P2
Product 2: JBL Grip Bluetooth Speaker

Reviewers describe the physical build as durable, using tough grille materials or a front-firing driver with passive radiators rather than any advanced bracing discussion.
Charging time
P1
Product 1: Bose SoundLink Flex Portable Speaker,...
2.3
Charging is a recurring weakness: reviewers repeatedly cite about four hours to recharge, which some call slow or disappointing.
P2

P2
Product 2: JBL Grip Bluetooth Speaker
4.3
Most reviewers like the can-like upright design, compact shape, colors, and light strip, though one reviewer is less convinced by the upright-only form.
Detail retrieval
P1
Product 1: Bose SoundLink Flex Portable Speaker,...
4.3
Detail retrieval is a strength for the size, with reviewers hearing crisp detail, nuance and separated musical layers.
P2
Product 2: JBL Grip Bluetooth Speaker

Distortion at high volume
P1
Product 1: Bose SoundLink Flex Portable Speaker,...
3.5
High-volume behavior is mixed: some reviewers say Bose processing keeps distortion controlled, while others heard clarity drop or distortion at higher volumes.
P2

Dynamic headroom is supported by TechRadar's bass comments, though the broader evidence suggests dynamics are good for size rather than huge.
P2
Product 2: JBL Grip Bluetooth Speaker
4.0
Reviewers find the 16W output surprisingly potent for the size, enough for personal spaces, picnic tables, or small gatherings rather than full parties.
Energy efficiency
P1
Product 1: Bose SoundLink Flex Portable Speaker,...
4.0
Energy efficiency is only lightly supported, with one reviewer noting effective sleep behavior that avoids unnecessary battery drain.
P2
Product 2: JBL Grip Bluetooth Speaker
3.9
Playtime Boost is framed as an efficiency mode that can extend runtime, but it trades off some low-end sound quality.
EQ customization
P1
Product 1: Bose SoundLink Flex Portable Speaker,...
3.8
EQ customization is one of the clearest upgrades, but reviewers generally describe it as useful while limited to basic bands or presets.
P2

P2
Product 2: JBL Grip Bluetooth Speaker
3.9
The Grip usually sounds good or balanced for its size, but reviewers flag limited deep bass, some high-frequency emphasis, or reduced bass in Playtime Boost.
Handle or strap quality
P1
Product 1: Bose SoundLink Flex Portable Speaker,...
3.8
The fabric loop or strap is useful for bags and hooks, though one reviewer wanted a more flexible loop or included carabiner.
P2
Product 2: JBL Grip Bluetooth Speaker

Reviewers say the Flex 2 gets loud enough for rooms, yards and small outdoor groups, but several note it is not the loudest or best for large spaces.
P2
Product 2: JBL Grip Bluetooth Speaker

Product 1: Bose SoundLink Flex Portable Speaker,...
4.0
Low-volume performance is only lightly supported, but TechRadar specifically heard clearer vocals at lower volume levels.
P2
Product 2: JBL Grip Bluetooth Speaker
4.1

Microphone

Product 1: Bose SoundLink Flex Portable Speaker,...
3.5
The built-in microphone is confirmed for calls and assistant access, though call quality evidence is limited.

4.5
Multipoint is a documented strength in reviews that say the Grip supports two devices at once.
Omnidirectional sound
P1
Product 1: Bose SoundLink Flex Portable Speaker,...
2.0
Omnidirectional sound is a weakness; Tom's Guide specifically describes strong directionality and a narrow soundstage.
P2

4.5
Setup is described as easy, especially Bluetooth pairing and basic controls.
Smart assistant integration (Alexa
P1
Product 1: Bose SoundLink Flex Portable Speaker,...
3.2
The shortcut button can access a phone voice assistant, but reviewers frame this as basic phone-assistant access rather than a full built-in assistant.
P2
Product 2: JBL Grip Bluetooth Speaker
1.0
Smart assistant integration is effectively absent because the speaker lacks the microphone needed to summon an assistant.
Smart features
P1
Product 1: Bose SoundLink Flex Portable Speaker,...

Stereo imaging accuracy
P1
Product 1: Bose SoundLink Flex Portable Speaker,...
3.7
Stereo and imaging evidence is mixed: two-unit stereo mode can add separation, but the single speaker is directional and not especially wide.
P2
Product 2: JBL Grip Bluetooth Speaker
3.1
The Grip is mono by itself, but true stereo is possible only with a second matching Grip; reviewers consider this useful but conditional.
Surround sound simulation
P1Product 1: Bose SoundLink Flex Portable Speaker,...
No score yet
P2
Product 2: JBL Grip Bluetooth Speaker
3.6
Surround-style use is only possible through multiple linked speakers, and reviewers frame it as a multi-speaker effect rather than native surround.
