NUASI Wireless Bluetooth 5.3 Sports Headphones (IPX7, Deep Bass) – Black
Product description
The essentials
NUASI’s wireless in-ear sports headphones are built around a pretty clear brief: give you Bluetooth freedom for running and gym-style movement, keep the fit stable, and protect the hardware with an IPX7 waterproof rating. On paper, they also lean into bass, with 11 mm dynamic drivers and noise isolation technology aimed at helping the music stay front and centre when you’re outside or in busy spaces.
The Bluetooth connection is another strong angle. With Bluetooth 5.3, the idea is a faster, more stable pairing with your device, plus a claimed range that extends further in open space than in obstacle-filled areas. If you’re shopping for a sports-focused pair rather than general commuting headphones, that combination of fit + durability + wireless stability is the main reason people consider models like this.
What you’ll notice day to day
Comfort matters with in-ears, especially once you’re moving. These headphones use ear hooks designed to help stop them slipping during jogging, cycling, or riding. They also come with 4 pairs of different earplug sizes, so you can dial in the seal—something that can affect perceived bass and overall isolation quite a lot.
Sound is described in a conventional-but-useful way: powerful bass, rounded mids, and clear treble. That “deep bass” direction will likely suit most listeners who want music to hit during workouts, but it’s worth keeping in mind that if you prefer neutral or very detailed audiophile sound, a bass-forward tuning may feel a bit less balanced.
Here’s a practical example: imagine a 30-minute run where wind and traffic noise are constant. A decent in-ear seal plus noise isolation tech should help you hear vocals and beats clearly without turning the volume up too aggressively. Still, no noise isolation is magic—noise will vary depending on how well the earplugs seal your ears.
Connection, range and charging reality
Bluetooth 5.3 is there to support a fast, stable connection, and the product description suggests the connection is less likely to drop “out of the line”. Range is stated as up to 30 metres in open space and up to 10 metres in obstacle space. Those figures are helpful for commuting around the house, taking calls while you move, or leaving your phone in a pocket/bag while training—though real-world performance will always depend on your environment and device.
Battery life is rated at up to 16 hours with a full charge. Charging is described as taking around 1.5 hours under normal circumstances. There’s also a mention of charging status being displayed on your device when in operation, which is a small but genuinely practical convenience.

Where it shines (and where it might not)
These are best treated as sports headphones first and general “all-day” audio second. The ear hooks, multiple earplug sizes, IPX7 waterproofing, and the sports-oriented Bluetooth connection all point to a purchase for people who jog, cycle, or train outdoors and want fewer worries about fit and sweat.
It might not be the most suitable choice if you’re chasing a highly neutral, studio-style sound profile, because the description clearly prioritises deep/powerful bass and rounded mids. Also, if you often use headphones mainly for calls in very noisy environments, you’ll want to be cautious—there’s no specific microphone or call-performance detail provided here.
Buying verdict
It’s a good fit if you want wireless sports headphones with ear hooks for stability, IPX7 waterproof protection, and a bass-forward sound approach, while also valuing a Bluetooth 5.3 connection that’s designed to stay stable during movement. If you’re buying for running or cycling and you’re happy to focus on comfort and workout practicality, it ticks a lot of the boxes.
You may want to skip it if you’re specifically sensitive to bass emphasis, or if your priority is call-focused features that aren’t mentioned in the provided details. As with any in-ear, the final experience will depend heavily on getting the right earplug size and achieving a good seal.
Mini FAQ

The design uses ear hooks, and the kit includes four different earplug sizes, both intended to help reduce slipping during sports like jogging and cycling.
What Bluetooth range can I expect?
The description states up to 30 metres in open space and up to 10 metres in obstacle space, but real-world results can vary with your environment.
How long do they last on a charge?
Battery life is claimed at up to 16 hours, with around 1.5 hours to fully charge under normal circumstances.
Is the sound tuned for bass lovers?
