoundBox XL Ultra small speakers simultaneously, impactful wireless stereo sound will circulate throughout the room, encompassing a comfortable atmosphere.
