The TREBLAB HD-Max is a portable Bluetooth speaker with a similar design to the TREBLAB HD77 and the JBL Xtreme 3. It's well-built with an IPX6 rating for water resistance that certifies it for protection against direct contact with water for up to three minutes, so you can take it outdoors with you without needing to worry about it getting a bit wet. It comes with a removable carrying strap that has a built-in bottle opener, so you can enjoy drinks with friends while you're playing your favorite songs. Its long-lasting battery life also makes it great for long listening sessions spent outdoors. It comes with three sound modes: 'Indoor,' Outdoor,' and 'Bass Boost.' With its 'Indoor' preset selected, the stereo speaker has some boom in its bass range, and its somewhat balanced mid-range ensures vocals and lead instruments sound clear and present in the mix. That said, it lacks low-bass, so you can't feel the deep thump and rumble in bass-heavy music like hip-hop, and there isn't a graphic EQ to tweak its sound to your liking.
Our Verdict
The TREBLAB HD-Max is passable for music. With its 'Indoor' preset selected, this stereo speaker has some boom in the bass range, and its mid-range is somewhat balanced, so vocals and lead instruments sound clear and present in the mix. However, it still lacks low-bass, so you can't feel the deep thump and rumble typically present in bass-heavy music like hip-hop or EDM. Unfortunately, aside from its presets, there aren't more robust sound customization features like a graphic EQ to tweak its sound to your liking. It also has middling directivity, resulting in a narrow and directional-sounding soundstage.

The TREBLAB HD-Max is middling for watching videos and movies. While its Bluetooth latency with iOS devices is too high for watching videos without syncing issues, it performs better with Android devices. However, some apps compensate for latency differently, and your experience may vary. With its 'Indoor' mode enabled, it also lacks low-bass, so you can't feel the deep thump and rumble in action-packed scenes. While the HD-Max can get loud, there's some compression present at max volume that degrades the quality of your audio as you increase its volume.

The TREBLAB HD-Max is decent for podcasts. It's pretty portable, so you can easily move your audiobook or podcast from room to room. With its 'Indoor' preset enabled, it has a somewhat balanced mid-range that ensures voices and dialogue reproduce clearly and accurately in the mix. That said, higher-pitched voices sound both dull and harsh at times due to the recessed low-treble range, and there isn't a graphic EQ you can use to tweak its sound to your liking. It also has middling directivity, so you can't hear your audio as clearly from all angles.

The TREBLAB HD-Max doesn't support voice assistants.
The TREBLAB HD-Max is alright for outdoor use. It's rated IPX6 for water resistance, meaning it's certified for protection against direct contact with water for up to three minutes, so you don't have to worry about it getting a bit wet from some light rain when taking it outdoors with you. It can get loud enough to fill a large space with sound, and its long-lasting battery life is great for long listening sessions spent outdoors. Unfortunately, with its 'Indoors' preset enabled, it lacks a thumpy low-bass, and there aren't more comprehensive sound customization features like a graphic EQ to adjust its sound to your liking. The manufacturer says you can use its 'Outdoor' mode to boost its treble and its 'Bass Boost' mode to bump up its bass.

Test Results
The TREBLAB HD-Max is a medium-sized portable speaker with a similar design to the TREBLAB HD77, though it's larger and doesn't come with any RGB light rings. It comes with hooks you can use to clip its strap to make the speaker easier to carry. Also, like the JBL Xtreme 3, its strap comes with a built-in bottle opener, which is handy when you want to enjoy music and drinks with friends.
The TREBLAB HD-Max has excellent portability. Though it's larger than the TREBLAB HD77, this battery-powered speaker is still fairly lightweight and comes with a removable carrying strap to help bring it along with you when on the go. You can hold it in one hand, though it's a bit less comfortable if you have smaller hands.
The TREBLAB HD-Max has great build quality. Like the TREBLAB HD77, the speaker feels solid and sturdy. It has an IPX6 rating for water resistance, certifying it for protection against direct contact with water for up to three minutes. It means you can take it outside with you without needing to worry about it getting a bit wet. There's a sealable flap underneath the speaker to protect its inputs, and like the JBL Xtreme 3, it has hooks built into its sides near its control buttons to clip its removable carrying strap.
The TREBLAB HD-Max has a very good selection of decently easy-to-use, texturized controls. You can use the power button to switch between its wireless and AUX modes and to connect the speaker to another compatible speaker when you want to create a stereo pair. You can also press and hold its volume buttons to skip your tracks or backtrack. You can use its play/pause button to answer and decline phone calls as well as redial the last phone number on your call log. Double-pressing it switches between its three presets: Outdoor, Indoor, and Bass Boost. It's best not to double-press the button too fast since you can unintentionally pause the speaker instead.
Similarly to the TREBLAB HD77, the HD-Max emits audible chimes to inform you when it's on/off, once it's reached max volume, when it gets connected or disconnected from a paired device, and when its battery is low. Its battery indicator lights flash blue when you turn the speaker on and red when you turn it off. You can also quickly press the power button to check the speaker's battery level when it's turned off. When the speaker's 'Indoor' mode is enabled, the light between its power and volume button lights solid blue. For 'Outdoor Mode', it flashes twice, and for 'Bass Boost' mode, it flashes three times. You can see a video of the light flashing for its 'Outdoor' mode here.

The TREBLAB HD-Max's frequency response accuracy is passable. Though the overemphasis in the high-bass range provides its sound profile with some boom, it lacks low-bass, so you can't feel the deep thump and rumble typically present in bass-heavy music like hip-hop or EDM. Its mid-range is somewhat balanced, so vocals and lead instruments reproduce clearly and accurately in the mix. However, higher-pitched vocals and instruments sound alternately dull and harsh due to the recessed low-treble. Unfortunately, aside from its three presets, 'Indoor', 'Outdoor', and 'Bass Boost', there aren't more robust sound customization features like a graphic EQ to adjust its sound to your liking. The manufacturer says you can use its 'Outdoor' mode to boost its treble and its 'Bass Boost' mode to bump up its bass.
Note: The TREBLAB HD-Max was tested horizontally, with its 'Indoor' preset enabled.
The TREBLAB HD-Max's soundstage performance is fair. It can play stereo content without downmixing it to mono, meaning you can distinguish between its left and right channels. You can also connect it to another compatible speaker to create a stereo pair. It has disappointing directivity, resulting in a soundstage that's perceived as narrow and directional. The overemphasis in the treble range also results in an uneven-sounding soundstage.
Note: The test results represent the most recent version of the TREBLAB HD-Max, that supports Bluetooth 5.0. If you own the older version of this speaker that supports Bluetooth 4.2, you can’t connect it with the newer model to create a stereo pair.
The TREBLAB HD-Max has decent dynamics. It can get pretty loud and can easily fill a large room with sound. That said, there's quite a bit of compression present at max volume that degrades the quality of your audio as you bump up the speaker's volume.
The TREBLAB HD-Max's battery performance is great. It lasted over 22 hours from a single charge, which is great for long listening sessions. However, battery performance varies depending on your usage habits and selected volume level. There's a power-saving feature that turns the speaker off following 10 minutes of inactivity.
The TREBLAB HD-Max comes with an AUX port you can use to wire your devices to it. The speaker can also act as a power bank for your devices via its USB output.
The TREBLAB HD-Max has decent Bluetooth connectivity. It has an outstanding range, so your paired device stays connected to the speaker even when you aren't close by. Its latency with iOS devices is too high for watching videos and causes syncing issues between the visuals you see and the audio you hear. It performs better with Android devices, though some apps compensate for latency differently, and your experience may vary.
