If you want long listening sessions with active noise cancellation, choose Monoprice BT-600ANC; if you need an open-ear fit for workouts and awareness, choose HAKII Open Ear. For teens, the key decision is whether blocking distractions or staying connected to the surroundings matters more.
Monoprice BT-600ANC vs HAKII Open Ear at a Glance
• Monoprice BT-600ANC strength: Hybrid active noise cancellation, with noise reduction of up to 35 dB; trade-off: its over-ear design covers the ears rather than leaving them open.
• HAKII Open Ear strength: Clip-on, open-ear design with IPX5 water resistance; trade-off: it has no active noise cancellation.
• Monoprice BT-600ANC strength: Up to 40 hours of playback and a foldable design with a carrying case; trade-off: it is an over-ear headphone rather than a lightweight clip-on earbud.
• HAKII Open Ear strength: Up to 6 hours per charge, with up to 18 hours total using the case; trade-off: its total stated listening time is shorter.
• Choose Monoprice for quieter listening, long sessions, and travel; choose HAKII for workouts, sweat resistance, and hearing more of your surroundings.
The Monoprice BT-600ANC is the more suitable pick when a teen wants to settle into music, videos, or calls without as much surrounding noise. Its hybrid active noise cancellation uses internal and external microphones to reduce low- and mid-frequency sounds, with noise reduction of up to 35 dB. That makes it the more compelling design for listening near traffic, on a bus, or in another noisy setting—though noise cancellation does not mean every sound disappears.
Its custom-tuned 40 mm drivers, Bluetooth 5, and support for aptX HD, AAC, and SBC give it a more feature-rich listening setup than the HAKII. It also has touch controls, an ambient sound mode, multi-pairing, and a stated wireless range of up to 32 feet. The soft earpads, adjustable padded headband, foldable frame, and included carrying case point toward longer listening sessions and carrying it between places.

HAKII Open Ear: Who It's For
HAKII Open Ear is the better match for someone who dislikes having earbuds inserted into the ear canal or wants to listen while remaining aware of nearby activity. Its clip-on shape sits around the ears, and the open-ear design is intended to keep the listener aware of traffic, conversations, and other surroundings. For a teen walking, cycling, or exercising outdoors, that can be a more relevant design choice than active noise cancellation.
The earbuds use 12 mm drivers, Bluetooth 5.4, touch controls, and environmental noise cancellation for calls. That last feature is not the same as active noise cancellation for listening: HAKII does not cancel the surrounding sound for the wearer. It offers up to 6 hours of playback on a charge and up to 18 hours total with the charging case. The IPX5 rating is a specific advantage for sweat and rain exposure, while the stated Bluetooth range is 10 meters.
The trade-off is straightforward: HAKII is less suited to shutting out a noisy room, and its stated total playback time is considerably shorter than Monoprice’s. It also connects to one device at a time, according to the product information. I’d consider it for teens who prioritize outdoor awareness, clip-on comfort, and resistance to sweat or rain. I wouldn’t choose it for someone whose main goal is immersive, quieter listening or switching among multiple connected devices.
• Best for active noise cancellation → Monoprice BT-600ANC. It has hybrid ANC designed to reduce low- and mid-frequency noise, with reduction of up to 35 dB. HAKII has no active noise cancellation.
• Best for staying aware of surroundings → HAKII Open Ear. Its open-ear design is intended to let the listener hear nearby activity instead of sealing the ears under over-ear cups.
• Best for long playback between charges → Monoprice BT-600ANC. It states up to 40 hours, compared with up to 6 hours from HAKII’s earbuds alone and up to 18 hours total with the case.
• Best for workouts and sweat resistance → HAKII Open Ear. Its IPX5 rating and clip-on design make it the more exercise-oriented option in this comparison. The Monoprice data does not specify a water-resistance rating.
• Best for extended, focused listening → Monoprice BT-600ANC. The padded over-ear fit, ANC, ambient sound mode, and long stated battery life are useful when the priority is settling in with audio.
• Best for a teen who wants a microphone-focused option for calls → Monoprice BT-600ANC. Its cVc 8.0 call technology is described as suppressing background noise. HAKII also has environmental noise cancellation for calls, but the available information does not give a comparable call-performance figure.
• Best for Bluetooth codec options → Monoprice BT-600ANC. It supports aptX HD, AAC, and SBC; HAKII’s listed details identify Bluetooth 5.4 but do not specify the same codec options.
• Best for choosing the style before anything else → HAKII for open-ear clip-ons; Monoprice for over-ear headphones. These fit differently, so the preferred feel and listening situation should guide the decision.
For shoppers searching for the best wireless Bluetooth earbuds for teens, the HAKII is the closer match to the earbud-style option, with a clip-on rather than in-ear shape. But that phrase alone doesn’t settle the choice: a teen who mostly listens at home or during travel may get more from the Monoprice’s ANC and longer playback. Someone who mainly wants a sweat resistant headphone for teens to wear during outdoor activity has a clearer reason to consider HAKII.
I would choose the Monoprice BT-600ANC for a teen who wants long playback, over-ear comfort, and active noise cancellation in one set. Its up-to-40-hour playback claim and noise-reduction features give it the stronger case for focused listening and travel.
I’d choose HAKII instead when open-ear awareness and IPX5 water resistance are the priorities.
For teens, my overall pick is Monoprice—unless workouts and keeping the ears open are the main use.
Choose Monoprice for active noise cancellation, over-ear listening, and up to 40 hours of playback. Choose HAKII for an open-ear clip-on design, outdoor awareness, and IPX5 water resistance.
It does not have active noise cancellation for listening. Its environmental noise cancellation is intended to help with calls, while the open-ear design lets surrounding sounds remain audible.
HAKII is the more clearly suited option for workouts: it has an IPX5 rating and a clip-on open-ear design. The Monoprice product information does not specify a water-resistance rating.
Monoprice states up to 40 hours of playback. HAKII states up to 6 hours on a single charge and up to 18 hours total with its case. Monoprice lists cVc 8.0 call technology; HAKII lists environmental noise cancellation for calls.
