Great bit of kit
Not only are these remarkably cheap, but actually do a great job. Connected easily in seconds, really comfy to wear. Sound quality is pretty good. The charge seems to last really well too, I've just done two, 3 hour train journeys and still over 50%. Some earphones I've used are tricky to change track or volume as i have big hands/ fingers, but these are easy with a good size pad to press on. Overall, great value for money.

Amazing quality, low low price
I've tried a few other wireless earbuds in the past, but these far exceed any previous experiences. They are a comfortable bit of kit and quite fashionable-looking. Connectivity was not an issue at all; I simply took the buds out of the clamshell charger (which in itself is seriously well made for the price), tapped the appropriate settings on my phone, and they were connected in a flash. Bluetooth connectivity (in-call/listening to media) is of excellent quality, and the built-in microphone is of equally good quality. Charge seems to last for a really long time (I've used them on and off for 5 days as of time of writing and still not had to really think about charging them up). Continuous use, especially at louder volumes, could cause an issue for your hearing but that is a common theme with all headphones/buds. Visual presentation is top-notch; a classy looking clamshell charger case with a clear panel near the top to view the LED display (only visible whilst charging/connecting earbuds) gives clear concise vision. The buds themselves slot back into their respective charge points wonderfully and feel secure. TLDR; Despite it's small price tag, this is a really wonderful bit of kit that works as well as products twice/three times its value.

Worth the money
Good product, i use one ear when I go to bed, blocks out all the noise and good quality but once battery gets to 10% its really annoying! That said i would buy again!

Smart looking and comfortable with great sound and battery life
The best earbuds I have ever used. They are comfortable to wear and easy to set up. After initial set up they connect immediately using bluetooth. Sound quality is very good and control is by touching the outside of either earbud depending on function needed - pause/restart, change track, answer or end calls etc. They come in a neat charging case which tops up the charge after each use. I have had these for a month and the charge indicator is just down to 40% using them almost every day for an hour or so. They do not cancel out noise completely which I prefer as I want to be aware of people speaking to me or urgent sounds about me. Overall a brilliant set of earbuds for a very reasonable price.

Good value earbuds, outstanding customer service
Bought these earbuds back in June. Good sound quality, very secure fitting, especially for the gym. Battery life is outstanding. The earbuds developed a problem last week, where the right earbud stopped working. Customer support was outstanding and I received a warranty replacement within three days of them diagnosing that the earbud was faulty. Highly recommend this product and the seller.

Mixed feelings but at least the buds won't go missing
Great battery life on the buds and the charging case. It hooks well, though I sometimes have some discomfort from the bud pressing on my ear, but this is to be expected since the manufacturer cannot make a design that would perfectly fit every possible ear shape. The sound quality is good, but the volume could sometimes be low, or require me to push the bud to better fit into the ear canal. Unlike my previous set, these buds cannot connect to a phone and a laptop simultaneously. It also does not announce a caller's name; I have to look at my phone to know who's calling, unlike other buds. But if the goal is to not worry about your buds falling off your ears, this does the job.

A ce niveau de prix, ce casque est en tous points remarquable : - excellente ergonomie, confort d'oreilles convenant à toutes les morphologies avec ses trois embouts souples, le tour d'oreille permet un bon maintien des oreillettes même en cas de mouvements (sport), - très bonne qualité acoustique (enfoncer suffisamment l'embout dans le conduit auditif pour apprécier les graves), - boutons tactiles sur chaque oreillette apportant les fonctions essentielles en lecture (volume sonore, changement de plage de lecture, mise en pause/reprise...), - boîtier de recharge très pratique avec sa batterie intégrée et des indicateurs de charge, - version récente du Bluetooth (5.3) garantissant la compatibilité avec la plupart des transmetteurs.

Kürzlich habe ich mir Bluetooth-Kopfhörer zugelegt, da ich ein hochwertiges und dennoch erschwingliches kabelloses Headset gesucht habe, das eine exzellente Klangqualität bietet und einfach zu bedienen ist. Im Vergleich zu ähnlichen Produkten auf dem Markt hat dieses Headset einige bemerkenswerte Vorteile. Vorteile - Das In-Ear-Design reduziert Außengeräusche und bietet eine hervorragende Klangqualität. - Eine vollständig aufgeladene Batterie bietet eine Wiedergabezeit von bis zu 6 Stunden. - Die benutzerfreundliche automatische Verbindungsfunktion des Headsets beim Einschalten des Ladekoffers spart Zeit. - Der Kopfhörer liefert eine feine Klangqualität und ein völlig immersives Hörerlebnis. - Der Ladekoffer ermöglicht eine zusätzliche Wiedergabezeit von fast 18 Stunden für das Bluetooth-Kopfhörer. - Die Übertragungsgeschwindigkeit ist stabil und schnell, während der Stromverbrauch niedrig ist. - Der Kopfhörer ist wasserdicht und bietet Schutz vor Schäden durch Schweiß und Regen. - Der LED-Bildschirm zeigt deutlich die verbleibende Leistung des Headsets und des Ladekoffers an. - Das Produkt ist preiswert im Vergleich zu ähnlichen kabellosen Kopfhörern auf dem Markt. Nachteile - Es erfolgt kein automatisches Abschalten, wenn der Kopfhörer für längere Zeit nicht verwendet wird. - Die Geräuschunterdrückungsfunktion fehlt. - Der Kopfhörer ist nicht für den professionellen Gebrauch geeignet. - Es gibt keinen eingebauten Sprachassistenten. Alles in allem kann ich den Kauf dieses Produkts aufgrund seiner zahlreichen Vorteile empfehlen. Der Bluetooth-Kopfhörer ist eine ausgezeichnete Wahl für all diejenigen, die nach einem qualitativ hochwertigen und zuverlässigen kabellosen Headset suchen. Ich hoffe, dass meine Bewertung hilfreich war und ich bedanke mich im Voraus für jedes positive Feedback.

Se state cercando un paio di cuffie wireless per musica, chiamate o attività sportive, queste cuffie con sostegno per l'orecchio rappresentano un'opzione eccellente, soprattutto per chi è alle prime armi con questo tipo di dispositivo. Dopo 4 mesi di utilizzo regolare, posso dire con certezza che sono un prodotto che combina affidabilità, comfort e prestazioni La configurazione iniziale è stata semplicissima: accendendo il Bluetooth sul mio smartphone Samsung, le cuffie sono state riconosciute immediatamente. Ogni utilizzo successivo è stato altrettanto fluido, con un accoppiamento automatico istantaneo La qualità del suono è sorprendente, con bassi potenti e alti nitidi che rendono l'esperienza di ascolto davvero piacevole. Anche la qualità delle chiamate è eccellente, con un audio chiaro e senza disturbi. I controlli touch integrati sono intuitivi e reattivi: con un semplice tocco si può regolare volume, risposta Il sostegno per l'orecchio a parer mio è un vero punto di forza. Durante le sessioni di corsa, le cuffie rimangono saldamente al loro posto senza mai muoversi. Sono leggere, confortevoli e si adattano perfettamente al padiglione auricolare, garantendo un comfort anche dopo un'ora di utilizzo costante La batteria è eccellente: dopo 1 settimana di utilizzo di circa 1 ora al giorno , la base di ricarica conserva ancora il 70% di carica. Le cuffie stesse durano tranquillamente sessioni di un'ora o più e si ricaricano in soli 10 minuti nella base. Un altro aspetto positivo è la resistenza al sudore e alla pioggia, che le rendono ottime In conclusione, queste cuffie wireless offrono un rapporto qualità-prezzo incredibile. Tra la facilità di utilizzo, la qualità del suono, il comfort e la lunga autonomia, sono un acquisto perfetto per sportivi, amanti della musica e per chi cerca cuffie affidabili

Ho acquistato queste cuffie per sostituire, affiancare quelle che avevo già di un'altra marca. Le ho trovate ottime, leggere ma solide e non fanno male alle orecchie. Il suono devo dire che non è per niente male, nessun fruscio e ottimi medio bassi. Le ho utilizzate la prima volta per un lungo viaggio in aereo e l'isolamento dal rumore è stato molto buono. I comandi touch sono molto sensibili, con i pro e i contro, puoi gestirle facilmente ma allo stesso tempo devi stare attento a quando te le sistemi. La durata della batteria è ottima, la custodia leggera con coperchio trasparente. Ciò che non è chiaro sono le barre luminose di ricarica che pensavo indicassero il livello di carica delle cuffie, scorrono ma non si riempiono mai e sono sempre ferme alla prima tacca anche se le cuffie si stanno caricando, quindi non ho capito se è un difetto oppure deve funzionare così, ma irrilevante per il funzionamento delle cuffie. Ancora non le ho utilizzate per andare a correre quindi non so dare un giudizio sulla stabilità (ma le sento stabili quindi non dovrebbero dare assolutamente problemi) e nemmeno sull'impermeabilità al sudore o lieve pioggia. Prevedo che dureranno parecchio però spero che alla necessità di sostituirle queste cuffie siano ancora presenti perché le ricomprerei subito. Amazon sempre impeccabile nel suo servizio di consegna. Ottimo.
