If you want active noise cancellation and a stated 30-hour battery life for studying, choose MOVSSOU Million Sold Classic; if you need up to 40 hours of playback and a padded, adjustable over-ear design, choose JUNJIEUNVO BT1638.
For a quiet desk, commute, or study session around low and mid-frequency noise, the MOVSSOU has the more clearly defined focus feature. The JUNJIEUNVO suits listeners who would rather prioritize longer stated battery life and a silver, over-ear design.
MOVSSOU Million Sold Classic vs JUNJIEUNVO BT1638 at a Glance
• MOVSSOU Million Sold Classic — biggest strength: Active noise cancellation and a stated 30-hour battery life. Trade-off: Its battery-life figure is shorter than the JUNJIEUNVO’s.
• Choose MOVSSOU if you want active noise cancellation for study sessions, commuting, or travel.
• Choose JUNJIEUNVO if longer stated playback and an adjustable over-ear fit matter more to you.
• For open ear earbuds for studying: neither is an open-ear or earbud design; both are over-ear headphones.
The MOVSSOU’s main point of difference is active noise cancellation. Its feature description specifies that the system targets a range of low- and mid-frequency sounds, including aircraft and car-engine noise. That makes it the more purpose-built option if you study near steady background noise or want headphones designed to reduce some of the rumble of a commute. Noise cancellation is not a guarantee of silence, but the active system gives this model a specific advantage over a headset that relies only on ear cushions for isolation.
It is an over-ear Bluetooth model with 45 mm dynamic drivers, a built-in microphone for hands-free calls, and touch controls for noise, voice, calls, and volume. The listed battery life is 30 hours, and the headphones also have a 3.5 mm jack. In everyday terms, that mix should appeal to someone who alternates between listening, calls, and longer stretches away from a charger. The 45 mm driver size tells you about the speaker hardware, not by itself how the headphones will sound to you; the product information describes the sound as full and bass-forward, but personal preference still matters.
The soft, pressure-relieving ear pads and lightweight design are intended to make extended wear more comfortable. That may suit a student settling in for a long reading block, or someone who wants over-ear coverage at a desk. They are not bone-conduction headphones, and they do not leave the ears open. If you specifically want open ear earbuds for studying so you can keep your ears uncovered, this is the wrong style.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
Who should skip it: Skip the MOVSSOU if your main priority is the longer battery figure offered by the JUNJIEUNVO, or if you want an open-ear design rather than over-ear headphones.
The JUNJIEUNVO BT1638 is an over-ear Bluetooth headphone with a stated playback time of up to 40 hours. That longer figure is its clearest practical advantage over the MOVSSOU’s 30-hour battery life. If you listen through extended study days, travel, or several sessions between charging opportunities, the battery specification may make the JUNJIEUNVO the more appealing fit. Its listed charging time is two hours, giving you a stated reference point for a full charge.
Comfort and adjustability are central to its design. It has cushioned ear cups, a padded headband, and an extendable headband with metal components. Those features make it a reasonable choice for someone who wants a fit they can adjust rather than a fixed-size band. It is listed at 12 ounces, while the MOVSSOU is listed at 9.92 ounces, so the JUNJIEUNVO is the heavier of the two by the supplied figures. That is worth considering if you are sensitive to weight during long listening sessions, though weight alone cannot determine comfort for every head or fit.
Its noise control is passive. The cushioned ear cups may help create some physical separation from surrounding sound, but this model does not list active noise cancellation. Bluetooth and AUX connectivity are specified, along with 40 mm dynamic drivers and button and touch controls. Its silver finish and chrome accents give it a more style-forward look than the MOVSSOU’s listed Baby Pink finish. The product information does not give a microphone feature, so I would not choose it on the assumption that it has the MOVSSOU’s stated call-focused microphone setup.
Who should skip it: Skip the JUNJIEUNVO if active noise cancellation is essential for studying around steady background noise.

• Best for passive-only noise control → JUNJIEUNVO BT1638. Its noise control is listed as passive, so it avoids relying on an active cancellation feature.
• Best bone conduction headphones for studying → neither. Both products are over-ear headphones, not bone-conduction models.

Buying Considerations
Next, weigh battery life against the features you will actually use. The JUNJIEUNVO lists up to 40 hours and a two-hour charging time. The MOVSSOU lists 30 hours and adds a 3.5 mm jack, active cancellation, and a built-in microphone. Those figures describe the products’ stated specifications, not a guarantee of identical runtime in every listening situation. Choose based on whether extra playback time or the MOVSSOU’s additional listed functions are more useful to your routine.
Fit and form factor matter just as much as the feature list. Both are over-ear models, so neither is a substitute for open-ear earbuds or bone-conduction headphones. The MOVSSOU has the lower listed weight and describes its ear pads as pressure-relieving. The JUNJIEUNVO emphasizes a padded headband and an adjustable band, but it is heavier by the supplied figures. If you tend to wear headphones for several hours, consider which of those design details addresses your own comfort needs.
Finally, be precise about calls and sound expectations. The MOVSSOU specifically lists a built-in microphone and hands-free calling features. The JUNJIEUNVO’s supplied information does not specify a microphone, so its call performance cannot be compared on the same basis here. Both use dynamic drivers, with 45 mm drivers in the MOVSSOU and 40 mm in the JUNJIEUNVO. Driver size alone does not establish which one will sound better; the more useful choice is the model whose stated features match your listening environment and daily habits.
For studying, I would choose the MOVSSOU Million Sold Classic because active noise cancellation, a built-in microphone, and a 3.5 mm jack make it the more versatile fit for focused listening and everyday calls. Its stated 30-hour battery life is shorter, so I would choose the JUNJIEUNVO instead if longer playback is my main priority. Neither is an open-ear or sleep-specific headphone. My pick is the MOVSSOU for its more clearly defined study-focused feature set.
